What is an AGG file?

An AGG file is a game data archive used by various games, including Heroes of Might and Magic and Heroes of Might and Magic II, turn-based strategy games developed by New World Computing. It contains images, audio files, and other assets required to play the game. The game automatically loads AGG files, but users may attempt to open them to modify the assets.

More Information

While various PC games developed by New World Computing, Inc. use AGG files, they are most commonly associated with Heroes of Might and Magic and Heroes of Might and Magic II. The first version of Heroes of Might and Magic debuted in 1995, and the second version debuted in 1996. If you have access to the original games, you can find AGG files in the installation directory of the games.

NOTE: New World Computing, Inc. eventually transferred the rights to the Heroes of Might and Magic franchise to Ubisoft in 2003.

How to open an AGG file

You should not attempt to manually open an AGG file since it may corrupt the assets and cause the game not to load correctly. Instead, the game automatically loads the AGG file.

However, some game modders looking to change resources may extract them from an AGG file with Watto Studios Game Extractor (multiplatform).
