The GG file type is associated with Koala Paint, a graphics program specifically designed for use on early home computers. It represents a compressed format used to store images created or edited within the Koala Paint software. This format allows for efficient storage by reducing the file size, making it easier to manage and share graphical data on systems with limited storage capacity. The GG extension is primarily recognized and used by vintage computing enthusiasts who engage in the preservation or emulation of classic computer systems and their software.
A BMP file is an uncompressed raster image comprised of a rectangular grid of pixels. It contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color.
