CMZ (official name unknown) is a compressed archive format. Its only known use is for distribution of some versions of Ami Pro. It may be a proprietary Lotus format.

Strings found in the companion COMPRESS.DLL file suggest it uses the PK Data Compression Library, so it probably has some similarities to ZIP.

Identification

Files apparently begin with ASCII "Clay".
