- 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 .geo file extension is associated with GeoPaint, a bitmap graphics editor originally developed for the Commodore 64 GEOS (Graphic Environment Operating System) in the mid-1980s. GeoPaint files contain bitmap images created or edited within the program, supporting a resolution of 320x200 pixels on the Commodore 64. These files enable users to create detailed graphics and illustrations with the limited color palette available on the Commodore 64. Despite its vintage nature, the .geo format remains a nostalgic reminder of early personal computing and digital art creation.
