ΓòÉΓòÉΓòÉ 2. PMZIP Overview ΓòÉΓòÉΓòÉ
ZIP files contain other files. Typically the files in a ZIP file are
compressed. ZIP files make it easy to group files and makes transporting and
copying these files faster.
PMZIP(TM) is a ZIP file manager for the OS/2 Presentation Manager. It provides
an easy-to-use SAA/CUA compatible interface for quickly adding, deleting,
extracting, and viewing members of a ZIP file. The program is easy to install,
and extensive online help is always available.
The main PMZIP window includes a list of files in the open ZIP file. This list
can be scrolled and sorted by name, extension, date, or size. Files can be
added, deleted, extracted, or viewed using pull-down menu entries and push
buttons.
Other features include a built-in file search facility that makes it easy to
locate ZIP files anywhere on your disk, support for the File Manager's drag and
drop interface to conveniently add files to a ZIP file, and the ability to save
and restore all options, including screen size and position.
PMZIP supports the CUA "object-action process sequence" philosophy. This allows
you to select objects (files you want to add to a ZIP or files already in a
ZIP) and then specify the action you want to perform. Alternately, you can use
PMZIP in a more traditional "action-object" style of interaction.
The most common ways to start the program are:
o To open an existing ZIP file from the File Manager, double click on the ZIP
file.
o To add files to an existing ZIP file, use the technique described in the
section titled Drag and Drop Interface. Briefly, select one or more files
in the File Manager, hold down mouse button two, drag the file(s) over a
PMZIP window or icon, and release the mouse button. NOTE: you should drop
files over a copy of PMZIP that is running, not over an icon in a Desktop
Manager Program Group window.
o To add files to a new ZIP file, use the procedure for adding files to an
existing ZIP file, but be sure to specify the name of a ZIP file in the
dialog box displayed when you "drop" files onto a running copy of PMZIP.
You can also start PMZIP by double clicking on the PMZIP icon in the "Group -
Main" window. To start PMZIP from the OS/2 command line type PMZIP,
optionally specifying the name of a ZIP file as the first and only parameter.

ΓòÉΓòÉΓòÉ 5. Quick start information ΓòÉΓòÉΓòÉ
Many people that have used other Presentation Manager or Windows applications
will be able to use PMZIP without reading all the documentation. However, the
following sections should be reviewed before running the program:
o Copyright/License Agreement/Warranty
o Installation
o Drag and Drop Interface
I also suggest you read the section titled Notes for miscellaneous information
about the interface philosophy and background, as well as technical notes.
For more information about using the help facility, select Help for help on
the Help pull-down.
ΓòÉΓòÉΓòÉ 6. Drag and Drop interface ΓòÉΓòÉΓòÉ
PMZIP supports the File Manager's "Drag and Drop" interface in OS/2 version
1.20 and later. This interface provides a convenient way to add, freshen, or
update files in a ZIP file with selected files listed by the File Manager. To
use the interface
1. select one or more files in the File Manager
2. hold down mouse button two
3. drag the file(s) over PMZIP window or icon
4. release mouse button two to drop the file(s)
NOTE: you should drop files over a copy of PMZIP that is running, not over an
icon in a Desktop Manager Program Group window.
When you drop one or more files on a PMZIP window, the "Drop" dialog box is
displayed. The dialog box lets you change the name of ZIP file affected by
the drop operation, either by typing the name of a ZIP file, or by clicking on
the Open or New buttons, which activate the standard Open and New dialog
boxes, respectively. This is a quick way to open a different ZIP file without
going through the File pull-down menu.
The Drop dialog box provides the following options:
o The Add, Freshen, and Update radio buttons correspond to the PKZIP -a, -f,
and -u options
o The "delete original after adding" check box corresponds to the PKZIP -m
option
o The Size and Speed radio buttons correspond to the PKZIP -ex and -es options
o The "Recurse subdirectories" check box corresponds to the PKZIP -r option
o The "Store recursed pathnames" check box corresponds to the PKZIP -p option
o The "Store specified pathnames" check box corresponds to the PKZIP -P option
ΓòÉΓòÉΓòÉ 7. Installation ΓòÉΓòÉΓòÉ
System Requirements:
o OS/2 version 1.2 or later.
o The OS/2 versions of the PKWARE, Inc. PKZIP(TM) and PKUNZIP(TM) programs.
These can be obtained from most bulletin board systems or ordered directly
from PKWARE (phone 414-352-3670).
PMZIP-related files are:
o README.1ST this file
o ORDER.DOC order form
o PMZIP.EXE executable
o PMZIP.HLP documentation in online hypertext help format
o PMZIP.TXT documentation formatted for printing
o PMZIP.DLL required dynamic link library
Installation:
There are two parts to the installation process. The first is performed
manually before running PMZIP. The second part is run from the Install dialog.
This dialog box is displayed the first time PMZIP is run, and can be rerun
from the Options pull-down menu.
One time installation procedure:
1) If you already have installed a previous version of PMZIP, delete all files
in your PMZIP directory. Otherwise create a directory to hold the PMZIP
related files. For example, "C:\PMZIP".
2) Copy all PMZIP-related files to this directory. At a minimum you need the
following files: PMZIP.EXE, PMZIP.HLP, and PMZIP.DLL. Note: there is no need
to include the directory containing PMZIP related files in your LIBPATH= or
HELP= paths.
3) Run PMZIP.EXE, either by double clicking on PMZIP.EXE in the File Manager
or by entering PMZIP at the the OS/2 system prompt. The first time you run
PMZIP it will bring up the Install dialog box to complete the installation.
If PMZIP cannot find PKZIP or PKUNZIP in your path, it will prompt you for the
program locations with the Program locations dialog box.
Optional steps:
a) Add the directory created in step one to your PATH. If you don't add the
directory to your path, you'll need to type the directory name when you start
PMZIP from the command line (for example, you'll have to type "C:\PMZIP\PMZIP"
rather than just "PMZIP").
b) Add the statement PMZIP /ICON to your STARTUP.CMD file. This will
automatically start PMZIP as an icon whenever you boot OS/2, and facilitates
use of the File Manager's Drag and Drop Interface.
Install dialog box:
The Install dialog box will add a PMZIP entry to the first Program Group in
the Desktop Manager (usually "Group - Main"). It will also set a File Manager
association for *.ZIP files. This association lets you double-click on any
ZIP file listed in the File Manager to automatically open the ZIP file with
PMZIP.
ΓòÉΓòÉΓòÉ 8. Program locations ΓòÉΓòÉΓòÉ
The Program Locations dialog box is displayed during PMZIP initialization if it
can't find the OS/2 versions of the PKZIP or PKUNZIP commands. If this dialog
box is displayed, type the name of the programs in the appropriate entry fields
and click on the OK button. Specify either a fully qualified pathname (e.g.
C:\PKWARE\PKZIP.EXE), or, if you want PMZIP to search your path, just the
filename and extension (e.g. PKZIP2.EXE).
Note: PKWARE distributes the OS/2 versions of their products with a "2" or "F"
file name suffix (e.g. PKZIP2). Since many users rename the files to remove
these suffixes, PMZIP automatically searches for all three file name formats
when it is first installed.
ΓòÉΓòÉΓòÉ 9. Opening ZIP files ΓòÉΓòÉΓòÉ
You can open ZIP files with the standard "New" or "Open" entries on the File
pull-down menu. These functions work like those of most other PM applications,
except that the Open dialog box features a File Search Facility that will list
all or selected ZIP files in your directory tree.
Alternately, you can open a ZIP file while using the File Manager's "Drag and
Drop" interface to add files to a new or existing ZIP file, as described in the
section titled Drag and Drop Interface. If you change the name of the ZIP file
in the Drag and Drop dialog box, then PMZIP will continue to work with the
specified ZIP file until you again change the name.
To save mouse clicks, PMZIP automatically brings up the Open dialog box if no
ZIP file is specified when the program is started. To disable this behavior,
click on the "Auto open dialog box" radio button in the Configuration dialog
box and save the default settings via the Defaults dialog box.
You can close the current ZIP file with the "Close" entry on the File pull-down
menu. However, this menu entry is included primarily for completeness, since
the New, Open, and Drag and Drop dialog boxes all automatically perform this
action.
ΓòÉΓòÉΓòÉ 10. Adding files to a ZIP file ΓòÉΓòÉΓòÉ
There are two ways to add files to a ZIP:
1) Object-action interface: use the File Managers "Drag and Drop" interface,
as described in the section titled Drag and Drop Interface.
2) Action-object interface: click on the "Add" push button or select the "Add"
entry from the "Action" pull-down menu to bring up the Add dialog box. Then
specify the file names you want to add (standard OS/2 wildcards are accepted).
The Add dialog box provides the following options:
o The Add, Freshen, and Update radio buttons correspond to the PKZIP -a, -f,
and -u options
o The "delete original after adding" check box corresponds to the PKZIP -m
option
o The Size and Speed radio buttons correspond to the PKZIP -ex and -es options
o The "Recurse subdirectories" check box corresponds to the PKZIP -r option
o The "Store recursed pathnames" check box corresponds to the PKZIP -p option
o The "Store specified pathnames" check box corresponds to the PKZIP -P option
ΓòÉΓòÉΓòÉ 11. Deleting files from a ZIP file ΓòÉΓòÉΓòÉ
There are two ways to delete files from a ZIP:
1) Object-action interface: first select entries in the list box, then click
on the "Delete" push button or select the "Delete" entry from the "Action"
pull-down menu.
2) Action-object interface: click on the "Delete" push button or select the
"Delete" entry from the "Action" pull-down to bring up the "Delete" dialog box.
You can then specify the file names you want to delete (standard OS/2 wildcards
are accepted).
ΓòÉΓòÉΓòÉ 12. Extracting files from a ZIP file ΓòÉΓòÉΓòÉ
There are two ways to extract files from a ZIP:
1) Object-action interface: first select entries in the list box, then click
on the "Extract" push button or select the "Extract" entry from the "Action"
pull-down menu to bring up the Extract dialog box.
2) Action-object interface: click on the "Extract" push button or select the
"Extract" entry from the "Action" pull-down to bring up the Extract dialog box.
You can then specify the file names you want to extract (standard OS/2
wildcards are accepted) or extract all files in the ZIP.
The Extract dialog box lets you specify the directory to contain the extracted
files (note: the default directory for this prompt can be changed by selecting
"Extract Directory..." in the "Options" pull-down menu).
The Extract dialog box provides the following options:
o The "Overlay newer files only" check box corresponds to the PKUNZIP -n
option
o The "Use pathnames" check box corresponds to the PKUNZIP -d option
Note: the PKUNZIP -o option is always specified.
ΓòÉΓòÉΓòÉ 13. Viewing files in a ZIP file ΓòÉΓòÉΓòÉ
The View dialog box is used to view files in a ZIP file or view the results of
the last PKZIP or PKUNZIP command issued by PMZIP. Unlike most dialog boxes,
the View dialog box is sizeable and can be maximized.
There are three ways to view files in a ZIP file:
1) Double click on a file name in the list box listing files in the ZIP file.
2) Object-action interface: first select entries in the list box, then click
on the View push button or select the "View" entry from the "Action" pull-down
menu.
3) Action-object interface: click on the "View" push button or select the
"View" entry from the "Action" pull-down to bring up the View dialog box. You
can then specify the file name you want to view.
Click on the Clipboard Copy push button to copy selected text to the system
clipboard. Note: this button is disabled when no text is selected.
ΓòÉΓòÉΓòÉ 14. File Search Facility ΓòÉΓòÉΓòÉ
The File Search Facility is invoked by clicking on the Search button in the
Open dialog box. Type a file name (standard OS/2 wildcards are accepted) in
the Pattern entry field of the Search dialog box and click on the Search button
to search an entire disk for the specified file(s). You can then select any
file found by this procedure and click on the Open button to open the ZIP file.
ΓòÉΓòÉΓòÉ 15. Options ΓòÉΓòÉΓòÉ
The PMZIP option system consists of the following components:
The Option pull-down menu lets you specify whether the list of files in the ZIP
file is sorted by date, extension, size, name, or whether the original ZIP file
order should be used. It also lets you bring up the following dialog boxes
described below.
The Configuration dialog box lets you specify
o Whether the default directory in the Extract dialog box is the current
directory or a directory of your choice.
o Whether the Open dialog box is automatically displayed when no ZIP file is
specified when PMZIP is started.
o Whether files in the ZIP file are listed in lowercase for the possibility of
improved legibility.
o Whether PMZIP should maintain a log of all error messages and all PKZIP and
PKUNZIP commands it issues. The log is written to the file C:\PMZIP.LOG.
o Whether PMZIP automatically changes the current directory when files are
dropped to the directory containing the files being dropped.
The Defaults dialog box lets you save the current defaults for use next time
PMZIP is started, or restore the original distribution defaults. Options that
are saved and restored by this procedure include all the options in the
"Options" pull-down menu, all options in the Add, Configuration, Extract, and
Program Locations dialog boxes, and the current screen size. Note that this
information is also saved if PMZIP is running when you select "Save" from the
"Desktop" pull-down in the "Desktop Manager" window.
The Install dialog box will add a PMZIP entry to the first Program Group in
the Desktop Manager (usually "Group - Main"). It will also set a File Manager
association for *.ZIP files. This association lets you double-click on any
ZIP file listed in the File Manager to automatically open the ZIP file with
PMZIP.
The Program locations dialog box lets you specify the file names used by PMZIP
instead of the default PKZIP.EXE and PKUNZIP.EXE.
The View last output entry in the Options pull-down displays the results of
the last PKZIP or PKUNZIP command issued by PMZIP.
ΓòÉΓòÉΓòÉ 16. Error Handling ΓòÉΓòÉΓòÉ
When a PKZIP or PKUNZIP command issued by PMZIP returns a non-zero error level,
a dialog box is displayed listing the error level and error level description.
You can click on the "View command output" button to view all messages issued
by the command that caused the error.
PMZIP will optionally maintain a log of all error messages and all PKZIP and
PKUNZIP commands it issues. The log is written to the file C:\PMZIP.LOG.
Note: When a critical error (e.g. an open drive door) occurs while the PKZIP
or PKUNZIP commands are running, you will get the standard OS/2 error screen.
This is because the PKZIP and PKUNZIP commands were not coded to handle these
errors. PMZIP cannot control this behavior.
ΓòÉΓòÉΓòÉ 17. File Manager hints ΓòÉΓòÉΓòÉ
The OS/2 File Manager isn't the most versatile file management program, but it
is the only one available for OS/2 with a Presentation Manager interface. The
best way to learn to use it is to experiment and read the online help.
Pull-down all the menus, and if you don't know what an entry does, select it
and press the F1 key for context sensitive help (note: if you're using the
mouse, be sure to press F1 while holding down the mouse button).
Here are two hints for using the File Manager. Your suggestions for additional
hints are welcome.
1) By default the file manager does not list file sizes and modification dates.
You can change this by selecting "File details" from the "View" pull-down menu.
To automatically list files by date select "Sort by" from the "View" menu and
click on "Last modification date" in the "Sort by" dialog box and check the
"Set system default" button before closing the dialog box.
2) To open directories in the File Manager's tree display, double click on the
name, not the icon. Clicking on the icon can expand or collapse a branch of
the tree, depending on whether there is a plus or minus sign in the directory
icon.
ΓòÉΓòÉΓòÉ 18. Keyboard usage ΓòÉΓòÉΓòÉ
PMZIP is easier to use with a mouse, but you can also use the standard PM
keyboard interface. The Drag and Drop interface to the File Manager is not
available from the keyboard. Keyboard accelerators defined for PMZIP include:
Ctrl+N Open new Zip file.
Ctrl+O Open existing ZIP file.
Ctrl+A Add files to a ZIP file.
Ctrl+D Delete files from a ZIP file.
Ctrl+E Extract files from a ZIP file.
Ctrl+V View files in a ZIP file.
ΓòÉΓòÉΓòÉ 19. Future Enhancements ΓòÉΓòÉΓòÉ
Ideas for future enhancements include:
o Support for all ZIP options, including passwords and comments
o Ability to run programs in a ZIP file
o Support for other file formats (e.g. ARC)
o Optional hex dump mode when viewing files in a ZIP File
Additional suggestions are welcome!
ΓòÉΓòÉΓòÉ 20. Notes ΓòÉΓòÉΓòÉ
o This version of PMZIP was tested under OS/2 versions 1.20 and 1.30 with
PKZIP and PKUNZIP versions 1.01.
o PKZIP and PKUNZIP are registered trademarks of PKWARE, Inc.
o PMZIP does not manipulate ZIP files directly. Instead it runs PKZIP and
PKUNZIP for all operations.
o PMZIP displays an hour-glass pointer to indicate that it is busy while the
PKZIP and PKUNZIP commands are running. You can, of course, switch to
another OS/2 session during this time.
o PMZIP supports most commonly used PKZIP and PKUNZIP options but the current
version does not include special support for comments, passwords, and file
attribute masks.
o PMZIP will try to use the "System Monospaced" font (the file SYSMONO.FON)
first introduced in the November, 1989 update to OS/2 1.2. If this font is
not found it will use the standard Courier font. The Courier font is always
used for the text in the View dialog box because of a bug in some versions
of OS/2 1.20.
o PMZIP sometimes passes a temporary "list file" to the PKWARE, Inc. programs.
PMZIP uses a unique filename for this file, and automatically erases it when
it is no longer needed. If you have a TMP= environment variable, temporary
files are created in the specified directory. Otherwise they are created in
the root directory of your C: drive.
o Ideally PMZIP should use the same selection techniques as the File Manager
for manipulating files in a ZIP file. However, that facility is not
currently provided by the Presentation Manager, and is quite time consuming
to program from scratch. Since Windows 3.0 provides this facility as a
"Extended Selection List Box", we can hope it will be provided in the
Presentation Manager in the near future, in which case I expect to use it in
PMZIP. Meanwhile, the program uses the standard "Multiple Selection List
Box", which, while not the ideal solution, should be familiar and easy to
use.
o PMZIP was written because I wanted a PM interface to ZIP files, and no other
programs provided this facility. The first version was written in
Digitalk's Smalltalk V/PM. The result, like all V/PM programs, required
over a megabyte of code to execute, and was rather slow. Favorable response
to the first version convinced me to rewrite the program in C and release it
as Shareware.
o Special thanks to Steve Queen for his feedback on the PMZIP user interface.
