'''WWPACK''' is an executable compression and file compression utility for DOS, developed by Piotr Warezak and Rafal Wierzbicki. It does executable compression of [[MS-DOS EXE|EXE]] files. It can also compress arbitrary data files.

Some of the files compressed by WPACK can be decompressed by WWPACK, using the "U" or "UD" option.

== Identification ==
EXE files compressed by WWPACK probably have ASCII {{magic|"WWP"}} at offset 28.

Data files compressed by WWPACK begin with {{magic|"WWP"}}.

 == Discussion ==
-Version 3.00+ can also compress arbitrary data files. Such files are compressed using the "<code>PD</code>" command, and decompressed with "<code>UD</code>".
+The WWPACK documentation is inconsistent about some things, such as which versions were released, the release date of v3.00, and which versions have the "<code>U</code>" decompression feature. The information here is based on evidence, and educated guesswork.
 Version 3.03+ can also compress [[DOS executable (.com)|COM]] files, converting them to EXE.
 The registered version of WWPACK v3.03+ has a "<code>U</code>" command, to decompress (some) executable files compressed with WWPACK.
