:''See [[Pack]] for other formats with that name.''

'''PACK''' is a simple executable compression utility for [[MS-DOS EXE|DOS EXE]] files. It only compresses the relocation table.

It was developed by TurboPower Software and Kim Kokkonen. It was distributed as source code (Pascal and assembly language).

== Identification ==
Starting 10 bytes after the start-of-execution point (refer to [[MS-DOS EXE#Special file positions]]), the following byte sequence appears: {{magic|2e 8c 1e 06 00 2e 8c 06 08 00 8c c3 83 c3 10 8c}}.

For more details, look for "NewLoader" in the source code, noting that some of the first 10 bytes are not always the same.

== Software ==
PACK:
* {{CdTextfiles|swextrav1993/disk2/pascal/exeutil.zip|exeutil.zip}} - Source code
* [https://archive.org/details/tewi-power-programmierung tewi Power-Programmierung] → CD1.{mdf,mds} → pascal/utility/exepack/... - Source code variant, and DOS binary

Decompression:
* iCEuNP and TEU (refer to [[Executable compression#Decompression software]]) are examples of decompressors that may support PACK format.
