Description
The GEM (Graphical Environment Manager) Paint file type, with the extension .gem, originates from Digital Research's Graphical Environment Manager, which was an early graphical user interface for computers. These files are specifically used to store bitmap images created or manipulated within the GEM Paint application. GEM Paint provided users with basic tools for creating and editing images, much like early versions of Microsoft Paint. The .gem file format is primarily associated with the GEM desktop environment that was popular in the mid-1980s for PCs running CP/M and later on the Atari ST series of computers.
