WWPACK is an executable compression utility for DOS, developed by Piotr Warezak and Rafal Wierzbicki. Its main feature is compression of EXE files.
See also WWPack32, a related utility for Windows.
Discussion
Version 3.00+ can also compress arbitrary data files. Such files are compressed using the "PD" command, and decompressed with "UD".
Version 3.03+ can also compress COM files, converting them to EXE.
The registered version of WWPACK v3.03+ has a "U" command, to decompress (some) executable files compressed with WWPACK.
No WWPACK versions prior to 3.00 have been found. Based on the 3.00 documentation, there were five such releases: 2.00 (1993-11-24), 2.01, 2.02a, 2.03, and 2.04. Prior to v3.00, WWPACK only compressed the DOS "relocation table". It became a full-fledged executable compression utility as of v3.00.
Identification
EXE files compressed by WWPACK probably have ASCII "WWP" at offset 28.
Data files compressed by WWPACK begin with "WWP".
Software
- WWPACK
Ed. note: The later versions of WWPACK will refuse to run unless the timestamp of the WWPACK.EXE file is exactly correct. For v3.04, it must be 1996-01-06 03:04:00am. For v3.04a, it must be 1996-01-21 03:04:00am.
