What is a CPT file?

A CPT file is a bitmap image created by Corel PHOTO-PAINT, a photo editing program included with CorelDRAW Graphics Suite. It contains an image that supports layers, alpha channels, transparency, and other effects. CPT files are the native files PHOTO-PAINT saves to store images users create or modify with the software.
