PACK (TurboPower)
From Just Solve the File Format Problem
- See Pack for other formats with that name.
PACK is a simple executable compression utility for 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: 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:
- exeutil.zip - Source code
- 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.
Sample files
- DSKCPY20.ZIP → DSKCOPY.EXE
- s_nws410.zip → *.EXE
- Shareware Grab Bag → 081/opcpnd26.arc → *.EXE
