CMZ (official name unknown) is a compressed installer-archive format. It was used by Ami Pro, and a few other Lotus or Samna products.

It uses PKWARE DCL Implode compression.

A CMZ file is a sequence of one or more member file segments, each of which consists of a signature, then a header, then the compressed data.

Files begin with ASCII "Clay".
