- PKPress 2.0, Copyright 1993, Maritime Computer Services
-
- First - PKPRESS.EXE must be in your path, and PKZIP and PKUNZIP
- ABSOLUTELY MUST BE IN YOUR PATH!!! Also, FIND.EXE,
- a DOS external command should be in your path (DOS).
-
- Second- I recommend that you TEST pkpress on a sample subdirectory
- to insure system compatibility.
-
- Warning- Make sure that you do not process any archives OF pkzip.
- For example if you have pkzip 1.1 zipped up for backup
- or for available download, change the extension from ZIP
- temporarily. Self-extracting files are OK (most pkzip
- archives are) - they will automatically recognized.
-
- Pkpress is a command line utility that will increase your drive
- space. It's main function is to recompress files created with
- PKZIP with maximal compression. After you specify which directories
- to process, the program will uncompress each zip file, save the
- comment, volume label, and path information, if appropriate.
- It will then recompress the files using Pkzip's maximal compression.
- If the file has already been compressed with maximal compression,
- PKPress will let you know and it will skip the file -- this saves
- a lot of time, and after you use it the first time, even optimizing
- and entire drive won't take very long! It will only do those files
- that have been added since!
-
- This can save MEGABYTES of hard disk space. The program displays a
- status screen while processing that will let you know what is going on.
- The program will then tell you how much disk space was saved. There is
- an explanation of the status screen below. Version 1.7 can still be
- run from a batch file, because it exits to DOS automatically upon
- completion. For sysops, you can put this in your nightly event
- to process the new uploads directory, or the whole drive.
-
- --------------------------------------------------------------------------
- Usage is very simple:
-
- Type PKPRESS and the drive & directories you wish to process:
-
- pkpress c: - process drive c
-
- pkpress d:\dl01 - process directory dl01 and all directories
- underneath it on drive d:
-
- ---------------------------------------------------------------------------
-
- This program will work equally well with PKZIP 1.1 or 2.04g. However, if
- you use version 2.04g, you will have the added benefit of converting any
- 1.1 files to 2.04, which will save even more DISK SPACE.

-
- If you choose to use PKZIP 1.1, and PKPRESS comes across a 2.04g file,
- which 1.1 won't be able to unzip, it will give you the same message you
- get when 2.04 comes across a 2.04 with maximal compress - "File already
- has Max Comp" - and it will skip it.
-
- Status Screen Explanation:
-
- Current File : Zip File Processing Now
- Uncomp. Size : Size of this file, uncompressed
- Labels Stored : Was it zipped with -$ ?
- Paths Stored : Was it zipped with -rp ?
-
- Zips Uncompressed : The total amount of uncompressed space every zip
- file processed would take up.
-
- The rest is fairly self-explanatory.
-
-
- Compatibility : Pkpress will NOT work with 4DOS or DR DOS.
-
-
- If you use a CFG file for a registered version of PKZIP, you may want to
- know the command line parameters used by PKPRESS:
-
- Pkzip : --- -+- -)- -ex -m -vt -vb (-rp -$) <-- if necessary
-
- Pkunzip : --- -+- -)- (-$ -d) <-- if necessary
-
- If you use a configuration that you think may affect this, please consider
- changing it, temporarily at least. The program will override most normal
- configurations, but I guess it is possible to be affected by an off-the
- wall one.
