5 General Program Description
ZipMaster, hereinafter referred to as ZM, is a powerful, full-
featured ZIP file compression system manager. It is designed to work
with the PKWare file compression system programs PKZIP.EXE,
PKUNZIP.EXE, ZIP2EXE, and PKZIPFIX.EXE. In addition,
support is provided for browsing files with Vernon Buerg's LIST.COM,
virus scanning files with John McAffe's SCAN.EXE, and compressing
executable files with PKWare's PKLITE.EXE (or LZEXE.EXE).
ZM is designed to make navigation of a hard disk and its
attendant directory tree structure a snap. ZM displays the directory
structure of two separate disk drives as a graphic tree, 15
directories per page and all the directories are alphabetically sorted
within tree levels of depth. Through the use of a movable cursor bar,
function, alt, and ctrl key commands, the user may accomplish a great
deal of directory management functions quickly and easily. For
example, directories may be added, deleted, purged, or renamed with
just a few keystrokes. And the auxiliary disk information and file
windows keep the user fully informed as to the current status of the
directory organization.
There's much, much more to ZM. It is very intuitive and quite
easy to use, but it is recommended that the remainder of this document
be perused before running this excellent utility.
6 Program Operation
6.1 Starting ZM
The ZipMaster system includes ZM.EXE and ZM.OVR. The overlay
file, ZM.OVR, must be located in the same directory as ZM and must not
be renamed. The ZM overlay system will use expanded memory if enough
is available, otherwise it will read directly from the ZM.OVR disk
file.
- 6 -
Starting and running ZM is simple. It will accept up to three
command line switches. The acceptable switches are an alphabetical
drive letter and a "-m" switch. If started with no switch, ZM will
operate on the currently active drive. If started with one switch, the
right window of the dual window display will contain the directory
tree for the drive corresponding to the drive letter switch. The left
window will contain the tree for currently active drive. If started
with two switches, the tree for the first switch will appear in the
left window and the tree for second switch will appear in the right
window. If the "-m" switch appears at the end of the command line, ZM
will be forced to start in the monochrome mode. Here are some command
line switch examples:
ZM d drive D in the right window.
ZM e f drive E in the left window, drive F in the right.
ZM e -m drive E in the right window, start in mono
As distributed, ZM is configured to automatically detect and
utilize either monochrome or color monitors. Some monitors, however,
report themselves as color monitors but do not fully support the
standard color attributes. Laptop computers are typical of this
group. If the display problematic for this reason, press Alt+C (or
F11) to activate the ZM configuration window, toggle ZM to the "Force
mono mode", and then save the configuration to disk. The next time ZM
is run, it will go into a monochrome mode, which is much more readable
on a laptop monitor. ZM will recognize and adjust to special monitor
modes that display greater than 25 lines per screen such as the
EGA/VGA 43/50 line mode.
ZM may be operated from any drive:\directory in a system
providing that the directory in which it resides is identified in the
DOS PATH statement. Please see the file PATHINFO.TXT for an
explanation of how to utilize the DOS PATH capability. To exit from
ZM and remain in the directory from which it was loaded, press the Esc
key or press Alt+X. Pressing the Esc key from the dual tree display
to exit affords the user the opportunity to confirm the intention to
quit the program. Alt+X can be used to rapidly terminate ZM from
anywhere in the program.
ZM will search the DOS PATH for copies of PKZIP.EXE and
PKUNZIP.EXE when it initially loads and will not perform ZIP or UNZIP
operations if these respective files are not located.
6.2 Main Display
The main display of ZM is designed to provide the maximum amount
of information without cluttering up the screen. The graphic trees
are displayed in dual windows which occupy left and right sides of the
- 7 -
screen. A solid movable cursor bar appears in the active window and a
cursor place holder marks the active directory in the inactive window.
The cursor bar is moved in the standard PC fashion by pressing the
cursor control keys on the keyboard key pad. Switching windows is
accomplished with right/left arrow keys or the Tab key.
6.3 The Cursor Bar
Operation of ZM is primarily based upon use of the cursor bar in
a "point-and-shoot" manner. The Up/Down arrows, PgUp/PgDn, and
Home/End keys are used to move the cursor. Pressing the Home key
positions the cursor at the first directory on the tree. The End key
moves the cursor to the last directory on the tree. PgUp and PgDn can
be used to page through a tree that has more than twenty directories.
6.4 Mouse Support
ZM will automatically detect the presence of a system mouse
driver and activate the mouse if one is present. The directory tree
cursor bar can be moved by moving the mouse up and down or right and
left. The mouse left button emulates the Enter Key, the right button
emulates the Esc Key, and pressing both left and right buttons
together calls help. The mouse is not active while in the ZM text
editor or during entry of file/directory name information.
6.5 Command Menu
The slash key ("/") activates the main ZM command menu. Most of
the commands described below are available from this menu.
6.6 Function Key Commands
The majority of functions provided by ZM can be accessed via one
of the ten function keys.
F1 - On-line Help
F2 - Directory Data Display
F3 - Change Drive
F4 - Drive Data Display
F5 - Edit Text File
F6 - Rename Directory
F7 - ZIP Current Directory
F8 - ZIP Changed Files
F9 - Recursively ZIP Directory
F10 - Global File Browse
Each of these functions will be explained in greater detail in the
following Paragraphs.
- 8 -
6.6.1 F1 Key
The F1 Key is used to access the on-line context sensitive help
system incorporated into ZM. When pressed while the tree cursor is
active, the main help index will be displayed. If pressed while in
any other ZM function, help for the active function is displayed.
Mouse users may press the LEFT and RIGHT mouse buttons to invoke the
help function.
6.6.2 F2 Key
The F2 key activates a window that contains much interesting
information about the contents of the directory currently under the
cursor bar. This drive information display will show the total number
of files, number of files with hidden/read-only/system attributes, the
largest and smallest files, the oldest and newest files, and other
information.
6.6.3 F3 Key
The F3 key is used to change to another system drive. Any valid
drive in the system may be accessed by simply pressing the letter key
that corresponds to the DOS drive letter. If the selected drive is
not valid or the drive is not ready, an error message will appear in
an error window, otherwise the drive change will be effected and the
directory tree for the selected drive will appear in the active
window.
6.6.4 F4 Key
The F4 key is used to display a window containing information
pertinent to the drive being serviced by the active window.
6.6.5 F5 Key
ZM has a built in text editor that will handle ASCII text files
up to 64K in size. The command structure of the editor is very
similar to Word Star.
A window will appear that prompts for entry of a file name. If
the file exists in the active directory, it will be loaded into the
editor, otherwise the editor will appear with an empty text buffer and
the entered file name will be created when (and if) the editor is
exited using the save (F10) command.
- 9 -
6.6.6 F6 Key
ZM makes it very easy to rename a directory. Pressing the F6 key
will activate a window that will prompt for the new name of the
directory under the cursor bar. Any legal DOS directory name may be
entered. This includes names that contain a period, as in
LONGNAME.DAT. If the entered name is the same as the name of a
directory at the same level, an error window will appear, otherwise
the directory will be renamed. The active tree is resorted after the
renaming of a directory. Of course, the root directory may not be
renamed.
6.6.7 F7 Key
The F7 key is used to invoke PKZIP to compress all files in the
current directory that match the active file name mask. A window will
appear that prompts for the name of the ZIP file. After the file name
has been entered, a window containing the inactive tree will appear
for selection of a target directory in which to place the ZIP file.
6.6.8 F9 Key
Pressing F8 Key invokes PKZIP to automatically compress all files
in the current directory matching the file name mask that have had
their archive bits set indicating the file has been changed or
updated. The mode uses the PKZIP -i switch.
6.6.9 F9 Key
The F9 key is used to recursively ZIP the current directory.
This will invoke PKZIP with the -rp command switch which will cause
PKZIP to compress all files in the current directory and all attached
subdirectories.
6.6.10 F10 Key
The F10 key is used to enter the global browse mode. A window
will appear that prompts for a file mask which will be applied to all
files on the current drive. Using a mask of "*.*" provides fast, easy
access to every file on the active drive.
6.7 Other ZM Commands
ZM provides other important functions through command keys as
described below.
- 10 -
6.7.1 Ins Key
The Ins key is used to invoke the add directory function that
adds a directory to the active tree. A window will appear that
prompts for the name of the directory to be created. It is important
to note the position of the tree cursor bar when invoking this
function. If it is desired to add the directory to the root
directory, then press the Ins key with cursor bar over the root
directory entry. Otherwise, move the cursor bar to the directory
entry that you wish to be the immediate parent of the new directory.
Note that the tree is resorted and redisplayed following the addition
of a directory.
6.7.2 Del Key
Directories may be removed in ZM by pressing the Del key with the
cursor bar over the target directory. The remove directory function
will remove the directory from the active tree. Remember, the
directory must not contain any files or subdirectories or an error
will occur. The active directory will be removed from both the
current drive and tree if the action is successful. The root
directory, of course, may not be removed.
6.7.3 Alt+K Key
You can browse the PKWare ZIP documentation file MANUAL.DOC if
that file is located in a directory that is in the DOS path.
6.7.4 Alt+P Key
ZM provides a fast, powerful method of cleaning up hard disks
through the directory purge function. The entire contents of a
directory may be purged by pressing the Alt+P key combination. Not to
worry, the user must confirm TWICE before the action actually takes
place and it is not possible to purge the root directory while in ZM.
A user might do a lot of damage through negligent use of this
function, so BE CAREFUL! Press the Alt+P key combination with the
tree cursor bar highlighting the target directory. A window will
appear that will issue two separate prompts for user confirmation of
the purging action. Please note that when ZM cleans out a directory,
it takes with it ALL files, regardless of attribute. This means that
hidden, read-only, system files et al will be deleted. After the
purging action, a message informing the user of success or failure
will appear. Directories containing subdirectories may be purged
without effecting the child subdirectories or their contents.
- 11 -
6.7.5 Alt+Z Key
You can browse the ZipMaster documentation file ZM.DOC if indeed
that file is located in a directory that is in the DOS path.
6.7.6 Tab Key
Pressing the Tab key is the same as pressing the left or right
arrow keys. This changes to the inactive tree.
6.7.7 Ctrl+F3 Key
Use the Ctrl+F3 command to send one or more control code strings
to the printer. The control code string(s) must be placed in an ASCII
text file named ZMPRINT.CFG and this file MUST reside in a directory
that is in the DOS PATH. The format of each control code string is as
follows:
\27\38\108\49\50\68\
\12\
Where:
\27 = ESC character
\38 = "&"
\108 = "l"
\49 = "1"
\50 = "2"
\68 = "D"
Note that the backslash character ("\") MUST seperate decimal
values of the individual codes and that the slash MUST appear at both
the start and the end of each string. In the example above, the first
control code string is equivalent to sending 'ESC&l12D' (set line
spacing to 12 lines per inch) to an HP LaserJet or compatible printer.
The second string sends a form feed character (#12) to the printer.
These strings would accomplish the same thing on an Epson printer
(sending 'ESC318' to set a line feed value of 1/12"):
\27\51\49\56\
\12\
Where:
\27 = ESC character
\51 = "3"
\49 = "1"
- 12 -
\56 = "8"
Note that the internal ZM text editor is most useful for
creating\editing the ZMPRINT.CFG text file.
6.7.8 Ctrl+M Key
As distributed, ZM uses a file mask of "*.*" (all files) for
retrieving file names from DOS for display in the file list window.
This default can be changed through the use of the Ctrl+M command. A
window will appear that prompts for entry of the new file mask. Any
valid DOS file mask may be entered. After the mask is changed, only
those files matching the file mask will be displayed in the file list
window. Please note that the total file value that appears on the
window header will still show the total number of "*.*" files in that
directory. Also note that the current file mask setting will be saved
to disk along with the other configurable items when the user elects
to reconfigure ZM. This file mask applies to both the local and global
browse modes.
6.7.9 Ctrl+P Key
A printout of the entire active tree structure is available via
the Ctrl+P Key. Please note that if the attached printer does not
support IBM line drawing characters, the resultant printout will
appear rather garbled. A warning will be issued if ZM detects that
the printer is not ready. This warning can be bypassed in those cases
where the not ready indication is false.
6.7.10 Ctrl+R Key
The Ctrl+R Key is only active in the Shareware distribution
version of ZM. When pressed, Ctrl+R will cause a window to appear
that prompts the user for Registration information. When the form is
complete, the user has the option of printing the form for mailing to
New-Ware.
6.7.11 Ctrl+F5 Key
Press the Ctrl+F5 key combination to temporarily run New-Ware's
ZIP CommentMaster program which must be in the DOS path and named
CE.EXE.
6.7.12 Alt+S Key
In consonance with the design employed in ArcMaster and SCOUT, ZM
employs a directory catalog strategy. This strategy entails the
storage of directory tree information in a small file named NEW-
- 13 -
WARE.X, where X is the drive letter of the stored tree data. These
files will be stored in a single drive:/directory specified by the
user in the ZM configuration menu. If an empty or invalid path is
entered, as in the case of the default as distributed, ZM will rescan
each drive that it accesses. To speed up this operation by using the
catalog file strategy, configure ZM to use a valid drive:/directory
for storage of the catalog files.
Using this strategy greatly speeds up operation of the program
because it is not necessary to scan the entire disk through DOS each
time a drive is accessed. The only drawbacks to this strategy are
minor and are far outweighed by the increased performance. If a
directory is created, renamed, or removed other than by ZM, ArcMaster,
or SCOUT, it will be necessary to re-scan the drive to update the
catalog. This is accomplished by pressing Alt+S. Catalog maintenance
by ZM is mostly automatic and re-scanning should be a rare necessity.
6.7.13 Alt+R Key
The Alt+R key provides a fast method of removing an entire
subtree from the active tree. A double user confirmation is required
before this destructive action is performed. ALL files and ALL
subdirectories attached to the directory under the cursor when Ctrl+R
is pressed will be removed from the active tree and physically from
the active drive. This includes hidden, read-only, or system files,
so BE CAREFUL! Once the action is complete, recovery of file data is
impossible. NOTE!!! Tree removal now starts WITH THE DIRECTORY UNDER
THE CURSOR BAR and proceeds downward through the attached subtree.
This function is inactive if the root directory is highlighted when
Alt+R is pressed.
6.7.14 Alt+T Key
An entire subtree may be transferred from the active to the
inactive tree with the Alt+T command. All files in and all
subdirectories attached to the directory under the cursor bar in the
active tree will be transferred (copied). After selecting a target
drive for the transfer, select a target directory on the target drive
from the presented tree structure. The tree that was selected as the
source, including the directory under the cursor bar will be attached
to the directory under the cursor bar and all files, if any, will be
transferred as well. This is a nondestructive action and the active
tree and drive are left intact.
6.7.15 Setting File Masks
ZM supports file size, date, and name masking. The settings of
the current masks are displayed in the lower left hand corner of the
- 14 -
main screen. These masks are applied any time a file browse mode is
entered. ZM will retrieve only those files whose sizes are greater
than the size mask value and only those files that fall between the
low and high date mask values inclusively. The file name mask is the
standard DOS mask. To set the size mask, use the Ctrl+S key. The
Ctrl+M key will set the file name mask.
6.7.16 Setting PKZIP Date Masks
Use the Ctrl+D key to set the ZIP After date mask and the Alt+D
key to set the ZIP Before date mask. Enter the dates in standard
'MM-DD-YY' format. ZM will abbreviate the entered dates to 'mmddyy'
when they are passed to PKZIP via the -t (After) and the -T (Before)
date switches.
6.7.17 Ctrl+A, Ctrl+E, & Ctrl+Y Keys
The Ctrl+A key activates the built in ZM text editor with the
system AUTOEXEC.BAT file loaded.
The Ctrl+E key activates the ZM text editor and loads the current
master DOS environment. The editor may then be used to alter the
environment as desired. Pressing F10 while in the editor will cause
ZM to replace the current master environment with the current edit
buffer. The amount of DOS environment space is displayed at the
bottom of the ZM edit screen and if the edit buffer size exceeds the
size of the current environment space, the buffer will NOT replace the
environment and an error message will appear.
The Ctrl+Y key activates the editor with the system CONFIG.SYS
file loaded.
6.7.18 Ctrl+V Key
Use the Ctrl+V key or (F12) to invoke McAfee's VirusSCAN program
(SCAN.EXE) to scan all files in the active directory.
6.7.19 "=" Key
The "=" key may be used to quit ZM and change to the
drive:\directory under the active cursor in the process.
6.7.20 Alt+F10 Key
The current ZM memory status may be displayed by pressing the
Alt+F10 key from the main display.
- 15 -
6.8 Alt+C Key
ZM may be configured to suit individual user requirements. Press
the Alt+C key (or F12) to activate the configuration menu. The items
on the menu are toggled back and forth from ON to OFF by moving the
cursor bar to the desired item and pressing the Enter key. The
following items appear on the menu:
6.8.1 Force Mono
Setting this toggle to on will cause ZM to be forced into the
monochrome (two color) mode whenever it loads. This is useful for many
laptop portable displays.
6.8.2 Swap to EMS/Disk
ZM employs a technique of swapping some of its code and data
areas to disk or EMS when shelling out to perform various supported
tasks. This is not needed in systems with 400K or more of RAM
available at runtime, but can be most useful when RAM is tight. When
set to ON, ZM will swap to EMS providing there is enough expanded
memory available to accommodate the swap. If no EMS is available, ZM
will create a temporary swap file in which to hold the swapped code.
6.8.3 Pause After Execution
When this item is set to ON, ZM will pause after the use of
Ctrl+Enter from a browse mode is used to execute a program.
6.8.4 Confirm Before Overwrite
When this item is set to ON, ZM will prompt the user for
overwrite confirmation any time during file copy operations in which a
file overwrite might occur. This also applies to all move operations.
6.8.5 CRC Check
ZM will perform a CRC check during all copy operations when this
item is ON. This means that a CRC value will be generated during the
copy and then the copied file will be read back to generate a second
CRC value. If just one bit of the file data was altered during the
copy operation, the CRC values will not match and ZM will notify the
user of the failure. This also applies move operations across drives.
6.8.6 Use ZIP Menu
ZM will normally always present the PKZIP command/options menu
when the F9 key is used for ZIP operations in a browse mode. Some
- 16 -
users may want to bypass this menu and always use specific command and
a standard set of options. Once options are set in the PKZIP options
menu, they will be saved to the configuration file when along with
other configurable items. If this item is set to OFF, those items
will be invoked automatically and the PKZIP menu will not be displayed
during compression operations.
6.8.7 Use UNZIP Menu
Setting this item to OFF does exactly the same thing as described
above except that it applies to the PKUNZIP command/options menu that
would normally appear after using the F10 key from a browse mode or
while viewing ZIP file contents.
6.8.8 Use Pop-Up Tree
When this item is set to ON, the inactive tree is always
presented in a window for selecting the target drive:\directory for
browse file operations. If set to OFF, this tree is not presented and
the directory under the inactive cursor is used as the destination
directory.
6.8.9 Always Sort Tree
When set to ON, the directory trees are always sorted following a
re-scan and rebuilding of the tree for a specified drive. When set to
OFF, the tree is not sorted. Be sure to use the Alt+S command to re-
scan the disk when changing this item.
6.8.10 New-Ware Catalog File Path
Use this menu item to specifiy a DOS directory path name where ZM
is to maintain the catalog file(s), NEW- WARE.X, for each drive. The
default is no path. If a valid dos drive:\directory path is entered
here, ZM will store and maintain a catalog file for each drive
accessed in this directory. If not, ZM will perform a directory tree
rescan each time a drive is initially accessed.
6.8.11 ZIP Temporary Directory
Entry of a full, valid DOS directory PATH here will cause ZM to
pass the entered PATH to PKZIP with the "-b" switch. This will force
PKZIP temporary files to be stored in the specified directory.
6.8.12 Editor Name
This item permits customizing ZM to use your favorite text editor
from either browse mode. Enter the 8 character name (omit the
- 17 -
.COM/.EXE extenstion). The distribution default name is Sem-Ware's
outstanding QEDIT.
6.8.13 PKLite Options
Use this function to set the desired command line options to
passed when invoking PKLite from PKWare.
6.8.14 Save To ZMCFG.CFG
Press Enter with the cursor bar over this item to save the
configuration set to a disk file name ZMCFG.CFG. Note that all current
PKZIP, PKUNZIP, and PKLITE options will also be saved. This file will
be placed in the same directory as ZM.EXE, providing ZM.EXE resides in
a directory that is on the current DOS PATH. If not, it will be
placed in the active directory. If ZMCFG.CFG is in a directory on the
DOS PATH when ZM.EXE is loaded, ZM will read the file and set
configurable items accordingly.
6.9 Directory Name Search
Some users may have a large number of directories in a graphic
tree for a particular drive. ZM offers a quick method of moving the
cursor to a desired directory name that might be several display pages
down in the tree. If a character key is pressed, ZM will
automatically search through the tree and position the cursor on the
directory name whose first character matches the pressed key. If a
second character key is immediately pressed, ZM continues the search
by searching for directory names that match the two characters.
Subsequent character key presses add to the search string and the
cursor bar is moved each time a new match is found. The currently
active search string is displayed at the bottom of the tree. The
backspace key can be used to delete characters from the string. If
any key other than an alphabetical character or legal directory name
character key is pressed, the search string is cleared.
6.10 File Browse Mode
The ZM file browse mode is active when either the Enter key or
the F10 key (global mode) are pressed. The F10 Key activates the
global browse mode and Enter key activates the local directory browse
mode. Files are displayed in two columns of 21 files per column. All
files matching the active file masks will be listed and a movable
cursor bar is available to browse through the file list. Up/Down
arrow, PgUp/PgDn, Home/End, Ctrl+PgUp/Ctrl+PgDn keys are can be used
to move through the list. Files can be sorted in any one of five ways
and the sort may be changed at any time while in the browse mode. The
Tab Key is used to toggle the direction of the sort to ascending or
- 18 -
descending. The F1 key provides help information on all the commands
available while in the browse mode. Individual files may be LISTed,
edited, SCANed, or executed from the browse mode. In addition,
ArcMaster may be called and passed the file name under the cursor bar.
ZM provides a fast, easy method of finding a file name while in
the browse mode. Pressing any key associated with a legal DOS file
name character will cause ZM to search the entire browse list for a
file name beginning with that character. If it finds one, the cursor
will jump to that file name and the first character typed will appear
on line 23 of the display. ZM will continue the search and build the
search string with each character pressed. The backspace key may be
used to delete characters from the string and the string will be
cleared any time a cursor pad key (Down arrow, PgUp, Home, etc.) is
pressed. This feature works best, of course, when the list is sorted
by name in ascending order.
ZM offers the unique capability to create an ASCII text file that
contains a sorted columnar listing of files. If Ctrl+F is pressed
while in the global browse mode, a text file named ALLDRIVE.ZM is
written into the current directory containing data on all files on the
current drive matching the file mask. If pressed while in the local
browse mode, a text file named THISDIR.ZM is written into the current
directory. Both listings will be sorted according to the sort type
and direction active when Ctrl+F was pressed. This strategy permits
the user to use a favorite editor or word processor to manipulate
and/or print the listing. If either file exists in the current
directory when Ctrl+F is pressed, it will be overwritten.
ZIP file directories may be viewed while in the browse mode. To
view the contents of a ZIP file or an EXE file created with ZIP2EXE,
press ENTER with the cursor bar over the target file. ZM can also
call Buerg's LIST program to view compressed files. Pressing ENTER
with the cursor over a file listed inside a ZIP file will cause ZM to
decompress the file and pass it to list. It is also possible to view
and manipulate, i.e. extract, erase, etc., the contents of a ZIP file
that resides inside a ZIP file.
ZIPped files can be tagged with space bar and PKUNZIP can be
invoked from the ZIP listing mode by pressing the F10 key with one. A
menu will appear that offers PKUNZIP commands and option switches for
operation on the tagged files. After selecting the desired command
and options, a window will appear that contains the inactive tree
structure. Moving the cursor bar to a directory name and pressing
Enter selects the target drive:\directory for the extracted files.
- 19 -
6.11 Browse Mode Display
Data for files matching the current file masks are displayed when
the browse mode is entered. The local browse mode (Enter key) shows
only data for files located in the current directory. The global
browse mode (F10) shows data for files located on the current drive.
File data is displayed in two columns. The length of the columns
depends upon the number of display lines available. Each column will
contain 21 lines when using a normal 25 line display.
The top line of the browse display shows the current file name
mask and directory on the left and the number of tagged bytes on the
right. The bottom line of the display shows the file number, total
number of files, page number, total pages, number of files tagged,
current sort type and sort direction. Note that in the Global
display, the top left line will show the parent directory of the file
under the cursor bar.
An example of a file data line is:
FILE EXT 194K 06-15-88 01:22 «
Note that the file size is given in Kilobytes and that a file
with a size of 25,697 bytes will show 26K. Also note that the file
time is given in 24 hour Greenwich format. A small left caret symbol
at the end of the data line indicates that the file's attribute bit is
set.
The left side of the browse display contains a slider bar and a
slider that indicates the relative position of the cursor in the file
list. For example, if the cursor bar is highlighting a file that is
25 percent down the file list, the slider will appear approximately
one- quarter of the way down the slider bar.
6.12 Browse Mode Commands
ZM provides a set of useful and powerful commands that can be
invoked while in either browse mode. Most commands are designed to
act on the set of files designated by the user via the tagging
operation. Files are tagged for processing by pressing the space bar
with the cursor over a file name. The core of this command set
involves invoking PKZIP and/or PKUNZIP to manipulate the ZIP archive
system.
6.12.1 F1 Key
The F1 key displays the browse command list.
- 20 -
6.12.2 F2 Through F6 Keys
Files may be sorted in one of five different ways by pressing one
of the F2 through F6 keys. The key assignments are:
F2 - Sort by Name
F3 - Sort by Extension
F4 - Sort by Name/Extension
F5 - Sort by Date
F6 - Sort by Size
The direction of the sort, ascending or descending, is toggled
via the Tab key. The active sort and direction appears on the bottom
line of the browse display.
6.12.3 F7 Key
The file list of the directory active on the inactive tree may be
rapidly switched to by pressing the F7 key. This key is like a toggle
in that each time it is pressed it switches the display to the
opposite list. The current cursor position is preserved during the
switch.
6.12.4 F8 Key
The F8 key is used to call the ZM text editor. The editor will
attempt to load the file under the cursor bar. The file will not be
loaded if it exceeds 63K in size.
6.12.5 F9 Key
The F9 key is used to commence all operations that involve
compression of files with PKZIP.EXE. If no files are tagged when this
key is pressed, the file under the cursor is automatically tagged.
Selection of the target drive and destination directory for the
resultant ZIP file occur first. Then window that prompts for the name
of the ZIP file to be created or operated on appears first. After
entry of a legal eight character file name, The PKZIP command menu
appears. Options that also affect the operation of PKZIP can be
selected via the "-o" item on this menu. When the desired options
have been selected, press Enter with the cursor over the desired PKZIP
command. ZM will then build the proper command line and pass it to
PKZIP for the operation.
6.12.6 F10 Key
The F10 Key initiates all operations performed on .ZIP and ZIP
self-extracting .EXE files by PKUNZIP. This command is available in
- 21 -
both browse modes and from the ZIP file view mode. A menu appears
that offers a choice of PKUNZIP commands plus submenus through which
more detailed PKUNZIP options are available. Individual or tagged .ZIP
files can also be converted to self-extracting .EXE files through this
menu. PKZIPFIX may also be invoked via this menu. Since operations
on tagged files within a ZIP file differ from those performed directly
upon ZIP files, items on the menu that appears when F10 is pressed
while viewing the contents of a ZIP file are disabled.
The last item on the PKUNZIP command menu is not directly
supported by PKUNZIP. Selecting the "-l" command will cause ZM to
test each tagged file but instead of the PKUNZIP test results being
displayed on the screen, the output is redirected to an ASCII text
file named ZIPTEST.LOG. This file will be overwritten each time the
"-l" switch is used and will be placed in the currently active
directory.
Note that if a PKUNZIP command is selected that entails
extraction of files, the opportunity to select a target drive and
destination directory on that drive will be presented.
6.12.7 "*" Key
The "*" key is used to quickly reset the file mask to "*.*" while
in either the local or global browse mode.
6.12.8 "/" Key
The "/" key brings up a menu that contains all the file browse
mode commands.
6.12.9 Enter Key
Pressing the Enter key while in the browse mode will have
different results, depending upon the type of file under the cursor
bar at the time the key is pressed. If the file is ZIP file or a ZIP
self-extracting EXE file, the ZIP view mode will be entered.
Otherwise, Buerg's LIST program will be called and passed the name of
the file under the cursor for viewing.
6.12.10 Ctrl+Enter Key
A an executable (.COM, .EXE, or .BAT) file may be run from ZM by
pressing the Ctrl+Enter key with the cursor bar over the file to be
executed. To run an executable file and pass it a command line
parameter, use the Ctrl+X key in lieu of Ctrl+Enter
- 22 -
6.12.11 Del Key
Tagged files may be deleted through the use of the Del key. When
the Del key is pressed, the screen clears and a list of tagged files
appears. A confirmation prompt is issued from the top line of the
display. If confirmed by the user, all tagged files are deleted.
System, read-only, and hidden files are not deleted unless
individually confirmed by the user.
6.12.12 Ins Key
Any individual file may be renamed via the Ins key. A window
will appear that prompts for entry of the new file name. Entry of a
valid DOS filename that does not already exist in the target file's
resident directory will result in renaming of the file.
6.12.13 Alt+F1 Key
ZM has a powerful duplicate file find capability. ZM will
display list of duplicate files when the Alt+F1 key is pressed. If ZM
is in the local browse mode, the auxilliary tree window will appear to
allow selection of a directory on the drive displayed in the inactive
window. If ZM is in the global browse mode, files on the active drive
are compared with those on the inactive drive. If the same drives
and/or directories are selected, nothing will happen. Otherwise, ZM
will display a list of duplicate files. Please note that the files
listed are for the currently active drive or drive:\directory and NOT
those found on the other drive or drive:\directory. The duplicates
can be tagged for copying, moving, or deletion and the action will
take place on those files in the currently active window.
6.12.14 Alt+C Key
ZM provides a powerful batch copy mode. When the Alt+C key (or
F11) is pressed, a window containing the inactive directory tree is
presented. The target drive:\directory is selected from the tree by
pressing Enter with the cursor over the target directory. The screen
will clear and a list of all tagged files is presented. If the user
confirms the copy operation, all tagged files are copied to the target
directory. If the Confirm Overwrite toggle is ON, ZM will issue a
request for confirmation before overwriting any existing file. If the
Check CRC toggle is ON, a CRC check is made on each file as it is
copied.
6.12.15 Alt+K Key
If the PKWare file MANUAL.DOC is in a directory that is in the
DOS path, ZM will load the file browser with MANUAL.DOC.
- 23 -
6.12.16 Alt+M Key
The Alt+M key (or F12) works exactly the same as the Alt+C
command described above except that files are moved to the destination
rather than being copied. If the move is across drives, ZM will first
copy the file to its destination and then delete it.
6.12.17 Alt+V Key
McAfee's VirusSCAN can be applied to tagged ZIP files by pressing
the Alt+V key. ZM will create a temporary directory into which to
unZIP each tagged ZIP file. After each file is unZIPped, SCAN is
called to scan all files in the temporary directory. After the SCAN
operation, the files are deleted from the temporary directory and
after all tagged ZIP files are processed, the temporary directory is
removed. Note that SCAN is invoked with the /NOMEM switch for faster
operation.
6.12.18 Alt+Z Key
If the ZipMaster file ZM.DOC is in a directory that is in the DOS
path, ZM will load the browser with ZM.DOC.
6.12.19 Ctrl+A Key
The Ctrl+A key permits changing a file's attribute. A menu will
appear that allows changing the attribute of the file under the
cursor. A file's archive bit may also be toggled from this menu.
6.12.20 Ctrl+F Key
This is a most unusual and quite useful feature. Pressing the
Ctrl+F key results in the creation of an ASCII text file that contains
a listing of files. The name, content, and format of this file
depends upon which browse mode is active when Ctrl+F is pressed. If
in the local mode, the file contains a two-column sorted list of files
in the directory being browsed. If in the global mode, the file
contains a directories on the active drive, with the files in each
directory listed under the parent directory name in two-column sorted
format. The sort used is the one active at the time Ctrl+F is
pressed. The file is stored in the active directory and is named
THISDIR.ZM if in the local mode and ALLDIRS.ZM if in the global mode.
6.12.21 Ctrl+L/Alt+L Keys
Use of the Ctrl+L key requires that two non-PKware programs be
available via the DOS PATH. One is LZEXE, the popular utility that
compresses executable programs and leaves them in executable form. The
- 24 -
other is LZESHELL, which acts as an interpretive shell for the French
LZEXE program. Press Ctrl+L with the cursor bar over an .EXE file to
invoke LZESHELL and LZEXE. The Alt+L key key may be used when
LZESHELL.EXE is not present, since it directly invokes LZEXE.
6.12.22 Ctrl+M Key
Pressing the Ctrl+M key will call New-Ware's ArcMaster and pass
it the name of the file under the cursor bar.
6.12.23 Ctrl+Q Key
The Ctrl+Q key will call the text editor named on the ZM config
menu and pass it the file name under the cursor bar.
6.12.24 Ctrl+T & Ctrl+U Keys
Ctrl+T tags all file in the browse list and Ctrl+U untags all
file in the browse list. The number of files that may be tagged at
one time is equal to the total number of files in the current list.
For example, if the number of files matching the current file mask is
148, then you may tag all 148 files with Ctrl+T and untage all 148
taged files with Ctrl+U.
6.12.25 Ctrl+V Key
Use the Ctrl+V key to invoke McAfee's VirusSCAN program
(SCAN.EXE) to scan the file under the cursor for viruses.
6.12.26 Ctrl+Z Key
This command will invoke PKLITE.EXE, which must be in the DOS
path, to compress the EXE file under the cursor bar. The -b switch is
used so that after compressing the EXE file, PKLITE will leave a copy
of the original file with an extension of .BAK. For example, if you
press Ctrl+Z with the cursor bar over a file named TARGET.EXE, PKLITE
will compress TARGET.EXE and will leave the original EXE file named as
TARGET.BAK.
6.12.27 Tab Key
The Tab key toggles between ascending and descending sorting.
6.13 Browsing A Zip File Directory
Pressing the Enter key, while in either browse mode, with the
cursor bar highlighting a ZIP file (or a ZIP SFX EXE file) results in
the display of the contents of that file. A file in this list may be
- 25 -
selected for browsing with Buerg's LIST by pressing Enter with the
cursor bar over the file. Files may be tagged with the space and
submitted to PKUNZIP for operations via the F10 key. File lines with
an asterisk ("*") at the end denote that a DOS path name is stored
with that file. The path name can be viewed on the bottom line of the
display by pressing the F5 key. Ctrl+P will send a listing of the ZIP
directory to the printer. The Esc key terminates the ZIP browse mode
and returns to the original browse mode.
The contents of a ZIP file inside a ZIP file may be browsed and
manipulated, but the contents of the second or third level ZIP file
cannot be accessed.
6.14 Notes On PKZIP/PKUNZIP Command/Option Menus
Users will note that very little explanatory material relating to
the functions of the various PKZIP and PKUNZIP commands and options is
included here. Users of ZM are encouraged to read MANUAL.DOC and
ADDENDUM.DOC, which are included in the PKware version 1.10 package.
Also note that the programs PKZIP.EXE, PKUNZIP.EXE, ZIP2EXE.EXE, and
PKZIPFIX.EXE are all copyright and trademarked by PKware.
7 Program Limitations
The amount of memory required by ZM depends upon whether or not
the "Swap to DISK\EMS" switch is on or off. If ZM detects that not
enough memory is available to support file manipulation operations
with the switch off, it will automatically turn it on. If more files
are found upon entry into the browse mode than current memory
available will support, ZM will issue an error message to that effect.
If not enough memory is available at runtime for ZM to perform basic
initialization functions, the program will abort at the DOS command
line with a message to that effect. In a system with 570K of DOS RAM
available at runtime, ZM is capable of browsing a list of over 11,000
files with swapping to EMS/DISK disabled and nearly 14,000 files with
swapping enabled. This number will be reduced accordingly as the
amount of available RAM is decreased. Pressing the Alt+F10 key from
the main screen will display the current ZM memory status.
ZM supports version 1.10 of the PKware PKZIP/PKUNZIP file
compression system. The maximum limit of files within a ZIP file is
2000. The actual limit will depend upon the amount of RAM available
at runtime.
ZM supports up to 500 directories per drive. A warning message
will be displayed if the number of files ZM can handle is exceeded.

Please note that if a drive is searched using the global file
specification of "*.*" and the number of files on the drive exceeds
memory capacity, ZM will terminate the find function before all files
on the disk are placed on the list. Similarly, in the unlikely event
that ZM is used on a drive that contains more than 500 directories,
not all available directories will appear on the tree. Both of these
limitations are quite reasonable and should not hinder the majority of
users from exploiting the full power of ZipMaster.
If the swap to EMS/DISK option is set to ON and EMS is not
available, ZM will use a temporary swap file named ZMSWAP.$$$ which
will be placed in the directory from in which ZM.EXE resides. This
file is marked system/read-only and will be deleted after each use.
ZM will use a temporary response file to pass to PKZIP and unzip.
This file is named ZMRESP.$$$ and will be placed in the directory in
which ZM.EXE resides and is deleted after each use.
The graphic tree printout functions sends IBM line drawing
characters to the printer. Some printers do not directly support
these characters and may substitute non-line characters thus reducing
the quality of the resultant printout.
The width of the window that contains the graphic tree display is
great enough to support at least 5 levels of directories with each
directory name eight characters in length. Directory tree levels
greater than five with extended length names may overrun the right
edge of the display.
8 Error Handling
ZM incorporates extensive error handling. DOS critical errors
such as "Drive not ready" and "Attempt to write to a write-protected
disk" are trapped and displayed to the user. Any time ZM cannot
perform a commanded function it will pop-up a window that informs the
user of the nature of the error. Normal program operation then
continues. If a fatal error occurs that prevents continuation of
normal program operation, a special error window will appear that
explains the nature of the error and then ZM will be terminated.
Please report fatal errors to New-Ware.

9 Credits
Special thanks to Dave Hardy in San Francisco for his excellent
beta test support and many constructive suggestions.
Please note that all the supported programs MUST reside in a
directory that is identified in the DOS PATH. Users not familiar with
how the DOS PATH works are urged to read PATHINFO.TXT that is supplied
in the ZM Shareware package.
ZM employs special code swapping software developed by Kim
Kokkonen of TurboPower Software. This unit permits ZM to swap most of
its resident code to expanded memory (EMS) or to disk when shelling
out to call external programs such as LIST or QEDIT. If sufficient
EMS memory is available for the swap, the swap will be almost
instantaneous. If no EMS is available, the swap will be made to a
temporary disk file named ZMSWAP.$$$. In this case there will be a
noticeable delay during the swap, especially if operating on a slow
hard disk. It is recommended that swapping be kept OFF unless
adequate EMS memory (380K+) is available for swapping or a very fast
hard disk system is in use.
New-Ware strongly recommends Sammy Mitchell's (Sem-Ware)
outstanding text editor QEDIT. ZM supports calling QEDIT to edit
files on the browse list if a copy of QEDIT resides in a directory
that is identified in the DOS PATH.
ZM supports LISTing files with Vernon Buerg's famous LIST
program. LIST must reside in a directory that is identified in the DOS
PATH.
ZM supports scanning full directories or selected files using
John McAfee's VirusSCAN program. SCAN must be named SCAN.EXE and
exist on the DOS PATH.
ZM supports compressing or decompressing selected files using
PKWare's PKZIP and PKUNZIP. These files must be named PKZIP.EXE and
PKUNZIP.EXE and reside on the DOS PATH.
ZM supports invocation of Pete Petrakis' free utility, LZESHELL
version 3.0. LZESHELL is the ideal companion for LZEXE, which is a
marvelous utility that compresses .EXE and converted .COM files and
allows them to be executed in compressed form. Be sure to read
LZESHELL.DOC for further information.

ZM also supports calling New-Ware's ArcMaster and passing it a
specified file name. ArcMaster must be named AM.EXE and reside on the
DOS PATH.
QEDIT, LIST, PKZIP, and SCAN are all Shareware products. New-
Ware urges that those who use these products register them with their
respective authors.
TurboPower Software provides outstanding support for Turbo Pascal
programmers. New-Ware strongly recommends TurboPower products to all
Pascal users, especially their TPro 5.0 Professional and Object
Professional 1.0 packages.
