Empire at War
Game
Both are played from the same copy of the game: the folder or archive below holds them both. Each keeps its own saves. Mods are almost always made for Forces of Corruption, so running the original usually does not work with mods: turn them off below when you play it.
Commander
The name other players see in multiplayer. Kept in this browser.
Your game
This needs your own copy of Empire at War with Forces of Corruption (Steam or Gold Pack). Pick one way:
Installed game folder
The folder that holds GameData and corruption. It is read where it is each time
you play; nothing is copied.
Game archive
A copy of the game folder in one file, kept in this browser's own storage.
Mods optional
A mod's own folder, the one with Data in it. It is read from your disk each time you play;
nothing is copied or changed, and removing it here leaves the folder as it was. Mods are laid over the game in the
order shown, the last on top. A total conversion needs the whole game under it: the installed folder, or an archive of it.
