Corel Presentation Exchange (CMX) is a metafile format that supports bitmap and vector information and the full range of PANTONE, RGB, and CMYK colors. Files saved in CMX format can be opened and edited in other Corel Suite applications.

CMX adopts the Resource Interchange File Format (RIFF). The entire CMX file is enclosed within either the RIFF or RIFX form, depending on the platform.

Corel created the CMX format to serve as a proprietary image interchange format, which could be used to transfer images from any Corel program to another. For example, you could previously save an image as a CMX file in CorelDRAW and then import that image into Corel Presentations, for use on a slide.

However, many Corel programs no longer support the CMX format. For example, you cannot import a CMX file into current versions of Corel Presentations, WordPerfect, or PaintShop Pro.

How to open an CMX file

Another way to open CMX files on Mac or on iPhone without Corel products is to use CDRViewer. Here is a short instruction about how to use it.
