File saved by Opterecenja, a program used for creating construction project plans based on weather elements such as snow and wind; saves various parameters used for producing output values; used for calculating structural load, which can also be plotted visually in the software.
NOTE: The Opterecenja software and website are localized in the Croatian language. The word "Opterecenja" is the Croatian word for "load."
Game file used by AGiliTy, an Adventure Game Toolkit (AGT) interpreter; contains story data referenced by the AGT game as the player navigates through the story.
To play interactive fiction games, which include AGT games, you must type commands to navigate through a story, similar to a choose-your-own-adventure book.
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.
Common OPT Filenames:
