.DA1 File Extension
What is a DA1 file?
Game file used by AGiliTy, an Adventure Game Toolkit (AGT) interpreter; contains general game data referenced by the AGT game as the player navigates through the story.
Interactive fiction games, such as AGT games, require the player to type commands in order to navigate through a story.
AGT games are packaged with a large variety of files. Each file contains game data, including .TTL, .INS, .and VOC files. Because of the large number of files that accompany the AGT game, the files can be converted into a single .AGX file with the AGT2AGX utility that comes with AGiliTy. This conversion reduces clutter, load time, and game size.
