Where Are Titan Quest II Save Files Located?
Titan Quest II keeps Early Access saves in AppData Local under TQ2 Saved SaveGames, with Steam Cloud copies under userdata.
Last updated
Titan Quest II is Unreal based, so the PC build follows the engine layout: a TQ2 folder in local AppData, with saves nested under Saved SaveGames. Character files use long names ending in _Data_Player.sav and _Header.sav, plus a shared settings file.
Steam Cloud covers this folder, but Early Access threads are full of Cloud overwriting good local files after a crash. The practical habit is manual backups of the TQ2 folder before patches, and Cloud off while you restore a backup, then back on.
Where Titan Quest II stores this, by platform
%LOCALAPPDATA%\TQ2\Saved\SaveGames
Per character saves plus SharedGameSettings.sav. Back up the whole TQ2 folder, not single files, since headers and player data pair up.
<SteamLibrary>/steamapps/compatdata/1154030/pfx/
Proton prefix for app ID 1154030. The Windows TQ2 path is mirrored inside the prefix drive on Deck and desktop Linux.
Frequently asked questions
How do I back up Titan Quest II saves on PC?
Copy the whole TQ2 folder elsewhere while the game is closed. Paste it back to the same AppData path to restore. Keep Cloud on afterward so both copies agree.
My save vanished after a crash. What should I do first?
Turn off Steam Cloud for the game first, then restore your backup. Cloud sync has a history of clobbering local TQ2 files after crashes and patches in Early Access.
What are the _Data_Player and _Header files in SaveGames?
That folder holds per character progress plus shared settings. The .bak style files next to the .sav files are the game own recovery copies after failed writes.
