The BPM Studio program from ALCATech also uses the GRP file extension. The program is used to reference and manage audio files in the system. Files with the file extension .grp are used to store the play list archives. Files with the .grp file extension can be used to index music files and create lists of music that can be played.
A GRP file is a game data file used by games that are built with Ken Silverman's Build Engine. Example games include Duke Nukem 3D and Shadow Warrior. GRP files can store various kinds of game data, such as graphics, audio, and map information. They are saved in a simple uncompressed format and therefore can easily be modified to change gameplay.
