Where Are Armored Core 6 Save Files Located?
Where Armored Core 6 keeps AC60000.sl2 saves per Steam account, in classic FromSoftware fashion.
Last updated
Armored Core 6 follows the FromSoftware house style: saves sit in an ArmoredCore6 folder under AppData\Roaming, with one subfolder per Steam account holding AC60000.sl2. Every build, arena rank and story checkpoint shares that single file.
The file has a silent sibling worth knowing: the game keeps its own backup copy beside the live save, same as Elden Ring does with .bak files. Copy the parent folder rather than the .sl2 alone and both travel together. Steam Cloud syncs the folder too, so pause it during manual restores.
Where Armored Core VI stores this, by platform
%APPDATA%\ArmoredCore6\[SteamID]\AC60000.sl2
Paste %APPDATA%\ArmoredCore6 into Explorer. The numbered folder is your Steam ID. Back up the whole folder with the game closed, and keep copies outside AppData where they cannot be mixed up with the live files.
Frequently asked questions
How do I back up my Armored Core 6 garage and progress?
Copy the whole ArmoredCore6 folder (or just your numbered ID folder) with the game closed. To restore, put it back and pause Steam Cloud until the game loads the files, then choose local files when asked.
There are several numbered folders. Which save is mine?
Match the subfolder name to your 64 bit Steam ID, or sort by modified date after quitting the game. Each account that played on the machine gets its own folder, so shared PCs hold several.
