CCX (Corel)
From Just Solve the File Format Problem
Corel CCX is a vector graphics file format, used for example in the Corel Gallery 1 Million clip art collection. It is a compressed form of CMX (Corel Presentation Exchange).
See also Corel Gallery.
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.
