- Description
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
- An image saved by Corel PHOTO-PAINT 7 or later (the file starts with CPT7FILE, CPT9FILE ...). It shares the .cpt extension with the older Corel PhotoPaint 6 format, and no converter here reads it yet.
