What is .AGX file extension?
Game file used by Adventure Game Toolkit (AGT) interpreters such as AGiliTy; contains a game where you navigate through a story by typing commands; similar to .ZLB and .BLB Interactive Fiction (IF) game files.
AGT games are packaged with a variety of file extensions, such as .INS, .TTL, and DA1, that provide certain functions for the game. These files can be converted into a single AGX file with the AGT2AGX utility that comes with AGiliTy. This conversion reduces clutter, decreases load time, and increases portability.
