WHAT IS TCM?
Since PKWARE released PKZIP v2.04, PKZIP has one of the best, if not
THE best, compression routines (ie. the resulting archive is the
smallest in size) - beating both ARJ and LZH. Unfortunately, most
PKZIP users use the default Normal Compression option to zip their
files, thus not fully realizing the advantage that PKZIP 2.04 provides.
By converting all your zipfiles to Maximum Compression, you can
dramatically decrease the size of your archives.
TCM is a utility that allows people who use PKZIP 2.04g to safely and
efficiently convert all .ZIP files to Maximum Compression, thus saving
valuable hard disk and backup media storage space. If you constantly
work with and backup a large number of zipfiles, then TCM is for you!
FEATURES:
- Run unattended from batch files
- Verify integrity (CRC error-free) in zipfiles before processing
- Test zipfiles and then convert to Maximum Compression if necessary
- Convert ANY zipfile including those zipped with PKZIP 1.10 and prior
- Volume Labels and stored paths within zipfiles processed safely
- Hidden and System files within zipfiles processed safely
- Delete ANY unwanted files from your zipfiles through a text list
- Insert or remove Zip Comments from zipfiles
- Insert a file of your choice to zipfiles
- Add Authenticity Verification (-AV) stamp on zipfiles
- Strip -AV signature from zipfiles if you choose 'No' -AV stamping
- Use McAfee's SCAN on zipfiles to scan for virus
- Complete configurability for the above options
- Display statistics of processed files
- Process files across LAN networks
REQUIREMENTS:
- 286/386/486/Pentium systems
- DOS 3.30 and above
TCM was tested extensively on DOS-based systems as well as LAN
networks (using Ethernet and LANtastic AI 5.0) and proven to work
reliably. I do not use OS/2 or Windows on my systems so TCM may
not be compatible with either.
- Free hard disk space of 5 times the largest zipfile you are processing
(ie. if the largest zipfile you are processing is 1 mb in size, then
you will need at least 5 mb of free hard disk space)
(Mandatory):
- PKZIP.EXE and PKUNZIP.EXE version 2.04g from PKWARE, Inc.
- STRIPAV.EXE (supplied with TCM archive)
- PRUNE.COM (supplied with TCM archive)
(Optional):
- Registered copy of PKZIP version 2.04c (if you want -AV stamping)
- SCAN.EXE from McAfee Associates (if you want virus scanning)
USAGE:
TCM <Enter> <-- when in active directory where zipfiles are to
be processed.
or
TCM [drive:path] <-- process zipfiles located in the specified dir.
Example:
TCM c:\files\dwnld
LOCATION OF FILES:
(Mandatory)
- The following files should be located in a directory defined in your
PATH statement located in your AUTOEXEC.BAT file:
∙ PKZIP.EXE version 2.04g
∙ PKUNZIP.EXE version 2.04g
∙ SCAN.EXE latest version (if you activate the SCAN feature)
- The two external utilities included with the TCM distribution archive,
STRIPAV.EXE and PRUNE.COM, may be placed in any directory of your
choice.
- TCM.EXE and TCMSETUP.EXE may be placed in any directory of your choice
as long as they are in the same directory.
(Optional)
- A text file containing a list of filenames that you want TCM to delete
unwanted files. This file should be in the format of one filename per
line. Filename and path defined by you in TCMSETUP.
- A file that you would like TCM to insert into processed zips. Can be
text or binary. Filename and path defined by you in TCMSETUP.
- A small text file to be included as zip comment (headers) in your
zipfiles. This must be a plain text file, no ANSI characters.
Filename and path defined by you in TCMSETUP.
CONFIGURING TCM:
*** TCMSETUP will abort if it fails to locate the necessary files
during setup!
Make sure you've placed all the files listed above in their appropriate
directories >before< you run TCMSETUP.
Detailed explanation of each option is displayed during setup.
REGISTRATION/DISTRIBUTION:
No registration is necessary. TCM is FREEWARE and may be used and
distributed freely.
However, the sale of TCM for profit, either alone or together with
other software or hardware is prohibited without prior permission
from the author.
Any software dealer or library may distribute the entire TCM package
in unmodified form for a fee as long as the price charged for the disk
containing TCM does not exceed US $5.00.
FUTURE DEVELOPMENTS:
Upcoming release of TCM will include the ability to:
- Convert LZH and ARJ files to ZIP format
- Use of EMS/XMS to reduce memory requirements
- Recognize a single filename passed in the command line to TCM
so that BBS sysops can use TCM to process uploads from their BBS

A few words from the author:
This utility was written out of necessity. I found myself constantly using
several archive shells and ZIP utilities to process files uploaded to my
Bulletin Board System and it became more and more time consuming as the
number of files increased. As a result, a crude version of TCM - version
0.10α, was written to automate this mundane task. Several brave users on
my BBS tested it and encouraged me to release it to the public. Thanks to
them, you now have the finished product.
TCM merges the features found in several utilities and improved on them.
While TCM will be most beneficial to sysops, non-sysops can undoubtedly put
it to good use too. Converting all your zipfiles to Maximum Compression will
definitely save you substantial amounts of storage space in the long run.
You can configure TCM to work on your zipfiles in any desired manner. For
example, sysops might choose to insert an ad file, add their zip comments
and strip all AV signature while non-sysops might choose to strip all their
files of unnecessary ads, zip comments, etc. and still convert everything to
Max Compression.
