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.

When you save an image with PHOTO-PAINT, the application creates the CPT file, by default, to store the image and all the edits you have applied. After saving the CPT file, you can close it and re-open it to apply future edits.
