What is a .age3sav file?

An .age3sav file is a save game file created by the real-time strategy game Age of Empires III. It contains all the information needed to resume a previously played game, including player progress, unit positions, resource counts, and game state. These files allow players to pause their games and return to them later without losing their progress. While primarily used for saving single-player campaigns or skirmish matches, they can also be used for multiplayer game state.
