if you're ingame and want to go back to the autosave, you don't have to mess with explorer. once you're on the 'choose a game to load' screen, the directory structure is on the left. what it shows you as default are the games in the saves/single (player) directory. if you want the autosaves, you have to click directly on the + next to the "single" directory there on the left to expand it. /auto is a subfolder there. it's not like explorer, which shows both the files and the folders, so it wasn't intuitive to me.
