More than a few times in the past, users of my DirX program have contacted
me asking about the availability of some of the compression utilities
mentioned in DIRX.DOC, or alluded to in the sample DIRX.CFG files I've been
including in my distribution archives for DirX (DRX???.ZIP).
Below I've incorporated, in database form, information on those utilities,
plus a few more, which I've gleaned from various sources. By no means do I
make any warranty that the information is completely accurate, or
up-to-date. The authors of any of the below mentioned programs,
especially, are welcome to contact me with more timely information.
For each program listed below I indicate:
1) the main program filename
2) the most recent version number of which I have personal knowledge, and,
as far as I could determine, either the program date, or the earliest
file date (not necessarily reliable)
3) whether or not it is intended to be used with .COM, .EXE and data files
4) the author, or owner, of the program
5) how the program is distributed: public domain, freeware, shareware or
commercial.
6) if available on CompuServe, then which forum and library carries a copy
of the distribution archive, and the filename(s) of the archive(s)
(there may be other forums on CIS which make the programs available, but
I just list the ones with which I'm most familiar)

PROGRAM: PKLITE.EXE v1.14, 06/01/92
.COM: Yes
.EXE: Yes
DATA: No
AUTHOR: PKWARE, Inc.
DISTR: Shareware
CIS LIB: lBMSYS/Lib 6
ARCH NAME: PKLITE.ZIP
PROGRAM: TINYPROG.EXE v3.5, 04/27/92
.COM: Yes
.EXE: Yes
DATA: No
AUTHOR: Tranzoa, Co.

CIS LIB: IBMSYS/Lib 6
ARCH NAME: TINY35.ZIP
TINYPROG compresses .EXE and .COM files while leaving them executable.
TINYPROG'ed programs check themselves for correctness - so that a corrupted
program will not run. TINYPROG'ed programs can be password protected.
Software developers can easily include self-configuration information with
TINYPROG'ed programs.
PROGRAM: DIET.EXE v1.44, 01/22/92
.COM: Yes
.EXE: Yes
DATA: Yes
AUTHOR: Matsumoto, Teddy

This is PKLITE Professional. The main *functional* difference between it
and the shareware version seems to be the extra-compression option (-e
switch), which produces "unextractable" compressed files. Executable files
created by PKLITE Professional can be used and distributed for commercial
use.
PROGRAM: LEXEM.EXE v0.93, 11/15/90
.COM: Yes
.EXE: Yes
DATA: Yes
AUTHOR: Matsumoto, Teddy
DISTR: Freeware
CIS LIB: n/a
ARCH NAME: n/a
Calling this utility an executable file compressor may be doing it an
injustice. It may be loosely described as an archiver-type utility with
the added capability of functioning as an executable file compressor. The
first version of DIET appeared to be a stripped-down version of LEXEM, with
only the executable file compression features left in.
PROGRAM: LZEXE.EXE v0.91, 12/24/89
.COM: No
.EXE: Yes
DATA: No
AUTHOR: Bellard, Fabrice
DISTR: Public Domain
CIS LIB: IBMSYS/Lib 6
ARCH NAME: LZEX91.ZIP
I've only seen two public releases of this utility, Versions 0.90 and 0.91.
I've read that the author has sold his rights to the program, so don't look
for any future public domain releases of LZEXE.

Formerly bundled with Microsoft's language products. The equivalent of
EXEPACKing is now available as an option to Microsoft's LINK utility.

.COM: Yes
.EXE: Yes
DATA: Yes
AUTHOR: Kaya, Raymond T.

CIS LIB: IBMSYS/Lib 6
ARCH NAME: DRX109.ZIP
Shell for detecting files compressed by several executable file compressors.
Employs external compressors and uncompressors (user-selectable) to
transparently compress and uncompress files from within the program.
Currently supported are AXE, DIET, EXEPACK, ICE, LEXEM, LZEXE, PKLITE,
SCRNCH, SHRINK and TINYPROG. New: DIRX.CFG may now include command-line
switches.
PROGRAM: DIRXC.EXE v1.08, 01/01/92
.COM: Yes
.EXE: Yes
DATA: Yes
AUTHOR: Kaya, Raymond T.
DISTR: Freeware
CIS LIB: IBMSYS/Lib 6
ARCH NAME: DRXC10.ZIP
Smaller, simpler version of DirX for when you just want a listing of
compressed and uncompressed files. Listing is redirectable to printer or
file. Mimicks DOS's DIR command, to an extent. No sorting is performed.
New: Extends recognition of files compressed with LZEXE (hacked headers)
and DIET (additional headers).
PROGRAM: CHK4COMP.EXE v3.60, 12/07/91
.COM: Yes
.EXE: Yes
DATA: No
AUTHOR: Land, John
DISTR: Public Domain
CIS LIB: IBMSYS/Lib 6
ARCH NAME: CHK4.ZIP
Shows which .EXE & .COM files have been compressed by PKLITE, LZEXE, DIET,
AXE, LEXEM, TINYPROG, SHRINK, EXECUTRIX, SCRNCH, ICE, or EXEPACK, plus ID's
WINDOWS .EXE files, overlay files, & misnamed .EXE & .COM files. Output
sortable & redirectable. Subdirs. can be looped thru. NEW: shows extra
comp. for PKLITE files, and properly shows PKLITE vers. 1.03 files.
PROGRAM: UPACKFIX.EXE vn/a, 07/10/91
.COM: No
.EXE: Yes
DATA: No
AUTHOR: Piotrowski, John F.
DISTR: Freeware
CIS LIB: IBMSYS/Lib 6
ARCH NAME: UPACKF.ZIP
Purports to patch Bellard's original UPACKEXE.EXE utility to allow it to
decompress files compressed in the newer EXEPACK formats.
PROGRAM: UNLZEXE.EXE v0.5, 05/17/90
.COM: No
.EXE: Yes
DATA: No
AUTHOR: Kurizono, Mitsugu(Kou),
DISTR: Public Domain
CIS LIB: IBMSYS/Lib 6
ARCH NAME: UNLZEX.COM
Although the purpose of this program is to uncompress files previously
compressed by either version of LZEXE, in most cases you don't get an exact
replica of the original .EXE file, just a functional equivalent. If you
choose to compress your executables with LZEXE, it may be prudent to back up
the originals first. (This is true for executable file compressors in
general, but *especially* true for LZEXE.)
PROGRAM: UPACKEXE.EXE v1.00, 01/02/90
.COM: No
.EXE: Yes
DATA: No
AUTHOR: Bellard, Fabrice
DISTR: Public Domain
CIS LIB: IBMSYS/Lib 6
ARCH NAME: LZEX91.ZIP
This was a utility distributed with Version 0.91 of LZEXE, which was
intended to be used to unpack files compressed with EXEPACK.
Unfortunately, it didn't always recognize, and therefore didn't work with,
all "EXEPACKed" files. However, recently, a utility has been made
available to patch UPACKEXE.EXE (see UPACKFIX.EXE).

By the time you read this, it's conceivable that later versions of these
programs will be made available. If you attempt to search for any of these
files on CompuServe, please be aware that the names of distribution
archives which incorporate version numbers may change, if a later version
is uploaded. Thus, if a first attempt doesn't turn up the names I've shown
above, you might try using the wildcard character '*' in place of the
embedded version number. Example: If you can't find 'PKL113.EXE', you
might search for the filespec 'PKL*'. You could also search on an
appropriately chosen KEYWORD - 'DIET' for DIET-related files, for example.
If all else fails, you might simply ask in the appropriate forum.
