CPT files are used by amateur and professional photographers and graphic designers for storing touched up photos.

The CPT file is the main file type created by PHOTO-PAINT. When you save your image, PHOTO-PAINT creates the CPT file to store the image and all the edits that have been applied. CPT files are similar to the more popular Adobe Photoshop .PSD files in this way. You can save a CPT file by selecting File → Save.

The CPT file format is not supported by many image editors. However, you can export the file in PHOTO-PAINT to more widely supported image formats, such as .JPG, .PNG, .GIF, and .BMP. To export the CPT file select File → Export... and choose the format.
