EXEPACK is an executable compression utility for DOS-style EXE files. It was developed by Microsoft, and originally written by Reuben Borman.
There are multiple versions of it, which differ in some of the technical details that need to be dealt with to restore compressed files to their original form.
Some of the EXE files included with some versions of MS-DOS were compressed with EXEPACK.
Identification
The strings "RB" and "Packed file is corrupt" usually appear somewhere in the file.
