Disambiguation

Some format lists say there is a CPX/.cpx format, described as "CMX compressed", but evidence is lacking.

Corel says[1] that the Corel ArtShow 5 book+CD product used a CPX format. More research may be needed here.

Format details

CCX is based on RIFF, with some of the RIFF structure compressed inside a special "pack" chunk. It (usually?) uses zlib compression.

Identification

CMX files start with "RIFF", and have "CDRX" at offset 8.
