- PKAZip, the Amiga ZIP tool!
- ---------------------------
-
- PKAZip is the PKWare ZIP tool for the Amiga. PKWare's MS-DOS
- product line includes:
-
- PKZIP - The FAST data compressor!
- PKUNZIP - The FAST data decompressor!
- PKZFIND - A tool to locate files in directories or ZIP files!
- STUPENDOS - A directory utility which provides access to MS-DOS
- files as well as ZIP files!
-
- PKAZip is all of these tools and more! It provides the Amiga user
- with a fully-Intuitionized tool written specifically for the Amiga.
- PKAZip provides COMPLETE support for the Amiga's file system while
- retaining compatibility with PKWare's PKZIP and PKUNZIP tools.
- PKAZip provides functions to create, examine, extract, test, modify,
- display and print files which are in the ZIP compressed format.
- PKAZip provides additional functions which support ZIP creation and
- extraction. It provides full support for recursive copy and delete
- to allow you to copy or delete any or all files in one or more
- directories and subdirectories. PKAZip will create directories as
- needed to support the copy operation and ZIP file creation.
-
- PKAZip makes compressed file catalogs easier to use by allowing
- file comments to be added to each file in the ZIP catalog. Comments
- may be added or modified anytime, without the need to extract files
- from the ZIP file. PKAZip offers more convenience by providing you
- with a tool to change file protection bits and rename files while
- they are still in the compressed state. In addition, PKAZip allows
- you to attach a 255 character ZIP comment to the ZIP file to help
- identify the ZIP file in the future.
-
- PKAZip offers an inovative and powerful search feature that can
- locate those hard to find files! Search allows you to locate files
- by name or by file comment in any directory and most importantly,
- INSIDE compressed ZIP files! Now you have the power and convenience
- you need to quickly find those files.
-
- Above all, PKAZip does all of this much faster than competitive data
- compression/extraction tools while increasing data reliability with
- the use of 32-bit Cyclic Redundancy Check (CRC). The full-Intuition
- interface provides easy to use buttons and menus to get you started
- quickly! Even the experienced ZIP user will find it easy to create
- and maintain large collections of ZIP files on the Amiga.
-
-
- How to get started
- ------------------
-
- To use PKAZip from the Command Line Interface, copy PKAZip to a
- directory which is in your path. Set the Amiga's stack to at least
- 40000 bytes. From the command line prompt, type PKAZip followed by
- the Return key to launch the program.
-
- To use PKAZip from the WorkBench, place the PKZIP program and icon
- in any WorkBench drawer by dragging it into that drawer. Double
- click on the PKAZip icon to launch PKAZip.
-
- Once PKAZip is started, you will get a message that PKAZip can not
- find ZIP.PREFS and ZIP.LICENSE. This is normal at this point. Click
- on the OK box in these messages. After a slight delay, PKAZip is ready
- for use. Use PKAZip to copy ZIP.HELP, ZIP.LICENSE and ZIP.PREFS to the
- S: directory:
-
- - Enter the drive and directory where these files exist into the
- source string box in the lower left corner of PKAZip's screen.
-
- - Enter S: into the destination string box in the lower right
- corner of the screen.
-
- - Select ZIP.HELP, ZIP.LICENSE and ZIP.PREFS by clicking on each
- filename in the central files box.
-
- - Click the COPY button which is below the central files box. This
- should copy the files into the S: directory.
-
- At this point, you can exit PKAZip and restart the program to insure
- that PKAZip is able to find the files you just copied into the S:
- directory.
-
- Under normal use, after you start PKAZip, you can either click in the
- main files window (the box in the center of the screen), type in a
- drive and directory name in the left directory box or use the DEVICE
- button to select any physical or logical drive in your system.
-
- Please examine the license and help files by using the LICENSE and HELP
- buttons on PKAZip's main screen. These files contain additional and
- useful information about PKAZip. You must have zip.license in the S:
- directory to operate PKAZip.
-
-
- Important Note
- --------------
- If you have only 512K of memory, you must assign PKTEMP: to one of
- your disk drives. This forces PKAZip to create temporary ZIP files
- on the disk drive and not in memory. If you have 1 Meg or more of
- memory, you can assign PKTEMP: to RAM: and get a significant increase
- in performance during ZIP creation or modification.
-
- If you do not assign PKTEMP:, PKAZip will use T: as its temporary
- storage location.
-
-
- Zipping Files
- -------------
- Creating ZIP files is very easy with PKAZip! As an example of how easy
- it is to create a ZIP file for distribution over a BBS, assume there
- are five files you need to compress. Also, you want to save the files
- and their pathnames so the person that receives your ZIP file will be
- able to extract the files to the proper directories. The file you wish
- to create will be named DIST.ZIP and you want to create the ZIP file
- on your RAM disk to speed things up. Finally, you want to add a ZIP
- comment to the ZIP file so everyone will know you created it.
-
- Here is the list of files you want to compress:
-
- dh0:s/script_file.txt
- dh0:c/my_command
- dh0:c/second_command
- dh0:l/my_handler
- dh0:libs/my_library
-
-
- Create the ZIP file by following these steps:
-
- - Select LONG PATH NAMES from the COMPRESS menu to force PKAZip
- to store each filename with its complete path.
-
- - Type RAM:DIST.ZIP into the destination string box in the lower
- right corner of PKAZip's screen and press the Return key.
-
- - Type dh0:s into the source string box in the lower left corner of
- PKAZip's screen and press the Return key. This should display
- the list of files in the dh0:s directory.
-
- - Scroll the file list until script_file.txt is visible and click
- once on the line containing script_file.txt to select this file.
-
- - Press the COMPRESS button below the files list to activate the
- compression process. PKAZip will automatically decide if the
- compression technique should be imploding (best compression -
- most time), shinking (good compression - very fast) or storing
- (no compression). You can override PKAZip by using the FORCE
- SHRINKING option from the COMPRESS menu.
-
- PKAZip should create the ZIP file on the RAM: drive and add
- a file with s/script_file.txt as the filename.
-
- - Change the source string box in the lower left corner to dh0:c.
-
- - Select both my_command and second_command using the mouse.
-
- - Press the ZIP button below the files list to add these two
- files to the DIST.ZIP file on the RAM: drive. These files will
- be added as c/my_command and c/second_command respectively.
-
- - Change the source string box to dh0:l and dh0:libs to add
- the renaming two files to the ZIP file.
-
- - Change the source string box to RAM: to display the list of
- files on RAM: which should include DIST.ZIP. Select DIST.ZIP
- and press the INFO button below the files list. This should
- display the File Info Window which contains a string box which
- allows you to enter the name of your BBS. This string box will
- allow you to enter a 255 character ZIP comment.
-
- Once you have entered your comment, press the SAVE button in
- the File Info window to save your comment with the ZIP file.
-
- - You are finished! The ZIP file is ready to be uploaded to a
- BBS.
-
- Extracting Files
- ----------------
-
- Assume you just downloaded the DIST.ZIP file from your local bulletin
- board. Also assume you downloaded it to your RAM: drive. You can
- examine the ZIP file to determine if it has a ZIP comment attached to
- it by running PKAZip and entering RAM: into the source string box.
-
- Select the file and press the INFO button below the files list. This
- will display the File Info window which contains the ZIP comment if any.
- Press the CANCEL or ABORT buttons to exit the File Info window and
- return to the files list.
-
- You can view the contents of the ZIP file by simply changing PKAZip's
- source string box to RAM: and double clicking on the DIST.ZIP filename.
- This will display a sorted list of files contained in the ZIP file.
- You can alternate between viewing this list with size information, date
- and filename or file comment and filename by repeatedly pressing the
- COMMENT button below the files list.
-
- You can display any files in the ZIP file by selecting them and pressing
- the DISPLAY button. This allows you to read the information that is
- usually posted with ZIP files to help you use the programs.
-
- As an example, assume you have examined the ZIP file and you want to
- extract the files to your harddrive named dh0:.
-
- - Type dh0: into the destination string box and press the Return
- key. This tells PKAZip where to put the files during extraction.
-
- - Assuming you are still looking at the list of files contained
- in the ZIP file, you may simply select those files you wish to
- extract.
-
- - Check the Extract Menu to make sure USE PATHNAMES is checked.
- This will insure that PKAZip will use any path information stored
- with the filename. PKAZip will prompt you if it needs to create
- any directories during the extraction process.
-
- - Press the UNZIP button to begin the extraction process. Any
- selected file will be extracted to the destination drive and
- placed in the correct directory for you!
-
-
