There is only one file type that uses the .AGE3SAV extension:
Age of Empires 3 Save File
Save file used by Age of Empires 3 (AoE3), a real-time strategy game; contains saved game progress, such as experience level and unlocked units, which the player can load to resume gameplay.
AGE3SAV files should be placed in the \My Documents\My Games\Age of Empires 3\Savegame\ directory.
The Age of Empires 3: The WarChiefs expansion uses the .AGE3XSAV extension for save files. The second expansion, Age of Empires 3: The Asian Dynasties, uses the .AGE3YSAV file extension. The two expansions are now included in one collection, which is accessible through the link below.
