CMX (Corel Presentation Exchange, also known as Corel Metafile Exchange) is a vector graphics format associated with Corel software such as CorelDRAW. It is designed for portability, at the expense of features. CMX is based on RIFF or RIFX.

There is apparently also a compressed form of CMX known as CPX.
