- 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 BLK file type is associated with the Amiga computer system, specifically within the context of the Interchange File Format (IFF), which was widely used on Amiga systems for various types of multimedia data. BLK files typically contain block data, which could be used for storing graphics, animation frames, or map tiles for video games and other graphical applications. The IFF format is a container format, meaning that it can hold various types of data structures, with BLK files being specifically tailored for graphical block data. These files were integral to the development and distribution of content for the Amiga platform, especially during its peak in the late 1980s and early 1990s.
