- 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.
- The PSF file format, standing for PhotoStudio File, is a proprietary image format developed by ArcSoft for use with their PhotoStudio image editing software. It is designed to save an image's data along with any layers, effects, or other editing details that have been applied, allowing users to save their work in progress and return to edit it further at a later time. Because it is a proprietary format, PSF files are primarily supported and can be fully edited only within ArcSoft PhotoStudio and possibly a few select other applications. For broader compatibility, users often convert PSF files to more widely recognized formats like JPEG or PNG after finalizing their edits.
