There is only one file type that uses the .W3Z extension:
Warcraft 3 Saved Game File
Mission save file created by Warcraft III and the Warcraft III Frozen Throne expansion pack; saves current progress and allows the game to be loaded and continued at a later time.
Multiplayer games (such as Battle.net matches) can be saved as well. However, each user must load the saved game in order for the match to be resumed correctly.
