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 GunPaint file, with the extension .gun, is associated with the GunPaint image editing software, primarily used for pixel art and digital painting. This file type contains the project data, including layers, color palettes, and tool settings, enabling artists to save and revisit their work-in-progress. GunPaint is favored for its simplicity and effectiveness in creating detailed pixel art, making .gun files popular among game developers and digital artists focusing on retro and indie game graphics. The format supports various features tailored for pixel art creation, including pixel-perfect drawing, custom brushes, and animation frames.
