CMX stands for Corel Metafile Exchange Image File, it was a proprietary file format designed and used by the famous software company Corel Corporation. The CMX extension was used mostly in Corel's vector editing program, CorelDRAW or their image editing software CorelPaint. The CMX file not only contained the image but the data within the image which allowed stored information to be communicated between different software that could read that information.
