Creating A New Zip File
Creating a New .ZIP File

You can create new .ZIP files in the following ways:

•	Using the Windows drag and drop feature.

•	Using the Windows Explorer.

•	Selecting File from the PKZIP for Windows Menu bar and New from the File menu.

•	Using the Tool bar button.


Drag and Drop

PKZIP for Windows allows you to create .ZIP files by “dragging and dropping” files using the Windows File Manager or Windows Explorer.  This method gives you a quick and easy way to compress files.  When you use this method, you can't set Compress preferences because PKZIP for Windows compresses the file immediately, and uses the current settings for these preferences.

To create a new .ZIP file using drag and drop:

1.	Start PKZIP for Windows by double-clicking on the icon. The PKZIP for Windows main application window appears.

2.	Using the File Manager or Explorer, locate the file(s) you want to compress in the new .ZIP file and drag it on top of an empty section of the PKZIP main application window. (If you drop it on top of an open .ZIP file, the file will be compressed into “that” .ZIP file.) The Save as dialog box appears.

3.	Type a name for your new .ZIP file and click Save/OK.

If you are creating a regular (non self-extracting) .ZIP file, PKZIP for Windows begins to compress the files and a box appears that displays the contents of the .ZIP file.

If you are creating a self-extractor, the PKSFX for Windows - Options dialog box appears. Set options for the self-extractor, if necessary. When you click OK in that dialog box, PKZIP for Windows begins to compress the files and a box appears (the .ZIP File Display Window) that displays the contents of the .ZIP file.

To add files to an existing .ZIP file using drag and drop:

1.	Start PKZIP for Windows by double-clicking on the icon. The PKZIP for Windows main application window appears.

2.	Open the existing .ZIP archive.

3.	Using the File Manager or Explorer, locate the file(s) you want to compress in the existing .ZIP file and drag it on top of that .ZIP file window located in the PKZIP for Windows main application window.

4.	PKZIP for Windows begins to compress the files and the .ZIP file window will subsequently display the updated contents of the .ZIP file.

Note:   You cannot drag and drop files into opened encoded (e.g. *.UUE, *.XXE, *.MIM, *.MME, *.HQX) and archived (e.g. *.TAR, *.TGZ, *.GZ) files.


The PKZIP Menu Bar

Creating a .ZIP file using the PKZIP for Windows Menu bar gives you more control in compressing and extracting files. Use this method if you want to take full advantage of PKZIP for Windows’ features.

Creating a New Spanned .ZIP File

Note:   If you are creating a spanned .ZIP archive on Windows 95 or Windows NT that will be subsequently opened on a Windows 3.x PC, it is recommended that you perform a Quick Format on the diskettes before spanning .ZIP files onto them. Additionally make sure that you select a name for the .ZIP file using standard DOS 8+3 (eight characters or less with a three-character extension) naming conventions. Refer to your Microsoft Windows on-line help or User's Manual for more information on formatting diskettes or naming conventions.

PKZIP for Windows allows you to compress files onto diskettes or other media. When you create that .ZIP (or .EXE) file, you might have so many files or so many large files that, even compressed, might take up more space that is available on your diskette or other medium. With PKZIP for Windows, you can “span” a .ZIP or Windows self-extractor across multiple media.

You can only create spanned files for Windows 16-bit or 32-bit self-extractors, not for DOS self-extractors.

One of the limitations of a spanned .ZIP file is that you cannot modify it. For example, you cannot add files to a spanned .ZIP file or move files from a spanned .ZIP file to another .ZIP file.

To create a spanned file:

1.	Insert a diskette into your disk drive.

2.	Create the .ZIP or .EXE as you normally would using PKZIP for Windows.

As PKZIP for Windows compresses, when the first diskette is full, a message box that contains the following message appears:

Insert Disk #2

3.	Insert the next diskette and click OK. PKZIP for Windows continues to compress files.

4.	If PKZIP for Windows has finished compressing files, the word Done appears in the Add Status box. Click on Done to end this session.

If the current diskette is full, an Insert Disk #3 message appears. Repeat steps 2 through 4 until you get the Done message.


Converting .EXE and .ZIP Files

PKZIP for Windows allows you to convert .EXE and .ZIP files. You can convert a .EXE file to a .ZIP file, a .ZIP file to a .EXE file, and even one type of .EXE file to another (for example, a regular DOS self-extractor to a Windows 16-bit self-extractor).

Since you cannot modify a spanned .ZIP file, you cannot convert a spanned .ZIP file.

To convert files:

1.	Within PKZIP for Windows, open the .EXE or .ZIP file that you want to convert. PKZIP for Windows displays the contents of that file.

2.	From the File menu, select Convert. The Save As dialog box appears.

3.	In the Save As dialog box, do the following:

In the File name text box, type the name of the new file. If you are converting one type of .EXE to another, you must give this a new file name.

In the Save as type text box, select the type of file you want to convert the original file to.

4.	When you have finished with this dialog box, click OK. The contents of the new file appear in a window on top of the original file.


Moving and Copying Files and Archives

PKZIP for Windows allows you to copy, delete, move, and rename individual archives from within the PKZIP main application window. This functionality is available from the File menu.

Copy Archive

To copy the active archive to a specified directory:

1.	Verify that the file you wish to copy is the active file in the PKZIP main application window.

2.	Select File | Copy Archive from the menu bar. The Copy Archive dialog appears.

3.	Specify a destination directory for the archive. Use the Browse button if necessary. Click OK.

4.	A dialog verifying the copy operation will appear. Click OK.

5.	A copy of the archive now resides in the specified directory.

Delete Archive

To delete the active archive:

1.	Verify that the file you wish to delete is the active file in the PKZIP main application window.

2.	Select File | Delete Archive from the menu bar. The Confirm File Delete dialog appears.

3.	To delete the file click Yes. To cancel the delete operation click No.

Move Archive

To move the active archive to a specified directory:

1.	Verify that the file you wish to move is the active file in the PKZIP main application window.

2.	Select File | Move Archive from the menu bar. The Move Archive dialog appears.

3.	Specify a destination directory for the archive. Use the Browse button if necessary. Click OK.

4.	A dialog verifying the move operation will appear. Click OK.

5.	The archive will be moved from the source directory and should now reside in the specified directory.

Rename Archive

To rename the active archive to a specified name:

1.	Verify that the file you wish to rename is the active file in the PKZIP main application window.

2.	Select File | Rename Archive from the menu bar. The Rename Archive dialog appears.

3.	Specify a new name for the archive. It is not necessary to specify the extension. PKZIP will automatically append the appropriate file name extension. Click OK.

4.	The archive is renamed to the specified file name.

Additionally, PKZIP for Windows allows you to copy and move files between two .ZIP (or .EXE) files. Copying a file involves taking a copy of a file and putting it into another .ZIP file. After copying, both .ZIP files contain a copy of that file. Moving a file involves transferring the file from one .ZIP file to another. After you move a file, it only resides in one .ZIP file.

Since you cannot modify a spanned .ZIP file, you cannot move files from a spanned .ZIP file. You can only copy files.

Moving Files Between Two Archives

To move files:

1.	Within PKZIP for Windows, open the two .ZIP files.

2.	Click inside the .ZIP file from which you want to move files.

3.	Highlight the files within the .ZIP file that you want to move.

4.	Click the right mouse button, or select Compress from the Menu bar. A menu appears.

5.	Select Move To. The Move files dialog box appears.

If you selected files to move, the number of files you selected appears in the Files to Move area, and the Selected files radio button is selected by default. If you didn’t select files previously, the All files radio button is selected by default. The names of the .ZIP files you currently have open appear in the Opened archives box.

6.	If you are satisfied with the files you selected or all files, click on OK. If you didn’t select files, and you decide not to move “all” files, click Cancel, and repeat steps 3 through 6.

When you click OK, PKZIP for Windows begins to move the files to the other .ZIP or .EXE file.

Note:   You cannot use the Move To option to move files from or into encoded (e.g. *.UUE, *.XXE, *.MIM, *.MME, *.HQX) and archived (e.g. *.TAR, *.TGZ, *.GZ) files.

The Password area allows you to enter the password for this .ZIP file, if necessary.

5.	If the .ZIP file you are testing contains a password, you must enter that password before you can test files. Type the password in the Password box.

If the .ZIP file doesn’t contain a password, leave the Password box blank.

6.	To start testing, click on Test Integrity. PKZIP for Windows begins to test the file(s) and displays the Test Zip box.

As PKZIP for Windows tests the files, it displays the status of each file individually and of the entire test, in the Progress area of the dialog box. The name of the current file being tested appears next to the word Filename.  The percent completion changes as it tests. As each file passes the test, an OK appears next to that file. At the bottom of the dialog box, PKZIP for Windows displays the number of warnings and errors.

7.	When the last file is tested, PKZIP for Windows displays a “Done” message. When you see this message, click on the Done button to exit.


Extracting From a Windows Self-Extractor

Extracting files from a Windows self-extractor is quick and easy. With a self-extractor, you don’t have to start PKZIP for Windows to extract files.

This section contains instructions on extracting from “outside” PKZIP for Windows. From within PKZIP for Windows, extracting from a self-extractor works the same as a regular .ZIP file.

To extract from a Windows self-extractor:

1.	Locate the file using the Windows File Manager (for Windows 3.1x and Windows NT 3.51) or with My Computer or Explorer (for Windows 95 and Windows NT 4.0). This file should have a .EXE extension.

2.	Double-click your left mouse button on the self-extractor. The PKSFX extract dialog box appears.

Some of the items in this dialog box default from the PKZIP for Windows - Options dialog box, which is the one used to set options when the self-extractor was created. Items that are disabled cannot be edited.

3.	Complete the appropriate items. Set options, as necessary. A description of each “button” in this dialog box follows.

About button

Click on this button to get general information on PKZIP for Windows licensing and disclaimers.

Information button

Click on this button to read additional information included with this self-extractor. If the creator of the self-extractor did not include a comment, this button will be disabled.

Test button

Click on this button to perform a “test” extraction.

Extract button

Click on this button to extract the files from the self-extractor onto your computer.

Cancel button

Click on this button to cancel the extraction.

4.	When you have finished with this dialog box, click on Extract. PKZIP for Windows begins to extract the files.


Extracting From a DOS Self Extractor

To extract files from a DOS self-extracting .ZIP file (a .ZIP file with a .EXE extension), you do not have to use PKZIP for Windows. You can extract directly from your Windows File Manager, or from a DOS prompt. In both cases, PKZIP for Windows opens a DOS window when it begins to extract.

Extracting Using the Windows Explorer or File Manager

To extract files using the Windows Explorer or File Manager:

1.	Locate the file using the Windows Explorer or File Manager. The file should have a .EXE extension.

2.	Double-click on the .EXE file. A DOS window opens and the files within the self-extracting file are extracted into the directory where the self extractor (.EXE) resides.

Extracting Directly From a DOS Prompt

To extract files from a self-extracting .ZIP file “without” using the File Manager, you may simply open a DOS window and type the name of the self-extracting file. This method works like PKZIP for DOS . You may specify locations, special options, and also extract individual files.

When you extract from a self-extracting file, all you have to do is type the name of the .EXE file. This file contains the necessary commands and programs you need to extract the file.

In general, to extract files:

1.	Open a DOS window by clicking on the MS-DOS icon.

2.	Change to the directory where the self-extracting (.EXE) file resides.

You can type the location as part of the command in step 3.

3.	At the DOS prompt (for example, C:\), type the name of the .EXE file you are extracting from and press ENTER. For example, if the name of the file is apples.exe, you would type apples. (You do not have to type the .EXE.)

To add flexibility to your self-extraction, you can also specify:

•	A location for the file(s) being extracted.

•	Individual files to extract.

•	Options that add flexibility to your extraction.

Specifying a Location

PKZIP for Windows extracts the files into the directory you are in, unless you change that location. To change locations, you can type the drive and/or path. For example, if you were extracting from a file called “apples.exe” and you wanted to extract it to the D drive in the fruit\temp directory, you would type   the following:

apples.exe    d:\fruit\temp

Selecting Individual Files to Extract

When you extract files, you do not have to extract all of the files from the .EXE file. You can extract as many as you want. For example, if you wanted to extract two files from the apples.exe file, and the names of those files are sour.doc and sweet.doc, you would type the following:

apples.exe   sour.doc   sweet.doc

You can also use DOS wildcards to specify a file pattern. For example, if you wanted to extract all files that end in .DOC, you would type something similar to the following:

apples.exe  *.DOC

This feature is not available for PKSFX-Jr.

Specifying Options

With self-extracting files, PKZIP for Windows provides several options that help customize your data extraction. When you use an option, it must appear as the first element after the name of the .EXE file in your command. For example, the -d option allows you to re-create directories in the location in which you are extracting the files. To do this, you would type something similar to the following:

apples.exe  -d   *.DOC

You can use more than one option in the same command. Type the options right next to each other, “except” when using the -s option.

The following is a description of each option. The -o and -h  options are the only options that apply to PKSFX-Jr.

This option:	Allows you to:
-c	Extract to the console.
-d	Re-create directories that are stored in the .EXE file.
-l	Display the software license agreement on your screen.
-n	Extract only files that are newer than the corresponding files in your destination (extract) directory.
-o	Overwrite existing files of the same name in your destination (extract) directory.
-p [a] [b] [c] [#]	Extract to a printer. a=Extract in ASCII Mode (e.g. -pa1) b=Extract in BINARY Mode (e.g. -pb2) c=Extract to specified COM port (e.g. -pac1)
-s [password]	Decrypt with a password.
-t	Test the integrity of the .ZIP file.
-h or \?	Get online help on using these options.


Extracting From a Spanned .ZIP or .EXE File
Extracting From a Spanned .ZIP File

To extract files from a spanned .ZIP file:

1.	Insert the “last” diskette in your series of your spanned .ZIP file. For example, if the .ZIP file spans three diskettes, insert the third diskette.

2.	Using PKZIP for Windows, open the .ZIP file from which you want to extract.

3.	Select the Extract option from the Extract menu, or click on the “extract” Toolbar button. The Extract dialog box appears.

4.	Proceed with selecting the files to extract, setting preferences, and so on.

5.	When you are finished, click OK in the Extract dialog box. PKZIP for Windows displays the following message:

Insert Disk #1

6.	Insert the first diskette in the series and click OK. PKZIP for Windows begins to extract from that diskette. When it finishes, the following message appears:

Insert Disk #2

7.	Insert the next diskette and click OK. Repeat these steps for any additional diskettes.

When the PKZIP for Windows extracts from the final diskette, the Done message appears.


Extracting From a Spanned .EXE (self-extractor) File

These instructions show you how to extract “all” files from a spanned self-extractor without starting PKZIP for Windows. To extract individual files from a spanned file, you have to start PKZIP for Windows first, then open the appropriate .EXE file.

To extract all files from a spanned Windows self-extractor:

1.	Insert the first diskette in the series of your spanned self-extractor.

2.	Double-click your left mouse button on the self-extractor icon. The following message appears:

Insert last disk

3.	Insert the “last” diskette in the series of your spanned self-extractor. For example, if the self-extractor spans three diskettes, insert the third diskette.

4.	When you have inserted the last diskette, the PKSFX dialog box appears.

Some of the items in this dialog box default from the PKZIP for Windows - Options dialog box, which is the one used to set options when the self-extractor is created. Items that are disabled (e.g., Recreate subdirectories) cannot be edited.

5.	Complete the necessary items. A description of each “button” in this dialog box follows.

About button

Click on this button to get general information on PKZIP for Windows licensing and disclaimers.

Information button

Click on this button to read additional information included with this self-extractor. If a comment was not included, this button will be disabled.

7.	Insert the first diskette in the series, and click OK. PKZIP for Windows begins to extract from the self-extractor.

The status of extracting files appears at the bottom of the PKSFX dialog box.

When PKZIP for Windows is finished with this diskette, the following message appears:

Insert Disk #2

8.	Insert the next diskette and click OK. Repeat these steps for any additional diskettes.

When PKZIP for Windows extracts from the final diskette, the Extract dialog box will disappear.


Opening a File Within a .ZIP File

You can open a file that appears within a .ZIP file. For example, if your .ZIP file contains a  README.TXT file, you can open that file while you are in the .ZIP file.

To open a file within a .ZIP file:

1.	Open your .ZIP file.

2.	Click your left mouse button “once” on the file within the .ZIP file that you want to open. That file is highlighted.

3.	Do one of the following:

From the Extract menu, select Open. The file you selected opens in the associated application.

Double-click your left mouse button on the file within the .ZIP file. The file you selected opens in the associated application.

If PKZIP for Windows does not recognize the file you are trying to open, the following message appears:

No File Association For This Type

Add the appropriate file extension to your Windows registry (Windows95) or WIN.INI file (Windows 3.1 or greater).


Extracting Files Using the PKZIP Wizard

The PKZIP for Windows Wizard systematically guides the novice user through the steps necessary to extract files contained in a .ZIP archive. To access the Extraction Wizard:

1.	Run PKZIP for Windows. The PKZIP for Windows main application screen appears.

2.	From the Menu bar, select File | Wizard or click the [image] item on the tool bar. A dialog labeled PKZIP for Windows Wizard - Welcome will appear.

3.	Click the radio button next to the Extract all files stored in an existing .ZIP file option.

4.	Click the Next button. The wizard will proceed to the next dialog.

5.	Follow the instructions on the various wizard dialogs.


Viewing Files Within a .ZIP File

When you open a .ZIP file, you might want to view the contents of one of the compressed files. PKZIP for Windows allows you to open individual application files right from the .ZIP File Display Window.

To view the contents of an application file:

1.	Open the desired .ZIP file.

2.	Specify a temporary directory for PKZIP for Windows to extract the file. To do this, select Extract from the Menu Bar, Preferences from the Extract menu, and enter the directory in the Temporary Extract Directory box.

3.	Select the file you want to view by double-clicking on the file. PKZIP for Windows automatically extracts the file into the temporary directory, and the file opens.

The file you open needs to have a Windows file association for that type of file.  For example, to view the WIN.HLP file, which has a windows file association of Winhelp for .HLP files, double clicking will cause winhelp to run the WIN.HLP file.

If there is no file association for that file type, an error message appears. Please refer to your Windows documentation for further information about file associations.


PKZIP Viewing Options

PKZIP for Windows contains several different options to view a .ZIP file. These options appear on the View menu.

The GridLines option allows you to turn on and off the gridlines that border the list of files.

The Zoom In option allows you to zoom “in” to the .ZIP file contents.

The Zoom Out option allows you to zoom “out” of the .ZIP file contents.

The Font option allows you to change the font name, style, and size of the text within the .ZIP File Display Window.


Sorting Files Within a .ZIP File

PKZIP for Windows allows you to sort the files within a .ZIP file on your screen several different ways, making it easier to find the files that you want.

To sort files, use the Sort option on the Menu bar.

Sort by Filename in ascending or descending order. Ascending is normal alphabetical order. Descending is reverse alphabetical order.

Sort by Extension in ascending or descending order. Ascending is normal alphabetical order. Descending is reverse alphabetical order.

Sort by File Size in ascending or descending order. Ascending is from smallest to largest. Descending is from largest to smallest.

Sort by Date in ascending or descending order. Ascending is from oldest to newest. Descending is from newest to oldest.

Sort by Compression Ratio in ascending or descending order. Ascending is from smallest to largest. Descending is from largest to smallest.

Sort by CRC 32 value in ascending or descending order. Ascending is from smallest to largest. Descending is from largest to smallest.

Unsorted does not sort the files. They appear in the order that they were compressed.


Cascade and Tile .ZIP Files

You might find it necessary to open multiple .ZIP files at the same time. PKZIP for Windows makes it easier to view these files by providing two ways to arrange the .ZIP File Display Windows that contain them.

To arrange windows, use the Windows option on the Menu bar.

Cascade - This option allows you to place the .ZIP File Display Windows on top of each other, with only the top part of each window showing. Each window is slightly lower and to the right of the one below it. You can still access all files, you just can't see the entire contents of the each .ZIP file.

Tile -  This options allows you to give equal space to every window you have opened. You can see the partial contents of each window,  but each one is relatively small.


Compress Preferences

When you create a new .ZIP file or add files to a .ZIP file, you can change various .ZIP parameters. This provides greater flexibility for compressing files.

When you select Preferences from the Compress menu, or click on the Preferences button in the Add Files dialog box, PKZIP for Windows displays the Compress Preferences dialog box.

To set the changes as the new defaults, click on Save as default “instead” of OK. This sets defaults for “all” changes made in this box. To specify which directory will appear by default in the Add files dialog, the Open dialog, as well as the PKZIP temporary directory, click the Directories button. The Directories dialog will appear.

Compression

This area allows you to change the compression method. Click on the radio button that appears next to the method you want to use.

Super fast - Use this method if want the fastest - but least - compression. If speed is a priority, this method is for you.

Fast - Use this method if you want the second fastest compression and the second least compression. This method is slower than Super fast but provides more compression.

Normal - Use this method if you want the best balance of speed and compression. This is the default method.

Extra - Use this method for the most - but slowest - compression. If compression is a priority, this method is for you.

Store - Use this method if you want no compression, or if you know that a file will not compress.

Attributes

This area allows you to include files in your .ZIP file that contain specific attributes. You can select as many file attribute types as you want.

Read-Only -  Compress read-only files.

Hidden - Compress hidden files. (Hidden files cannot be displayed in Add Files or using the DOS dir command. They are displayed within a .ZIP file.)

System - Compress system files. These files are used by the operating system.

Retain attributes - Retain the attributes in the .ZIP file so you can extract the files with the attributes.

.ZIP File Date

This area allows you to set the date of a .ZIP file. Click on the radio button that appears next to the date you want to use.

Today's date - Apply today's date to the .ZIP file.

Newest date - Apply the date of the newest file within the .ZIP file to the .ZIP file.

Oldest date - Apply the date of the oldest file within the .ZIP file to the .ZIP file.

Retain .ZIP date - Keep the current date of the .ZIP file.

Path Information

This area allows you to store directory path information in your .ZIP file. For example, if you compressed a file from the \doc\resume directory, you can include the “\doc\resume” in your .ZIP file.

No path information - Do not include path information with each file in the .ZIP file; only include the filename.

Relative path - Include relative path information with each file in the .ZIP file.

Full path - Include the entire path with each file in the .ZIP file.

Use MS-DOS name - Store the 8-character name, 3-character extension for files compatible with this MS-DOS naming convention.

Archive Bit

ZIP if archive bit is set - Compress files that have had their archive bit set, which means the file has changed since the last backup.

Clear archive bit - Clear the archive bit after the file is compressed.

Miscellaneous

This area contains more options that add flexibility to your data compression.

Store Volume Label -  Store the volume label from the desired drive within the .ZIP file.

Include Subdirectories (Recurse) - Compress files that appear in subdirectories of the current directory. If you use this option, you don't have to select the files within each subdirectory. If you selected specific files to be compressed, PKZIP for Windows will include only files within the subdirectories that match that criteria.

Set 204g file limit - Ensures PKZIP for DOS 2.04g  compatibility for .ZIP files created with PKZIP for Windows by setting the limit on the number of files that can be added to a .ZIP archive from 65,535 to 16,383.


Extract Preferences

When you extract a file from a .ZIP file, PKZIP for Windows allows you to change various .ZIP parameters. This provides greater flexibility for extracting files.

When you select Preferences from the Extract menu, or click on the Preferences button in the Extract Files dialog box, PKZIP for Windows displays the Extract Preferences dialog box.

To set the changes you make in this dialog as the new defaults, click on Save As Default instead of OK. This sets defaults for “all” changes made in this box.

Extract Options

This area allows you to control how PKZIP for Windows handles files being extracted that have the same name as files in the target directory (the directory you are extracting to).

Overwrite - Overwrite files in the target directory without prompting you.

Update - Extract files that contain a file with the same name and date in the target directory “and” that are newer than the files in the target directory.

Associating the .ZIP Extension with PKZIP

By default, the PKZIP install program registers the PKZIP for Windows program with the .ZIP filename extension. This allows you to open .ZIP files from Windows Explorer or File Manager without opening PKZIP first. PKZIP automatically starts when you double-click on the filename in Explorer or File Manager. This .ZIP extension association can be disabled on install or potentially changed by other install programs. As such, PKZIP allows you to manually set the .ZIP extension association to PKZIP for Windows. To manually associate PKZIP for Windows (pkzipw.exe) with the .ZIP filename extension, complete the following steps:

1.	Run PKZIP for Windows. If the .ZIP filename extension is not presently associated with the version of PKZIP you are running, the Set association dialog will appear. Proceed to step 4. If the Set association dialog is disabled or the .ZIP filename extension is already associated with PKZIP, this dialog will not appear on startup. If you are unsure as to whether the .ZIP filename extension is registered to PKZIP for Windows, you may proceed to step 2.

2.	Click File | Associate to .ZIP on the menu bar. If the file association is already set up properly, the Associate to .ZIP item will be grayed out. If the file association is not presently set up, you may select this item from the File menu. The Set Association dialog will appear:

3.	If you wish to continue by associating the .ZIP extension with PKZIP for Windows click the Yes button. To exit without changing the association, click the No button.

Please confirm before you click the No button whether you wish to be prompted with this dialog each time you run PKZIP for Windows. If you do not wish to be prompted, check the Do not ask me this question on startup checkbox.


Uninstalling PKZIP for Windows

To uninstall PKZIP for Windows:

1.	Locate the PKWARE Program Group. If you are unable to find a Program Group for PKWARE, use Windows File Manager or Explorer to locate the installation directory. (\pkware\pkzipw by default).

2.	Run the PKZIP for Windows Uninstall program (pkuninst.exe) by double clicking the appropriate icon.

3.	A dialog labled Uninstall PKZIP for Windows will appear displaying the specific components  that will be uninstalled. Verify that you wish to uninstall the listed components.

4.	To abort, click the Cancel button. If you wish to continue with the uninstall click OK. PKZIP for Windows will be removed from your system.

What is a Self-Extracting File?

A self-extracting file is a type of ZIP file that you can extract from without actually using PKZIP for Windows. In fact, you don’t even need PKZIP for Windows installed on your computer. This self-extracting file contains “unzipping” instructions directly in the .EXE file. All self-extracting files end in .EXE.

With PKZIP for Windows, you may create the following types of .EXE files:

PKSFX DOSFULL	DOS based self-extractor. (Included in the Shareware, Registered, and Distribution Licensed versions of PKZIP).
PKSFX JRDOS	A smaller, more compact version of the DOS self-extractor. This file contains less extraction options than the regular DOS self-extractor, and requires less memory to run. (Included in the Shareware, Registered, and Distribution Licensed versions of PKZIP).
PKSFX WIN16	16-bit "Windows" self-extractor that works with versions of Windows starting with 3.1 and later. This includes long file name support under Windows95. (Included in the Shareware, Registered, and Distribution Licensed versions of PKZIP).
PKSFX WIN32...	32-bit "Windows" self-extractor that works with versions of Windows95 and NT (Intel, DEC Alpha, Power PC). This includes long file name support under Windows95 and Windows NT. (Available in the Registered and Distribution Licensed versions of PKZIP).
PKSFX OS/2...	OS/2 self-extractor that works with the OS/2 Operating System. (e.g. OS/2 Warp version 4). This self-extractor is included in the PKSFXS.DAT file described here. (Available in the Distribution Licensed version of PKZIP).
PKSFX SOL2X...	UNIX self-extractors that work with several different flavors of UNIX. (e.g. Sun Solaris 2.x SPARC). These self-extractors are included in the PKSFXS.DAT file described here. (Available in the Distribution Licensed version of PKZIP).

You select the type of .EXE file when you create the file.

Creating Self-Extractors With the pksfxs.dat File

The Distribution Licensed version of PKZIP includes an external data file called pksfxs.dat. It is only available and will only function with the Distribution Licensed version of PKZIP. The pksfxs.dat file allows users to create self-extractors (in addition to the extractors included with the Shareware and Registered versions of PKZIP) for several different platforms. The Save As dialog will list the available self-extractors, including those contained in the pksfxs.dat file.

If you plan to place the pksfxs.dat file in a directory other than the installation directory, you must set an environment variable (SET PKSFXDATA=<path to the pksfxs.dat file>) for the file. On Windows 3.1x/95/NT 3.51 systems, this variable is set in the autoexec.bat file. On Windows NT 4.0 systems, this variable is set through the control panel.

To create a self-extracting file from the pksfxs.dat file:

1.	Double-click your mouse on the PKZIPW icon. The PKZIP for Windows main application screen appears.

2.	From the Menu bar, select File. The File menu appears.

3.	Select New. The Save As dialog box appears.

•	Specify a destination directory for your self-extracting file, if different than the current directory.

•	In the Save as type field, select the type of self-extractor you wish to create. If, for example, you wish to create an OS/2 based self-extractor select the following:

PKSFX OS2_X86_C260 File (*.EXE)

5.	To save your changes, click Save/OK. The Add Files dialog box appears.

6.	Select files to add to your .EXE file. When you have finished adding files, click OK in the Add Files dialog box.

7.	Sice you selected a Windows based self-extractor in step 4, the PKSFX for Windows - Options dialog appears. Specify appropriate options  for your self-extracting file, if necessary.

8.	When you have finished specifying options, click OK in the PKSFX for Windows - Options dialog box.

PKZIP for Windows begins to compress the selected files into your self-extracting file. The first line displays the percentage completed for the entire .EXE file.  The second line displays the percent completed for the current file that is being compressed.  The lower area shows how each file was compressed and the overall percentage that it was compressed.

9.	After all the files are compressed, click OK button to remove the Add Status dialog box.  PKZIP for Windows displays the contents of the file.

Note: PKWARE will periodically update the pksfxs.dat file as self-extractors are developed for other operating systems and platforms. As updates are created, they will be made available to Distribution Licensed users of PKZIP who have purchased the subscription option. Contact PKWARE for further information.


Setting PKSFX Options

The following is a description of each item of the PKZIP for Windows - Options dialog. Please note that some of these options are only available in the Registered and/or Distribution Licensed versions of PKZIP for Windows.

Title bar name

When files are extracted from a Windows self-extractor, a PKSFX extraction dialog appears that allows the user to specify additional extraction options. If you wish to specify a text string in the title bar of the PKSFX extraction dialog, type it in this box. The title bar is the top portion that identifies a particular dialog box. This feature is only available in the Distribution Licensed version of PKZIP for Windows.

Extract To

Type the destination directory for the files archived in the self-extractor. If you do not specify a drive letter (e.g. "C"), PKZIP will use the drive on which your temporary directory is located. If the directory (or directory path) you specify does not exist, PKZIP will ask you if you wish to create it.

The path specified in the Extract To box will appear in the corresponding Extract To box when the self-extractor is run. This dialog appears when you double-click on the self-extractor icon to begin extraction.

Run after extraction

If you wish to automatically run an executable file after files are extracted from a self-extractor, specify a full path to that executable file here. If you are unsure of the location of the file, use the Browse button. This feature is only available in the Distribution Licensed version of PKZIP for Windows.

Recreate subdirectories

If you wish to recreate subdirectories stored with the files archived in the self-extractor on extraction, click this check box.

Note: When you compress files into a standard or self-extracting .ZIP archive, PKZIP allows you to store directory path information in addition to the files. You then have either the option of extracting the files alone or with their corresponding paths.

Display Messages

When you extract files from a self-extractor, PKZIP may display warning messages in the display area located at the bottom of the Extract dialog. Depending on your computer, these messages might flash on and off your screen before you can read them. If you wish to display each warning message in a separate message box, click this check box.

Note: The Display Messages check box applies only to warning messages. It does not apply to error messages.

Overwrite

This area allows you to specify how overwrite operations should be handled by PKZIP. A lisitng of the available overwrite options follows:

Prompt - Prompt you every time PKZIP encounters a file name in the destination/extraction directory that matches the name of the file being extracted.

Always - Always overwrite those files that exist in the destination/extraction directory regardless of  matching file names (PKZIP will not prompt you).

Never - Never overwrite those files that exist in the destination/extraction directory regardless of  matching file names (PKZIP will not prompt you)

Create program group

PKZIP allows you to create a program group for files stored in your self-extracting .ZIP archive. You also have the option of creating icons for the those files. This feature is only available in the Registered and Distribution Licensed versions of PKZIP for Windows.

What is a program group?

Creating a program group involves actual group creation followed by the creation of the individual items that will displayed in the group. Each item represents a program or application that you want grouped with other programs and applications.

The Create program group area contains two components:

•	The check box, which enables you to “create” program groups.

If you check this box, the corresponding box in the PKSFX dialog box (the box that appears first when the files from this self-extractor are extracted) will also be checked.

•	The Edit button, which enables you to “enter” program groups.

To create a program group:

1.	Click the Edit button that appears to the right of Create
program group. The Create Program Group dialog box appears.

2.	In the Group Name item, type a name for your program group. This name will appear as the title for the program group.

3.	To add group items, click on Add. The Group Item dialog box appears.

4.	Make the appropriate entries for the following items:

Caption

Type a caption for this group item. This will appear directly below the icon for this item. If you do not type a caption name, Windows uses the name of the program from the Command line text box.

Command line

Select the name of the program to be associated with this group item. Use the Browse button to locate that program.

When you click on a file using Browse, the full path of that file appears in the box. You should probably change all full paths to relative paths because the user (the person extracting from this self-extractor) can change the Extract To box in the PKSFX dialog box. All relative paths are relative to the path in the Extract To box of the PKZIP for Windows - Options dialog box.

Icon

To select an icon for your self-extractor:

•	In the first box, type the location and name of the file that contains the icon.

•	In the second (smaller) box, type the number that corresponds with the existing icon you want to use. The first icon in the file is 0 (zero), the second is 1, and so on.

Why register file extensions?

PKZIP for Windows allows you to register extensions for selected files contained in a self-extracting .ZIP archive. If, for example, a file exists in your self-extracting .ZIP archive with a .htm extension, you have the option of selecting the application with which you wish to associate files with the .htm extension. The selected application would then open by default when the .htm file is executed via File Manager or Explorer.  Keep in mind that once PKZIP completes such an operation, all files with a particular extension will be associated with a particular application. This feature is only available in the Registered and Distribution Licensed versions of PKZIP for Windows.

What is a Program Group?

A program group is a collection of one or more programs associated with a software application. For example, if you are distributing multiple programs with your self-extractor, you can group each program (referred to in PKZIP for Windows as a “group item”) into one program group. You can even have your self-extractor create “icons” for each group item.


Why Register File Extensions?

If you are distributing a program with your self-extractor that contains a file extension that the user of the self-extractor might not have registered on their system, you can have your self-extractor register it for them. So when the user extracts from your self-extractor, he or she can choose whether or not to automatically register extensions.

Adding Files With a List File

Rather than manually adding individual files to a .ZIP archive, you have the option of using a List file in PKZIP for Windows. A List file is an ASCII text file that contains file names and their locations. A List file can be an ideal solution for users who archive specific file sets on a regular basis. It saves time in that it is not necessary to specify appropriate file names and paths each time you wish to compress these files with PKZIP for Windows. A List file may contain wild card specifications (*,?) as well as exact file names and paths.

A List file might look similar to the following:

c:\*.exe

z:\*.doc

\tut\*.doc

\tut\?????.*

pkware.txt

When you do not specify a disk drive (e.g. c:) in a list file item, PKZIP will assume that you wish to add the current working drive into your Files & Directories To Zip designation. Similarly, if you do not specify a directory path in a list file item, PKZIP will assume that you wish to add the current working directory into your Files & Directories To Zip designation. As you can see, the format follows standard DOS/Windows path and wildcard conventions. You may create and/or modify your List file with any standard ASCII text editor. (e.g. Notepad) Save the file with an easy to remember filename (e.g. listfile.txt), in a directory where you can locate it easily later.

To use a List file:

1.	Start PKZIP for Windows by double clicking on the icon. The PKZIP for Windows main application screen appears.

2.	Open an existing .ZIP archive and select Compress | Add Files from the menu bar or create a new .ZIP archive by selecting File | New from the menu bar. Specify a name and location for your new .ZIP archive. The Add Files dialog box appears.

3.	Locate the List file you created and highlight it by clicking on it once.

4.	Click the Add List File button. The contents of your List file will appear in the Files & Directories to Zip box.

5.	When you are finished click OK. Any files that you specified in the Add Files dialog, including those in you List file are added to the .ZIP archive.


File Format Support

PKZIP for Windows allows you to extract files from encoded or Tar & GZIP archived data. PKZIP will decode and extract files created with the following encoding and archive schemes:

Encoded File Type	Common File Extensions
UUEncode	*.UUE
XXEncode	*.XXE
BinHex	*.HQX
MIME	*.MIM *.MME
Tar	*.TAR
GZIP	*.GZ *.TGZ
Extracting Files From an Encoded File

To open and extract files from an encoded file:

1.	Start PKZIP for Windows by double clicking on the icon. The PKZIP for Windows main application window appears.

2.	From the Menu bar, select File | Open. The Open dialog box appears.

3.	In the Files of type box, select the file type you wish to open. For example, Encoded Files (*.UUE; *.XXE; *.MIM; *.MME; *.HQX) or Tar & Gzip (*.TAR; *.TGZ; *.GZ). Those files that match the selected file pattern(s) will appear in the Open dialog box.

4.	Double-click the file that you wish to open or simply type the path and/or name of the file in the File name box and click the Open button. PKZIP for Windows displays the contents of the file in the main application window.

5.	Select the files you wish to extract.

6.	From the Menu bar, select Extract | Extract files. The Extract dialog appears

7.	Select a destination for the files to be extracted. Type a location - such as a drive or directory path - or use the Browse button to search for a location.

8.	Set Preferences, if needed, by clicking on the Preferences button and clicking on the appropriate radio buttons and checkboxes.

9.	When you have finished selecting a destination, click on Extract to start extracting.  PKZIP for Windows displays the Extract box.

10.	As PKZIP for Windows extracts the files, it displays the current status of the  extraction process in the Progress area of the dialog box. The name of the current file being extracted appears next to the word Filename.  The percent completion changes as it extracts. As each file is extracted, an OK appears next to that file. At the bottom of the dialog box, PKZIP for Windows displays the number of warnings.

11.	When the last file is extracted, PKZIP for Windows displays a “Done” message. When you see this message, click on the Done button to exit.

Converting .ZIP Files to UUEncoded Format

PKZIP for Windows allows you to convert .ZIP files (standard and self-extracting) to the UUEncoded format. This converts .ZIP files from binary format to ASCII format allowing you to send such files safely via email.

To convert files to UUEncoded format:

1.	Open or create the .ZIP file that you wish to UUEncode. The file will be displayed in the PKZIP for Windows main application window.

2.	From the menu bar select File | UUEncode .ZIP file.

3.	PKZIP will UUEncode the file and place it in the same directory as the source (original) .ZIP file. It will have the same name as the source .ZIP file however PKZIP will replace the .ZIP or .EXE extension with a .UUE extension. (e.g. filename.zip --> filename.uue)
