Welcome!
Thank you for using ZIP'R Professional For Windows! ZIP'R Pro is
a hard drive utility designed to automatically decompress an
entire program before it is executed, launch the program, and
compress it after it is exited, all accomplished within the
Windows environment. This process saves valuable hard drive
space by storing programs in compressed form when they are not in
use. ZIP'R Pro even achieves a substantial amount of compression
on hard drives that already use an on-the-fly compression
program, such as Stacker, SuperStor, or DoubleSpace! ZIP'R Pro
can use an existing compression program such as PKZIP / PKUNZIP,
ARJ, or LHA, or it can use internal compression routines that are
compatible with PKZIP 2.0!
Requirements
To run ZIP'R Pro reliably, you will need the following:
· Windows 3.1 or Higher & A Mouse
· IBM PC, PC-Compatible or MS-DOS Computer
· Hard Drive and 640K RAM
· EGA Color or VGA Color Monitor
Disclaimer / License Agreement
What is shareware?
Shareware distribution gives users a chance to try software
before buying it. If you try a Shareware program and continue
using it, you are expected to register. Individual programs
differ on details - some request registration while others
require it, some specify a maximum trial period. With
registration, you get anything from the simple right to continue
using the software to an updated program with printed manual.
Copyright laws apply to both Shareware and commercial software,
and the copyright holder retains all rights, with a few specific
exceptions as stated below. Shareware authors are accomplished
programmers, just like commercial authors, and the programs are
of comparable quality. (In both cases, there are good programs
and bad ones!) The main difference is in the method of
distribution. The author specifically grants the right to copy
and distribute the software, either to all or to a specific
group. For example, some authors require written permission
before a commercial disk vendor may copy their Shareware.
Shareware is a distribution method, not a type of software. You
should find software that suits your needs and pocketbook,
whether it's commercial or Shareware. The Shareware system makes
fitting your needs easier, because you can try before you buy.
And because the overhead is low, prices are low also. Shareware
has the ultimate money-back guarantee - if you don't use the
product, you don't pay for it.
Disclaimer - Agreement
By using ZIP'R Professional For Windows and/or the ZIF Editor
Professional, users indicate their acceptance of the following
terms:
"ZIP'R Professional For Windows and the ZIF Editor Professional
are supplied as is. The author disclaims all warranties,
expressed or implied, including, without limitation, the
warranties of merchantability and of fitness for any purpose.
Neither STSI, The STSI BBS, or any STSI employees will be held
responsible for any damages, direct or consequential, which may

"Information in this documentation is subject to change without
notice and does not represent a commitment on the part of STSI.
STSI may make improvements and/or changes in this documentation
or in the products and/or programs described in this
documentation at any time."
ZIP'R Professional For Windows is a "shareware program" and is
provided at no charge to the user for evaluation. Feel free to
share it with your friends, but please do not give it away
altered or as part of another system. The essence of "user-
supported" software is to provide personal computer users with
quality software without high prices, and yet to provide
incentive for programmers to continue to develop new products.
If you find this program useful and find that you are using ZIP'R
Pro and continue to use ZIP'R Pro after a reasonable trial
period, you must make a registration payment of $49.95 (+S&H) to
Stevenson Technical Services, Inc. (STSI). This registration fee
will license one copy for use on any one computer at any one
time. You must treat this software just like a book. An example
is that this software may be used by any number of people and may
be freely moved from one computer location to another, so long as
there is no possibility of it being used at one location while
it's being used at another. Just as a book cannot be read by two
different persons at the same time, ZIP'R Pro should not be used
on two different computers at the same time.
Commercial users of ZIP'R Professional For Windows must register
and pay for their copies of ZIP'R Professional For Windows within
30 days of first use or their license is withdrawn. Site-License
arrangements may be made by contacting STSI at (218) 924-2050.
Anyone distributing ZIP'R Pro for any kind of remuneration must
first contact STSI for authorization. This authorization will be
automatically granted to distributors recognized by the (ASP) as
adhering to its guidelines for shareware distributors, and such
distributors may begin offering ZIP'R Pro immediately. (However
STSI must still be advised so that the distributor can be kept up-
to-date with the latest version of ZIP'R Pro.)
You are encouraged to pass a copy of ZIP'R Pro along to your
friends for evaluation. Please encourage them to register their
copy if they find that they can use it. All registered users
will receive a copy of the latest version of the ZIP'R Pro, along
with a printed manual and bonus disks.
ASP Notice:
STSI is a member of the Association of Shareware Professionals
(ASP). ASP wants to make sure that the shareware principle works
for you. If you are unable to resolve a shareware-related
problem with an ASP member by contacting the member directly, ASP
may be able to help. The ASP Ombudsman can help you resolve a
dispute or problem with an ASP member, but does not provide
technical support for members' products. Please write to the ASP

What Is ZIP'R Pro?
ZIP'R (pronounced "zipper") Pro is a hard drive utility designed
to automatically decompress an entire program before it is
executed, launch the program, and compress it after it is exited,
all accomplished within the Windows environment. This process
saves valuable hard drive space by storing programs in compressed
form when they are not in use. ZIP'R Pro even achieves a
substantial amount of compression on hard drives that already use
an on-the- fly compression program, such as Stacker, SuperStor,
or DoubleSpace! ZIP'R Pro can use an existing compression
program such as PKZIP / PKUNZIP, ARJ, or LHA, or it can use
internal compression routines that are compatible with PKZIP 2.0!
Installation
Backup First!
The first step in testing a new piece of software is to perform a
backup and test its integrity. Since ZIP'R Pro will compress
entire directories into a single file, your potential losses are
much greater if this file becomes lost or corrupted.
The Installation Program
From Program Manager, select File, Run. Browse for files, log to
the drive and directory where you are installing ZIP'R Pro from,
and execute "SETUP.EXE". The ZIP'R Pro For Windows installation
program will ask you where you are installing ZIP'R Pro from
(usually, the current directory), and the location where the
program files should be stored. (The default destination
directory is C:\ZPROWIN.) If you are upgrading from a previous
version, ZIP'R Pro will issue a warning before overwriting the
ZPROWIN.INI file. If you have already set up your registration
information and user preferences in the ZPROWIN.INI file, answer
"N" (No) to instruct ZIP'R Pro not to overwrite this file. When
ZIP'R Pro prompts you for your Windows directory, enter the
directory where you normally store any .PIF files that are used
for DOS programs under Windows. (This is typically the
C:\WINDOWS directory.) ZIP'R Pro will also need to place the
file BWCC.DLL in the Windows system sub-directory. (This is
typically the C:\WINDOWS\SYSTEM sub-directory.) When the
installation is complete, ZIP'R Pro will create a program manager
group and icon, and exit.
ZIP'R Pro can be installed on any drive in your system, including
network drives.
Important!
If you did not install ZIP'R Pro For Windows into the C:\ZPROWIN
sub-directory, include a "SET ZPROWIN=C:\ZPROWIN" statement (or
wherever you put ZIP'R Pro), in your AUTOEXEC.BAT file. If you
add this statement, place it at the top of your AUTOEXEC.BAT
file. Also make sure that you reboot your computer after making
this change to your AUTOEXEC.BAT file to ensure that the changes
have taken effect.

10 Reasons To Use ZIP'R Pro
1. Saves Valuable Hard Drive Space!
Even though hard drive prices have dropped substantially in the
past year, the prices are still out of range for many computer
users. In addition, computer programs have become much larger,
requiring far more space than they used to. ZIP'R Pro can
double, and in some cases triple, the amount of data that can
be stored on a hard drive. Programs like SuperStor, Stacker,
and DoubleSpace typically achieve compression ratios around 30
- 35%. Even hard drives that use these on-the-fly compression
programs can usuallly save an extra 20% or more.
2. Does Not Require 40 - 50K Of Valuable Memory!
Programs like SuperStor, Stacker, and DoubleSpace require that
you surrender 40 - 50K of valuable conventional memory to use
their services. ZIP'R Pro does not! For users who are already
cramped for conventional memory, ZIP'R Pro is clearly the way
to go.
3. Automatically Executes Programs After Decompressing Them.
ZIP'R Pro automatically launches programs after they are
decompressed. This allows you to continue with your work while
ZIP'R Pro takes care of the rest. Rather than manually
decompressing, launching, and recompressing your program, ZIP'R
Pro makes the entire process automatic.
4. Works On Networks.
ZIP'R Pro has the built-in ability to detect when program
execution is occurring in a network environment. ZIP'R Pro
takes extra steps to protect your data, such as making sure
that no one else can access your program at the same time you
are using it. Potentially dangerous situations are monitored
and handled elegantly by ZIP'R Pro.
5. Safe and Reliable!
One comment we receive regularly from our users is that ZIP'R
Pro For DOS is "safe and reliable". We have taken steps to
make sure that same reliability exists in ZIP'R Pro For
Windows.
6. Store Compressed Programs On Any Drive And In Any
Subdirectory.
One feature of ZIP'R Pro is the ability to store compressed
files on any drive and in any subdirectory. This is a powerful
feature, giving you complete control of the compression and
decompression processes.
7. Compress Programs To Floppy Diskettes (PKZIP only)
Having the ability to store compressed files on floppy
diskettes gives you more flexibility, allowing you to
completely remove programs from your hard drive, if necessary.
A special switch within the ZIF Editor Pro allows you to turn
on DOS Verify, ensuring the integrity of your data.
8. Much Cheaper Than Buying A New Hard Drive!
ZIP'R Pro is a great way to double your hard drive capacity
without breaking your budget. Priced at just $49.95 (+$5.00
S&H, USA) (see REGISTER.DOC for more information), ZIP'R Pro
gives you the extra space you need to delay the purchase of
that next hard drive.
9. Compress programs at will using Query option.
Using ZIP'R Pro's Query option, users can decide on-the-fly
whether or not to compress a program. With a simple keypress,
ZIP'R Pro either recompresses the program, or leaves it
uncompressed during times when you're in-and-out more than
usual.
10. Update option makes program recompression fast and easy!
Using the Update option, (available only with PKZIP), ZIP'R Pro
can significantly speed up the recompression process. Rather
than waiting for a completely new compressed file to be
created, the old file is updated with any changes that have
occurred since the file was decompressed. You'll be amazed at
the dramatic difference in speed!
Editing Files
The available editing fields will depend on the interface being
used. The interface level determines what features and fields
will be available when editing a .ZPW file. For more
information, see User Interface.
Beginner, Intermediate, or Advanced Interface
ZPW Filename
The entry typed in this field will be the name of the .ZPW file
used to contain the program preferences entered on this screen.
This file will be referenced on the ZIP'R Pro command line to
execute this program. This filename should reflect the name of
the program being executed. A full path is required.
Executable Filename
This field should contain the full path and filename of the
file to be executed. You must add the correct extension of the
file you wish to execute. If you specify an incorrect
extension, ZIP'R Pro will not be able to find the correct file.
Parameters
This field can optionally contain any necessary parameters that
should be passed to the program being executed. Enter all
options that should be passed to the executable program in this
field.
Application Type
Select whether the program to be executed is a Windows
Application or a DOS Application. ZIP'R Pro For Windows can
execute either type of program from the Windows environment.
Intermediate or Advanced Interface
Compression Type
Place a check mark next to the name of the compression program
you want to use to compress the specified program and its sub-
directories. The following compression utilities are currently
supported by ZIP'R Pro.
ARJ
Internal ZIP (Built-In Compression Compatible With PKZIP 2.0)
LHA
No Compression
PKZIP
The default entry for this field is "Internal ZIP". If you
choose to use ARJ, LHA, or PKZIP, make sure you enter a valid
path for the selected program on the Compression Paths screen
available from the Settings menu.
Test Integrity
When Test Integrity is checked, ZIP'R Pro will tell the
compression program being used to perform an integrity check on
the archived files.
Query Option
The "Query" option is a ZIP'R Pro feature that allows users to
choose, after the program is exited, whether or not it should
be compressed.
If this box is checked, ZIP'R Pro will query (ask) the user
whether or not the program should be compressed each time it is
exited. This allows the user to have more control over the
compression process, instead of having to decide in advance
whether a program should be compressed.
Update Option
(PKZIP and Internal ZIP Compression Only)
The "Update" option is a ZIP'R Pro feature which can
significantly reduce the time required to recompress a program.
Normally, when ZIP'R Pro decompresses a program, it extracts
all of the program files and sub- directories, and deletes the
old compressed file. During the compression process, ZIP'R Pro
creates a new compressed file, and moves all of the program
files and sub-directories into it. This method makes the most
efficient use of hard disk space, but can require a significant
amount of time to recompress the program, depending on the
number and size of files that need to be compressed.
The "Update" option of ZIP'R Pro can save a tremendous amount
of time in this process. Instead of deleting the old
compressed file when the program files and sub-directories are
extracted, ZIP'R Pro leaves it in its original location. When
the compression process starts, ZIP'R Pro uses PKZIP to update
any files and/or sub-directories that have been added or
changed, and deletes any files and/or sub-directories that have
been deleted since the program was extracted. In essence, if
no files or sub- directories were added, changed, or deleted
since the program was decompressed, PKZIP does not need to
update any files. The old compressed file is left in the
directory while PKZIP deletes the program's files and sub-
directories.
Placing a check mark in this box instructs ZIP'R Pro to use the
"Update" method when compressing this program. (Note: The
"Update" option is only available for PKZIP and Internal ZIP
Compression)
The amount of time that can be saved when using the "Update"
option varies between programs. I encourage you to try this
option on a few of your own programs. Here are a few hints
that I've figured out from experimenting with this option.
1. The greatest difference in speed will be noticed on
programs that have large files and/or files that have not
changed. It takes a very long time to compress large files
using the normal compression method. With the update method,
if PKZIP detects that these large files are identical to the
ones already maintained in the compressed file, all it needs to
do is delete these files out of the directory, and the
recompression process is complete!
2. You may notice that any lower-level sub-directories within
the program are always updated when the update method is
enabled. Since directories are deleted when a program is
compressed, PKZIP must create these directories before
decompressing the program. When PKZIP attempts to update the
compressed file, it detects that the directories have
"changed", and therefore, is forced to update them in the
compressed file.
3. This option is useful to speed up the recompression process
on most programs, but it may actually increase the time of
compression on others. The programs that may not compress as
quickly with the update method are ones that have large numbers
of small files and/or ones that have many files added, changed,
or deleted during each session. If you're not sure, use a
watch and time each method to see which way would save the most
time.
Advanced Interface Only
Maximum Users
This field should be used to specify the maximum number of
concurrent users (or accesses) that should be allowed for this
program at the same time. For example, if a network program is
only licensed for five users, you will want to enter 5 in this
field. This tells ZIP'R Pro not to allow more than 5 users
into this particular program at the same time. Under normal
Windows operation, you may run the risk of opening multiple
sessions of the same program at the same time. It would be to
your benefit to enter 1 in this field. That way, ZIP'R Pro
will only allow you to execute one copy of this program at a
time. The default for this field is 1. (Special Note: The
unregistered version of ZIP'R Pro only supports a maximum of 5
concurrent users in one program at the same time. In order to
have access for more than 5 users, you must register ZIP'R
Pro.)
Compressed Filename
Enter the full path and filename of the compressed file that
will be created and used by ZIP'R Pro in this field. After you
exit from the chosen program, ZIP'R Pro creates the compressed
file in the location specified in this field, along with the
filename you specify. When ZIP'R Pro creates the compressed
file, it will append a .ZIP extension for files created with
PKZIP or Internal ZIP compression, a .ARJ extension for files
created with ARJ, or a .LZH extension for files created with
LHA.
Note: The compressed file can be created on any drive and in
any sub-directory, including floppy diskettes. Common
locations for the compressed file include the directory where
the program is executed from, a special archive directory on
your hard drive, a floppy diskette (only available with PKZIP),
or network drive.
Advanced Options
Compress / Decompress Program Only (Do Not Execute)
This advanced feature of ZIP'R Pro allows you to specify
whether or not ZIP'R Pro should attempt to execute the
program file once the program has been decompressed. If this
box is checked, ZIP'R Pro will only decompress the program if
it is in compressed format, and only compress the program if
it is in non-compressed format. This option is potentially
dangerous to the novice user. Caution is advised.
Use Alternate Directory as Program Parent Directory
When this box is checked, the Program Parent Directory field
is enabled for entering the parent directory for the program
being compressed.
See Also: Program Parent Directory
Program Parent Directory
Advanced users will want to use this optional field for
programs with unique requirements. While most programs
maintain their primary executable file in the parent program
directory, some programs maintain their primary executable
file in a lower-level sub-directory. A good example of this
problem is found with Borland Pascal 7.0.
Borland Pascal maintains a master directory called C:\BP.
Underneath this directory are several more lower-level sub-
directories. Instead of placing the executable file BP.EXE
in the C:\BP sub-directory, as most programs would do,
Borland Pascal places this executable file in the C:\BP\BIN
(one of the lower-level sub-directories mentioned above).
In order to compensate for situations like this, ZIP'R Pro,
allows users to specify a parent directory for the program.
In the case of Borland Pascal, the Executable File field
given on the front screen would contain "C:\BP\BIN\BP.EXE".
To compress all files and directories from the main
subdirectory (C:\BP and below), the Program Parent Directory
field would contain "C:\BP".
Use Alternate Directory To Launch Executable Program
When this box is checked, the Launch Directory field is
enabled for entering the directory where the program will be
launched, or executed, from.
See Also: Launch Directory
Launch Directory
This field allows users to optionally enter the directory
where the selected program will be executed from, if it is a
directory other than the one where the program resides. For
example, the program Microsoft Works (C:\WORKS\WORKS.EXE)
could be executed from a directory such as C:\DOCS. This
would allow Microsoft Works to edit files in the C:\DOCS sub-
directory without the need to change to that directory from
within the program.
Check For Child Processes Before Compressing
When this check box is selected, ZIP'R Pro checks to make
sure that the application ZIP'R Pro launched and any
secondary applications launched by the main application are
completely closed down before attempting to recompress the
main program.
As an example, one of our users reported a problem with
Microsoft PowerPoint v4.0 not working properly with ZIP'R
Pro. Apparently, PowerPoint hands control off to a separate
file and terminates the main POWERPNT.EXE file. Once ZIP'R
Pro detected that the main EXE file was no longer in use, it
tried to recompress the entire program, even though a sub-
program was actually running. As another example, we found
that attempting to print a long document from Ami Pro 3.0
causes a similar dilemma. When Ami Pro terminates, Ami Print
(AMIPRINT.EXE) continues to remain on the desktop until all
of the data has been sent to the printer. If Ami Pro is
closed while the printing process is still running, ZIP'R Pro
would again detect that the main application had closed, and
would try to recompress it without waiting for AMIPRINT.EXE
to finish.
This "Child Process Checking" feature (which is enabled by
default) detects when a program launches a "child"
application. For example, ZIP'R Pro is able to detect when
Ami Pro launches Ami Print. Before starting the compression
process, ZIP'R Pro makes sure that BOTH Ami Pro and Ami Print
have been closed.
Swapping
The three fields, labeled "Program Swapping", "IN File
Swapping", and "OUT File Swapping" allow you to specify when
ZIP'R Pro should swap itself to EMS, XMS, or disk. If ZIP'R
Pro does not have to swap, execution of the Program, IN
Commands, and/or OUT Commands occurs much more rapidly than
if swapping is necessary. There are four options available
for these fields.
Default Swap
This instructs ZIP'R Pro to use built-in trip points for
swapping.
Automatic Swap
This instructs ZIP'R Pro to swap itself to EMS, XMS, or
disk ONLY if there is not enough memory available, as
specified by the corresponding Trip Point.
Always Swap
This option instructs ZIP'R Pro to always swap itself to
EMS, XMS, or disk, no matter how much memory is available.
This is the safest method for executing programs and/or DOS
commands, although it can consume more time.
Never Swap
This instructs ZIP'R Pro that it should never swap to EMS,
XMS, or disk, no matter how much (or how little) memory is
actually available. Use this option carefully, as it could
cause programs and DOS commands to issue out of memory
error messages.
Trip Point
This option allows users to specify the trip point (or
memory availability requirement) that should be used for
ZIP'R Pro to decide when it should swap itself to EMS, XMS,
or disk. The trip point only works when "Automatic Swap"
is selected as the swapping type.
Compression Options
PKZIP Compression Options
These PKZIP / PKUNZIP options may be used to choose less
compression in exchange for more speed, or more compression
in exchange for less speed.
PKZIP 2.04 Compression Options
e0 No Compression / Store (PKZIP 2.0 Only)
es Super-Fast Compression (PKZIP 1.1 or 2.0)
ef Fast Compression (PKZIP 2.0 Only)
en Normal Compression (Default) (PKZIP 2.0 Only)
ex Maximum Compression (PKZIP 1.1 or 2.0)
In addition to these options, additional options are
available with PKZIP 2.04g to solve specific hardware and
software compatibility problems. These options are as
follows:
Disable 32-Bit Instruction Usage
Disable DPMI Support
Use Slow MemCopy
Disable EMS Usage
Disable XMS/UMB Usage
Disable Network Detection
Each of these parameters is explained in the troubleshooting
section of the PKZIP documentation. To use any of these
options, place a check mark beside the corresponding entry on
the Compression Options screen.
ARJ Compression Options
The following compression options are available for people
using ARJ.EXE to compress / decompress programs. The default
ARJ compression setting is to use the -m1 switch.
-m0 switch
-m1 switch
-m2 switch
-m3 switch
-m4 switch
-m1 -jm switch
-m2 -jm switch
-m1 -jm1 switch
-m2 -jm1 switch
Test Temporary ARJ Archive
In addition to these options, ARJ allows users to test the
temporary archive that is created when compressing files.
To do this, place a check mark in the "Test Temporary
Archive" check box.
Internal ZIP Compression Options
The following compression options are available when using
Internal ZIP compression:
Compression Method
Use Best Method (default)
Deflate
Implode
Shrink
Store
When using Internal ZIP, you can specify if files should be
compressed using the Deflate, Implode, Shrink, or Store
methods, or you can let ZIP'R Pro use the Best method,
depending on each file. The best compression ratios can be
achieved using the Deflate method, while the least
effective is Store, which simply stores the program file
inside the .ZIP file without compressing it.
Compression Method Options
Deflate Level
When the deflate compression method is being used by the
Internal ZIP compression routines, a deflate level can be
specified to improve the overall compression. The range
of values is from 1 to 9, with 1 being the least
compression, and 9 being the most. The higher this value
is set, the more time will be required to compress the
program.
Implode Match Length & Implode Repetitions
The implode match length and repetitions settings can be
adjusted to improve compression or speed on files that
are imploded. The match length must be in the range of 4
to 288, and the repetitions much be in the range of 4 to
960. The default value for both fields is 4. The higher
the numbers, the greater the compression will be on
imploded files.
Special Options
Use Selective Extraction
(PKUNZIP Only)
When this box is checked, Selective Extraction is turned on,
and only the files listed in the Selective Extraction File
List will be extracted from the .ZIP file when this program
is decompressed. The original .ZIP file is preserved
(similar to the process used when Update Option is enabled).
After the program is exited, the original .ZIP file is
updated with any changes that were made during the current
session. When Selective Extraction is enabled, Query Option
is ignored, and the Update Option is always used. All
multiple-user access features are disabled when using
Selective Extraction. Only one user is allowed into a
program at a time when Selective Extraction is enabled.
See Also: Selective Extraction File List
Selective Extraction File List
This box contains a list of the files that should be
extracted from the .ZIP archive when the program is
decompressed. Rather than extracting an entire archive, you
can choose to decompress only the files that are needed for
program execution. This can dramatically speed up the
compression and decompression process. For example, to run
the Norton Utilities SFORMAT.EXE, the only files needed are
SFORMAT.EXE and NORTON.INI. By entering these two files,
PKUNZIP will only extract the two files specified before
executing SFORMAT.EXE.
When entering filenames into this file list, wild cards may
be used, such as *.EXE, *.DOC, ???.CFG, etc. If a filename
is entered that does not exist in the .ZIP file, PKUNZIP.EXE
will not attempt to extract it, and it will not issue an
error message.
Be very careful when using this option! If you forget to
extract a file necessary for proper program execution, your
program could terminate unexpectedly or issue error messages.
Use Selective Exclusion
(PKUNZIP Only)
When this box is checked, Selective Exclusion is turned on,
and all files listed in the Selective Extraction File List
will be excluded from the extraction process when the .ZIP
file is decompressed. When Selective Exclusion is enabled,
Query Option is ignored, and the Update Option is always
used. All multiple-user access features are disabled when
using Selective Exclusion. Only one user is allowed into a
program at a time when Selective Exclusion is enabled.
See Also: Selective Exclusion File List
Selective Exclusion File List
This box contains a list of the files that should be excluded
from the extraction process when the .ZIP archive is
decompressed. Rather than extracting an entire archive, you
can choose to exclude certain files that are not needed for
program execution or operation. This can dramatically speed
up the compression and decompression process. For example,
most programs do not require *.DOC files to be present in
order to run successfully. By entering "*.DOC" into the
Selective Exclusion File List, PKUNZIP will not extract these
files, saving time during the compression and decompression
processes, and disk space while the program is running.
When entering filenames into this file list, wild cards may
be used, such as *.EXE, *.DOC, ???.CFG, etc.
Be very careful when using this option! Excluding a file
that is necessary for proper program execution could cause
your program to terminate unexpectedly or issue error
messages. Also remember that if Selective Extraction AND
Selective Exclusion are both enabled, Selective Exclusion
files take precedence. That means that if PROGRAM.EXE is
listed in both file lists, it will always be excluded.
Use IN Commands
When this box is checked, IN Commands are enabled, and any
DOS commands listed in the IN Commands memo field will be
executed prior to executing the selected program.
See Also: IN Commands
IN Commands
IN Commands are DOS commands that are executed prior to
running the selected program. An example of this would be to
swap a printer port prior to executing the program. Another
example would be to flush and disable write caching before
running a disk utility program.
To use this feature, enter any necessary DOS commands that
should be executed prior to going "IN" to the program in the
corresponding memo field.
Important! Do NOT attempt to invoke or remove TSR (Terminate
and Stay- Resident) programs from memory with IN or OUT DOS
commands. This is virtually guaranteed to cause conflicts
with ZIP'R Pro. If you need to invoke a TSR before running a
program, or remove one after exiting a program, see the
section on TSR's.
Use OUT Commands
When this box is checked, OUT Commands are enabled, and any
DOS commands listed in the OUT Commands memo field will be
executed after the selected program has been exited or
terminated.
See Also: OUT Commands
OUT Commands
OUT Commands are DOS commands that are executed after exiting
the selected program. An example of this would be to swap a
printer port back to its original state after exiting from
the program. Another example would be to re-enable write
caching, if it had been previously disabled using the IN
Commands, after exiting from a disk utility program.
To use this feature, enter any necessary DOS commands that
should be executed after going "OUT" of the program in the
corresponding memo field.
Important! Do NOT attempt to invoke or remove TSR (Terminate
and Stay- Resident) programs from memory with IN or OUT DOS
commands. This is virtually guaranteed to cause conflicts
with ZIP'R Pro. If you need to invoke a TSR before running a
program, or remove one after exiting a program, see the
section on TSR's.
Use TSR Pre-Program Commands
When this box is checked, TSR Pre-Program Commands are
enabled, and any DOS commands listed in the TSR Pre-Program
Commands memo field will be executed prior to executing the
selected DOS program.
See Also: TSR Pre-Program Commands
TSR Pre-Program Commands
Just like IN Commands, TSR Pre-Program Commands are DOS
commands that executed prior to executing the selected DOS
program. The main difference is that TSR Pre-Program
Commands invoke one or more TSR (Terminate-and-Stay-Resident)
programs. TSR's can be a bit tricky to handle due to the
fact that ZIP'R Professional cannot tell what memory has been
used by any TSR's that load later. But ZIP'R Professional
makes TSR's easier to manage by creating a "TSR Container
File". This file is simply a temporary batch file that
contains commands that surround the command line used to
execute the program with the TSR (Pre) and TSR (Post)
commands. When the program is executed, this batch file is
executed instead of the program, allowing TSR's to load and
unload while ZIP'R Professional is dormant. No user
intervention is required. ZIP'R Professional automatically
creates, and then deletes this temporary batch file. TSR's
that can be loaded and unloaded via command line parameters
can usually be invoked successfully with this method. The key
point to remember is to unload TSR's in the REVERSE order
that they were loaded. The following example illustrates
this concept more clearly.
TSR (Pre) Commands :
TSR1 (Load)
TSR2 (Load)
TSR (Post) Commands:
TSR2 (Unload)
TSR1 (Unload)
TSR2 must be unloaded first, since it was the last TSR
loaded, and is loaded last in memory. Once TSR2 is unloaded,
TSR1 may be safely unloaded, because it is now the last TSR
in memory.
The important point to remember is that if you load a TSR
before executing the program, you MUST unload it after
exiting the program. Otherwise, control will not be returned
to ZIP'R Pro. When this happens, ZIP'R Pro will not perform
the compression process, resulting in several problems. If
the Update option was enabled, the compressed file will still
be in the compressed file directory, and the program files
will still be in the program directory. This could be
dangerous, if you don't know what you're doing. It is
recommended that you delete the compressed file before
attempting to execute the program again. You may also find
some files in the \ZPROWIN sub-directory with a .U00 or .P00
extension. If no one else is accessing the program at the
time, you should delete them. To avoid such problems as
these, either don't load TSR's at all, or make sure that you
unload them using the TSR (Post) Commands.
Use TSR Post-Program Commands
When this box is checked, TSR Post-Program Commands are
enabled, and any DOS commands listed in the TSR Post-Program
Commands memo field will be executed after exiting from, or
terminating, the selected DOS program.
See Also: TSR Post-Program Commands
TSR Post-Program Commands
Just like OUT Commands, TSR Post-Program Commands are DOS
commands that executed after exiting from, or terminating,
the selected DOS program. The main difference is that TSR
Post-Program Commands remove one or more TSR (Terminate-and-
Stay-Resident) programs from memory. TSR's can be a bit
tricky to handle due to the fact that ZIP'R Professional
cannot tell what memory has been used by any TSR's that load
later. But ZIP'R Professional makes TSR's easier to manage

parameters can usually be invoked successfully with this
method. The key point to remember is to unload TSR's in the
REVERSE order that they were loaded. The following example

TSR1 (Load)
TSR2 (Load)

TSR1 may be safely unloaded, because it is now the last TSR

Floppy Options
This screen allows users to select options to be invoked when
creating a compressed file on a floppy diskette.
Important Note: Options for floppy diskette compression will
only work when PKZIP / PKUNZIP is used as the compression
program. Also note that the Update option can NOT be used when
compression is occurring to floppy diskettes.
One of the following options can be selected as the default
when creating a compressed file on a floppy diskette.
Erase All Files and Sub-Directories
Format Destination Diskette (Quick Format)
Format Destination Diskette (Full Format)
Format Low-Density Disk in High-Density Drive (Quick Format)
Format Low-Density Disk in High-Density Drive (Full Format)
For an explanation of these options, see the Backup Guide
supplied with PKZIP 2.0.
Use DOS Verify
If you want DOS Verify to be turned on when compressing files
to a floppy diskette, place a check mark in the "Use DOS
Verify" check box. This adds an extra level of security to
make sure that files are created error-free.
Opening and Deleting Files
Also available from the File Menu is the ability to open or
delete a previously created .ZPW file. Use the Open File screen
to search through available drives and directories for the .ZPW
file you want to edit. Once you've located the file you want to
open, double-click on it with the mouse, or press [ENTER] when it
is selected with the highlight bar, and ZIP'R Pro will read the
information and import it into the editing screen to be viewed or
modified.
If you choose "Delete" from the File Menu, a similar dialog box
will appear, allowing you to search through available drives and
directories for the .ZPW file you want to delete. When you find
it, double-clicking on it, or pressing [ENTER] when it is
selected with the highlight bar will display a confirmation
dialog box to confirm that you want to delete the selected file.
Browsing
One powerful feature of the ZIP'R Pro is the ability to browse
for files using file and directory list boxes. Selecting the
"Browse" button will display a file browsing screen to allow you
to search for the executable file for the designated program.
Once a file is selected from this screen, the drive, directory,
and executable file will be automatically pasted into the
"Executable File" field.
Using The ZIP'R Pro Desktop
The ZIP'R Pro desktop allows you to create new files, edit
existing files, and run programs, all within a single interface.
To create a new file, select New from the File menu. To edit an
existing file, select Open from the File menu, or position your
mouse over an icon and press the right mouse button. Either of
these methods will let you edit an existing file. To run a
program, double-click on the icon associated with the program you
want to run. ZIP'R Pro will decompress the program (if
necessary), execute it, and recompress it using the options you
specified when you set up the file.

Advanced Options (Defaults)
Cluster Size Calculation (Auto Detect, Manual)
When ZIP'R Pro uses the Accurate File Size Calculation, it
needs to know the size of the allocation unit used on the
program's disk drive. By selecting "Auto Detect", you can
instruct ZIP'R Pro to automatically detect the true cluster
size. If you select "Manual", you can enter the cluster size
you want ZIP'R Pro to use when making these calculations.
When in doubt, use Auto Detect.
Cluster Size
If the Cluster Size Calculation option is set to "Manual",
enter the cluster size that ZIP'R Pro should use for disk
space calculations.
Accurate File Size Calculation
Before ZIP'R Pro is able to decompress a program, it must
calculate the amount of disk space that will be required to
hold the decompressed program. There are 4 levels of
accuracy/speed available. The more accuracy that is desired,
the slower the calculation process becomes.
Level 1
If Level 1 is selected, ZIP'R Pro "guesses" at the amount
of space required to hold the decompressed program files.
Level 2
If Level 2 is selected, ZIP'R Pro performs a more accurate
calculation for the space needed to successfully store the
decompressed files. This level is recommended for most
users, since the calculation used is fairly accurate, and
usually errs on the conservative side.
Level 3
Level 3 uses the same calculation as level 2, but with one
difference in the video display. Level 2 views the
contents and total size of the archived file by redirecting
the output to the screen. Level 3 redirects this output to
a file, which takes longer. If you use Level 3, you won't
see the archive file contents "flying-by" on the screen,
but it will take a bit longer to process it.
Level 4
This is the most complicated (and most time-consuming)
method of calculating the space needed for the decompressed
files. But, it is EXACT. ZIP'R Pro reads the size of each
file from the archive file contents, and uses the Cluster
Size to determine exactly how much space a file will
consume once it is extracted. This method takes a longer
time to complete, but there should be NO DOUBT about
whether enough space exists on the hard drive to complete
the decompression process successfully.
Manually Create Sub-Directories Under OS/2
Users who are running ZIP'R Pro under OS/2 in combination
with Novell NetWare will want to enable this option.
Problems have been reported when using PKUNZIP in a global
network session, where PKUNZIP cannot create the sub-
directories properly during the decompression process. (This
problem has been reported to PKWare.) When this option is
enabled, ZIP'R Pro will manually created the needed sub-
directories before instructing PKUNZIP to decompress the
compressed file.
Use Atomic Lock Files
When the network/multitasker features of ZIP'R Pro are being
used, users can specify whether or not atomic lock files are
used. For a discussion on atomic lock files, see the
"Networks / Multitaskers" section of this documentation.
Sorted Extraction
(PKUNZIP Only)
When Sorted Extraction is set to "Yes", ZIP'R Pro will
extract files from the .ZIP archive in alphabetical order.
This feature is especially useful on network drives that
generally prevent utilities of this nature from working. If
this option is set to "No", files are extracted in the order
in which they appear in the file.
Sub-Directory Deletion
(PKZIP 2.04g Only)
Disabling sub-directory deletion will instruct PKZIP 2.04g
not to delete any of the program's sub-directories (located
under the parent directory) when compressing a program. The
default is On, which means that PKZIP will automatically
delete the lower level sub-directories once the compression
process is complete.
Windowed Compression
When Windowed Compression is set to on, ZIP'R Pro will
attempt to execute the program compression process within the
limits of a window. Otherwise, program compression will
occur on a full DOS screen.
Windowed Decompression
When Windowed Decompression is turned on, ZIP'R Pro will
attempt to execute the program decompression process within
the limits of a window. Otherwise, program decompression will
occur on a full DOS screen.
Compression Paths
ARJ Path
Enter the appropriate path to the file ARJ.EXE in the format
"C:\ARJ\". Do not add the actual filename or extension. If
this field is left blank, or if ZIP'R Pro cannot find ARJ.EXE
in the path entered, it will search the ZIP'R Pro sub-
directory. If it is still unable to locate ARJ.EXE, it will
search the DOS Path. If ARJ.EXE is not located, an error
message will be issued.
LHA Path
Enter the appropriate path to the file LHA.EXE in the format
"C:\LHA\". Do not add the actual filename or extension. If
this field is left blank, or if ZIP'R Pro cannot find LHA.EXE
in the path entered, it will search the ZIP'R Pro sub-
directory. If it is still unable to locate LHA.EXE, it will
search the DOS Path. If LHA.EXE is not located, an error
message will be issued.
PKZIP Path
Enter the appropriate path to the files PKZIP.EXE and
PKUNZIP.EXE in the format "C:\PKZIP\". Do not add the actual
filename or extension. Both of these files must be located
in the same sub-directory. If this field is left blank, or
if ZIP'R Pro cannot find either of these two files in the
path entered, it will search the ZIP'R Pro sub-directory. If
it is still unable to locate them, it will search the DOS
Path. If PKZIP.EXE or PKUNZIP.EXE is not located, an error
message will be issued.
Delays
Non-registered copies of ZIP'R Pro will ignore any changes on
this screen and use the default settings. Registering ZIP'R Pro
with the author will allow you to completely remove the prelog
pause and delay.
Pause during Prelog
Place a check mark in this box if you want ZIP'R Pro to pause
with a "Press Any Key" message when the prelog screen is
displayed.
Delay during Prelog
Place a check mark in this box if you want ZIP'R Pro to delay
when the prelog screen is displayed. Enter the amount of the
delay in the Prelog Delay field.
Prelog Delay
Enter the number of seconds ZIP'R Pro should pause on the
prelog screen before ZIP'R Pro attempts to execute the
selected program. This field is only valid if the "Delay
during Prelog" box has a check mark in it. Experienced ZIP'R
Pro users can set this field to 0, which will prevent ZIP'R
Pro from displaying the prelog screen. Novice users may want
to set this field to 4, to allow a short time to view the
information displayed on the prelog screen.
Video Options
Launch Compress As
The Launch Compress As setting allows you to specify how
program compression will occur. If you select Icon,
compression will occur in a minimized DOS session, allowing
you to continue your normal work without monitoring the
compression process. Otherwise, if you select "Use
zprocess.pif setting", ZIP'R Pro will use the setting defined
in the file ZPROCESS.PIF which was transferred to your
\WINDOWS directory during the installation process.
Launch Decompress As
The Launch Decompress As setting allows you to specify how
program decompression will occur. If you select Icon,
decompression will occur in a minimized DOS session, allowing
you to continue your normal work without monitoring the
decompression process. Otherwise, if you select "Use
zprocess.pif setting", ZIP'R Pro will use the setting defined
in the file ZPROCESS.PIF which was transferred to your
\WINDOWS directory during the installation process.
Screen Writes
This option allows you to specify whether ZIP'R Pro should
write information to the screen using BIOS or Direct. The
default is Auto Detect.
Scan Activity Indicator
The scan activity indicator is a small display that occurs on
the top of the compression screen when ZIP'R Pro is scanning
for added or deleted files. If File Count is selected, ZIP'R
Pro will display the number of the current file that it is
checking as it proceeds through the file list. If Twirling
Bars is selected, a pair of twirling bars will spin, letting
you know that there is continued activity on the part of
ZIP'R Pro. Select None if you do not want either of these two
options displayed. (Note: This process has been speeded up
significantly from the original ZIP'R, and in most cases, you
probably won't notice this indicator. It is most useful on
extremely large archives with many files.)
Register ZIP'R Pro
Registration Name
If you are a registered user of ZIP'R Pro, enter your
registration name in the Registration Name field. The
Registration Name cannot be longer than 36 characters. If you

User Interface
One of the most useful features of ZIP'R Pro is the ability to
specify a user interface. The user interface level determines
what features will be available when editing a .ZPW file and
modifying the default settings for ZIP'R Pro. Here's a general
overview of the benefits of each of the user interface levels:
Beginner
The Beginner interface is for novice users who want to be
sheltered from all of the complexities of ZIP'R Pro. With the
Beginner level, users can simply enter the name of the .ZPW
file being created, the executable program, and any needed
parameters. All advanced options are hidden from view, making
ZIP'R Pro less intimidating. When Beginner is selected,
Internal ZIP compression is used on programs, meaning that no
outside programs are needed to operate ZIP'R Pro.
Intermediate
The Intermediate interface is for users who want to use an
external compression program, such as ARJ, LHA, or PKZIP, or
who want to specify the settings for the Test Integrity, Query
Option, or Update Option fields. While these options are
hidden from view on the Beginner level interface, these options
are accessible to intermediate users.
Advanced
The Advanced interface is for users who want to have access to
all of the features available in ZIP'R Pro. All of the desired
"bells and whistles" can be accessed when using the Advanced
interface. This includes Selective Extraction and Exclusion,
IN and OUT commands, TSR commands, Advanced Options,
Compression Options, and Floppy Compression Options. Advanced
users can specify the name and location of the compressed file,
storing it on any available drive and directory.
The user interface level can be changed at any time. Beginner
users can step up to an intermediate or advanced interface, and
advanced users can step down to an intermediate or beginner
interface. Files created within one interface can be opened
using another interface. This will not affect the integrity of
the .ZPW file being edited.
What Happens When I Execute ZIP'R Pro?
Several things take place through the course of using ZIP'R Pro.
Here is a brief summary of what ZIP'R Pro does, and what you can
expect to see on the screen:
When using the following variable on the ZIF Editor's .ZPW
editing screen:
ZIF Filename: C:\ZPROWIN\AMIPRO.ZPW
Executable File: C:\AMIPRO\AMIPRO.EXE
Parameters:
Maximum Users: 1
Compressed File: C:\AMIPRO\AMIPRO
Compression ZIP
Type:
and entering the command line: ZPROWIN AMIPRO
the following events would take place:
1. ZIP'R Pro checks for the existence of the .ZPW file. If the
.ZPW file cannot be found, ZIP'R Pro issues an error message. If
ZIP'R Pro was able to locate the .ZPW file, ZIP'R Pro proceeds to
step #2.
2. ZIP'R Pro displays the prelog screen. This screen contains a
wealth of information for users with different system
configurations. The following is a summary of this information,
and what it means.
Conventional

from the specified .ZPW file.
Selective Exclusion Commands (SXC)
Displays the total number of Selective Exclusion entries read
from the specified .ZPW file.
TSR Commands (TSR)
Displays the total number of TSR DOS Commands read from the
specified .ZPW file.
AFSC Level
Displays the Accurate File Size Calculation level selected for
ZIP'R Pro.
Program Path/Name
Displays the program path and executable filename as set up in
the specified .ZPW file.
Parameters
Displays any parameters that will be passed to the program
being executed, as set up in the specified .ZPW file.
Compressed Filename
Displays the path and filename of the compressed file that will
be created when ZIP'R Pro compresses the program. The
extension that appears on this field should reflect the name of
the compression program being used. (PKZIP will use .ZIP, ARJ
will use .ARJ, LHA will use .LZH, and NONE will not display an
extension.)
3. After displaying the prelog screen, ZIP'R Pro checks the
validity of the drive and path that was entered in the .ZPW file.
If ZIP'R Pro cannot find the drive and/or path, it issues an
error message. If ZIP'R Pro is able to locate the drive and path
specified, it then checks for the existence of a compressed file,
bearing the name entered in the "Compressed FileName" field of
the .ZPW editing screen. ZIP'R Pro checks for the existence of
the compressed file, and if it is found, attempts to decompress
it using the corresponding decompression utility (step #4). If
ZIP'R Pro does not find a compressed file, it skips the
decompression process and begins to execute the program (step
#5).
4. ZIP'R Pro begins the decompression process by viewing the
compressed file and calculating the disk space required to
decompress the entire file. The accuracy level of this
calculation depends on the setting of the Accurate File Size
Calculation (Level 1 - 4) and the Cluster Size setting.
If ZIP'R Pro determines that there is not enough disk space
available to decompress the entire file, a warning message will
be issued. If ZIP'R Pro determines that sufficient disk space is
available to decompress the entire file, it executes the
necessary decompression program to decompress the file.
5. The next step performed by ZIP'R Pro is automatic execution
of the specified program. This step makes ZIP'R Pro unique from
most other compression / decompression utilities. Rather than
forcing users to compress and decompress programs separately,
ZIP'R Pro does it all automatically. If ZIP'R Pro is not able to
locate the executable file, it issues an error message stating
the problem. If ZIP'R Pro is able to locate the executable file,
it executes the program normally, along with any parameters set
up in the .ZPW file.
6. If Query Mode is enabled, ZIP'R Pro pops up a screen
prompting you whether or not you want to compress the program you
just exited. If you answer Yes, ZIP'R Pro continues with step
#7. If you answer No, ZIP'R Pro skips to step #8.
7. Once the program is exited, ZIP'R Pro begins to compress (or-
recompress) the program directory using the compression utility
specified in the .ZPW file. The amount of time this takes
depends on the number and size of the files being compressed. If
Update Mode is enabled, ZIP'R Pro simply updates the archive file
with any changes that have occurred since the file was
decompressed. New files are added to the compressed file,
modified files are updated in the compressed file, and deleted
files are removed from the compressed file.
8. After the compressed file has been successfully created,
ZIP'R Pro displays a delay screen for unregistered users. To
remove this delay, please read the file REGISTER.DOC to find out
how to register ZIP'R Pro. Once this is complete, ZIP'R Pro
returns control of the computer back to the Windows environment.
Integrating ZIP'R Pro Into Windows
While ZIP'R Pro allows you to access all of your programs and
execute them directly from the desktop interface, you may want to
launch them from a standard Program Manager icon. To accomplish
this, follow the example given below.
Windows Program Item Properties Example:
OLD Description: AmiPro
Command Line: AMIPRO.EXE
Working Directory: C:\AMIPRO
NEW Description: AmiPro
Command Line: ZPROWIN AMIPRO
Working Directory: C:\ZPROWIN
This format will allow you to launch a program without directly
interacting with ZIP'R Pro.
Modifying the Zprocess.Pif File
When ZIP'R Pro compresses or decompresses a program, it launches
the file ZPROCESS.EXE file, which uses the settings in the file
ZPROCESS.PIF. If your system is low on conventional memory, and
you receive a Windows error that there is not enough memory
available to launch this file/program, you may decrease the
amount of memory required in this PIF file. The file
ZPROCESS.PIF is location in your Windows directory (usually
C:\WINDOWS).
The setting that you may want to change is the "Memory
Requirements: KB Required" field. The default value for this
field is 512K. You may reduce this value to allow Zprocess to be
executed at lower memory levels.
If you decide to lower this value, it would be wise to use PKZIP
/ PKUNZIP instead of Internal ZIP compression. Since Internal
ZIP requires more memory, large programs containing many files
could cause Internal ZIP to generate "Insufficient Memory" or
"Out of Memory" errors. If at all possible, you should leave the
KB Required field at 512K, just to be safe.
Important: If you change the defaults in this file, you must do
so at your own risk! (Please read STSI's disclaimer at the top
of this documentation.)
How Effective Is ZIP'R Pro?
ZIP'R Pro can save a typical computer user a substantial amount
of hard drive space. Most users have several programs on their
hard drives that are seldom used, but take up a tremendous amount
of hard disk real-estate. Rather than deleting these programs
completely, ZIP'R Pro allows these programs to be accessed when
needed, storing them in a compressed form when they are not in
use. The amount of hard drive space saved depends totally on the
effectiveness of the compression program used by ZIP'R Pro. As
compression programs improve, so will the ratios that ZIP'R Pro
is able to achieve.
The compression programs used by ZIP'R Pro do not provide "on-the-
fly" data compression. As a result, there is a time delay during
the compression and decompression processes. However, ZIP'R Pro
does not require 50K of valuable memory, either. In addition,
ZIP'R Pro does not degrade the performance of the computer system
as the "on-the-fly" data compression programs do.
A performance comparison of the three compression programs
currently supported by ZIP'R Pro is shown in the following table.
The test directory consisted of 33 files, plus a sub-directory
which contained an additional 17 files.
Test Directory Size Using Microsoft MS-DOS 5.0
Compression Type Bytes Compression Overall
Compression
Original Baseline 2,980,853 - -
MS-DOS 2,980,853 0% 0%
New Baseline 2,980,853 - 0%
Additional compression obtained using ZIP'R Pro:
Compression Bytes Compression Overall

LHA Compression 1,444,864 27% 52%
(LHA)
ARJ Compression 1,423,872 29% 52%
(ARJ)
You can see by this table that SuperStor was only achieving an
overall compression ratio of 33%. Using ZIP'R Pro with PKZIP 2.0
allowed an extra 20% savings on hard drive space!
Cautions When Using ZIP'R Pro
Do NOT attempt to use ZIP'R Pro to compress any directories
containing files that are referenced in your CONFIG.SYS or
AUTOEXEC.BAT. If you wish to compress the DOS sub-directory,
copy any such files to the root directory of the hard drive, and
update the paths in your CONFIG.SYS and AUTOEXEC.BAT. Also be
cautious when compressing directories that contain memory
managers, caches, and utilities that may be needed to boot your
machine. These directories may be compressed, but any files
needed for booting the machine must be copied to the root
directory, and the CONFIG.SYS and AUTOEXEC.BAT paths updated.
Keep in mind that in order to properly decompress a program,
there must be enough free space on the hard drive to contain all
the extracted files in addition to the original compressed file.
After the files have been successfully extracted, the compressed
file is deleted. Likewise, when compressing a program,
sufficient space must be available for the original program files
and the newly created compressed file. After the compressed file
has been successfully created, the original program files are
deleted.
When upgrading to PKZIP 2.0, test the reliability of the
compression and decompression processes before trusting it with
your data! PKZIP 2.0 has some documented problems with fast
machines (486/25 and up) using external CPU memory caches. Read
the troubleshooting section of the PKZIP 2.0 documentation for
more information.
Troubleshooting / Common Problems
Problem #1:
The most common problem among ZIP'R Pro users is incorrect setup
of the .ZPW file being used. The following list gives some hints
and tips for filling in each field when editing a .ZPW file.
ZIP'R Pro Filename
Make sure that this field contains only characters that can be
used as part of a filename. To find out which characters may
or may not be used as part of a DOS filename, see your DOS
reference manual.
Executable File
You must place the correct extension of the program to be
executed on the filename. If ZIP'R Pro issues an error message
that it contain find the program, make sure you have check the
extension on this field.
Parameters
Enter any parameters exactly as you would enter them after the
program name, if you were using a DOS command line.
Compressed Filename
Do not place an extension for the compressed file in this
field. ZIP'R Pro automatically adds the correct extension at
run time. If the compression program is PKZIP, the extension
will be .ZIP. If the compression program in ARJ, the extension
will be .ARJ, and likewise, if the compression program is LHA,
the extension will be .LZH.
Maximum Users
Make sure that the maximum number of concurrent users does not
exceed 256. ZIP'R Pro will only allow 256 users in one program
at the same time.
Compression Type
If you want to decompress a previously compressed program
without recompressing it, use the Query option, and select "No"
when prompted. Do not try to changed the type of compression
if your program is currently in a compressed state.
Test Integrity
Check this box ONLY if you want the compression program to
perform an integrity check on the archived files once they have
been compressed.
Query Option
Check this field when you want ZIP'R Pro to prompt you before
compressing a program. This allows you to specify whether a
program should be compressed "on-the-fly".
Update Option
This option is only available for use when ZIP (PKZIP /
PKUNZIP) is selected as the Compression Type. If any other
option is selected, the Update Option field will be grayed and
disabled.
Problem #2:
If you receive the error message, "Unable to run COMMAND /C ...",
you are probably running DR DOS, and do not have COMMAND.COM
available on your path. For some reason, DR DOS does not copy
COMMAND.COM into the \DRDOS sub- directory at installation time,
making it unavailable on the path. The solution here is simply
to copy COMMAND.COM from the root directory into the \DRDOS sub-
directory. Another alternative is to add the root directory to
the PATH= statement in the AUTOEXEC.BAT file.
ZIP'R Pro is able to detect if COMMAND.COM cannot be found, and
therefore issues a warning message.
Problem #3:
If ZIP'R Pro won't compress the program's files and sub-
directories after it is exited, check the .ZPW file. If the
fields are all correct, check the \ZPROWIN sub-directory for
files with any of the following extensions:
.U00 through .UFF
.P00 through .PFF
.N00 through .NFF
.CSF
.DSF
.SXF
.SXT
.ZSF
These are token files created by ZIP'R Pro to track concurrent
access to a compressed file on networks and under multitaskers.
Normally, these files are deleted when the program is exited.
However, if the computer hangs, these files will not be deleted,
and will prevent ZIP'R Pro from compressing the program's files
and sub-directories. The filename should match the name of the
compressed file specified in the .ZPW file. ZIP'R Pro provides a
quick and easy solution to the problem of leftover signal files.
Make sure that ZIP'R Pro is not being used on any active
programs, execute the ZIF Editor, and run the Cleanup Files
option from the ZIP'R Pro Settings menu.
The Cleanup Files option is used to erase all signal files in the
ZIP'R Pro sub-directory. This option should be used with care to
ensure that no other processes are using ZIP'R Professional.
(Erasing signal files that are in use
by other programs could cause "weird" behavior.)
The most common reason that any of these types of files would be
left behind is usually due to a computer hang. When the computer
hangs, control is not returned to ZIP'R Pro, so ZIP'R Pro cannot
delete them as part of the cleanup process. They can also be
left behind due to a TSR not be unloaded in the TSR (Post)
Command process if it was loaded in the TSR (Pre) Command
process. As mentioned earlier, this can also cause control to
not be returned to ZIP'R Pro, in which case, these files would
not be deleted.
Problem #4
If you are having trouble getting ZIP'R Pro to run properly,
there is a special "/TEST" parameter that can aid you in
diagnosing your problem. When typing the command line to run
ZIP'R Pro, instead of typing "ZPROWIN FILENAME", you can type
"ZPROWIN FILENAME /TEST". This extra parameter will allow you to
view several screens of parameters. These parameters contain
information that ZIP'R Pro is reading from the system, the
ZPROWIN.INI file, and the individual .ZPW file. This can be used
to find out if ZIP'R Pro is reading the necessary files
accurately. If you detect a problem when using the /TEST
parameter, please contact STSI at (218) 924-2050.
Note: The keys (CTRL + Break) can be used on the ZIP'R Pro prelog
screen to exit from ZIP'R Pro. Although this is not recommended,
it will enable users to stop execution in an emergency situation.
Problem #5
When using OS/2 Version 2.1 in combination with Novell NetWare,
PKUNZIP cannot re-create lower-level sub-directories when
decompressing a program. (This problem only appears in a global
session.) If you are experiencing these types of problems,
disable sub-directory deletion on the Advanced Options screen of
ZIP'R Pro.
Questions & Answers
Question #1:
Can ZIP'R Pro leave a program uncompressed after it has been
previously compressed with ZIP'R Pro?
Answer:
Yes! Simply use the "Query" option on the program. Before
ZIP'R Pro attempts to recompress the program, it will ask you
if you want to compress it. Answer "No" to the prompt, and the
program will remain uncompressed. Another option is to use the
Compress / Decompress Only option, located on the Advanced ZIF
Options screen. This will quickly compress or decompress your
program (based on its current state), and exit without
attempting to execute or recompress the program.
Question #2:
What networks / multitaskers does ZIP'R Pro recognize?
Answer:
ZIP'R Pro currently recognizes/supports the following operating
systems / environments:
Windows
OS/2
DESQView / DESQview/X
Novell
LANtastic
10Net
Comments From ZIP'R Users
The following list shows samples of some of the comments we have
received on ZIP'R / ZIP'R Pro:
"ZIP'R Pro (is) an archive automator that adds attractive menus,
hotkeys, and help screens. Best of all, you don't need to know a
thing about batch programming to use it."
- Computer Shopper
April 1994
"Works as advertised. Seamless integration.... I think you have a
superb product."
- Toronto, Ontario
"ZIP'R is going to save you money, and more important hard disk
storage space. It will save you money AND headaches by not
having to purchase a disk compression program such as Stacker or
SuperStor.... Support shareware and give this program a try. I
know you will use it, NO ONE ever has enough hard disk space."
- Throughput (The S.W.I.P.C.C. Inc. Journal)
March 1993
"Really neat program."
- Dresden, Tennessee
"There is an excellent interface for setting up each program
within ZIP'R... Once a program has been set up, it's operation
within ZIP'R is transparent to the user. One advantage to those
who can't afford the 40 to 50 K of RAM required by other
compression programs is that ZIP'R only requires 2.5K RAM when it
has finished loading your program. When you have become familiar
with the program you will wonder how you ever managed without
it."
- read.me (The Personal Computer Club of Toronto)
October 1993
"...thanks for a great product."
- Edgewood, New Mexico
"It's (ZIP'R is) a program of professional quality, worth
registering ... It helps me to avoid Double Space..."
- The Netherlands
