Steam doesn't have one save folder. A Steam game keeps your saves wherever its developer decided, and that comes down to three places: the game's own folder in Documents or AppData, Steam's userdata folder under your account ID, or the game's install folder. Checkpoint64 knows which one each supported game uses, and backs it up automatically.
1. Documents or AppData (most games)
Most games save exactly where they would if you'd bought them anywhere else: a folder of their own in Documents, %APPDATA% or %LOCALAPPDATA%. Steam is just the launcher, which is why moving a game to another Steam library never touches these saves, and why they survive an uninstall.
AppData is hidden in Explorer. Press Win+R, type %APPDATA% or %LOCALAPPDATA%, and press Enter to go straight there. Every game in the catalog has a page with its exact folder.
2. Steam's userdata folder
Games built on Steam's cloud storage keep saves inside Steam itself, in a folder per account:
C:\Program Files (x86)\Steam\userdata\<account ID>\<app ID>\remote
<account ID>is a number. There's one folder for each Steam account that has signed in on the PC. Ignore0andanonymous: they're on nearly every install and never hold an account's saves.<app ID>is the game's number on Steam, the one in its store page URL:store.steampowered.com/app/<app ID>/.
To find your folder, open each numbered folder and look for the game's app ID inside. Only an account that has played the game has one, which is also how Checkpoint64 picks the right account when several share a PC.
If Steam isn't installed in the default place, userdata sits inside wherever you installed it.
3. The game's install folder
A few games write saves next to their own files, inside a Steam library:
C:\Program Files (x86)\Steam\steamapps\common\<game folder>
A library doesn't have to live in the Steam folder. If you added one on another drive in Steam → Settings → Storage, the game and its saves are under that drive's SteamLibrary\steamapps\common. To open the right one, right-click the game in your library and choose Manage → Browse local files.
These are the saves most at risk, because uninstalling a game deletes its install folder, saves and all.
Games that save inside Steam's folders
Every supported game that keeps its saves in userdata or in its install folder, with the part of the path below the Steam folder. Each one links to its full save location page.
| Game | Folder inside Steam |
|---|---|
| 007 First Light | userdata\<account ID>\3768760 |
| Black Mesa | steamapps\common\Black Mesa\bms\save |
| Black Myth: Wukong | steamapps\common\BlackMythWukong\b1\Saved\SaveGames |
| Crimson Moon | userdata\<account ID>\4317690\remote |
| Darkest Dungeon | userdata\<account ID>\262060\remote |
| Monster Hunter Wilds | userdata\<account ID>\2246340\remote\win64_save |
| OMORI | steamapps\common\OMORI\www\save |
| Onimusha: Way of the Sword | userdata\<account ID>\3974650\remote\win64_save |
| Pragmata | userdata\<account ID>\3357650\remote\win64_save |
| Resident Evil Requiem | userdata\<account ID>\3764200\remote\win64_save |
| S.T.A.L.K.E.R.: Call of Pripyat | steamapps\common\Stalker Call of Pripyat\_appdata_\savedgames |
| Subnautica | steamapps\common\Subnautica\SNAppData\SavedGames |
Linux and Steam Deck
On Linux, Steam's folder is ~/.steam/steam, so userdata is at ~/.steam/steam/userdata. The Flatpak build keeps its own copy under ~/.var/app/com.valvesoftware.Steam/.local/share/Steam.
Most games on a Steam Deck are Windows games running through Proton, and each one saves inside its own prefix: steamapps/compatdata/<app ID>/pfx/drive_c/users/steamuser, then the same subfolder it would use on Windows. The Steam Deck save file location post walks through finding one. For games that save to Documents or AppData, Checkpoint64 works out the prefix path from the Windows location, so you don't have to look up the app ID.
What about Steam Cloud?
Steam Cloud syncs a game's saves between your PCs, when the developer has switched it on. It doesn't cover every game, and it syncs whatever is newest, a save that just got corrupted included. The Steam Cloud alternative guide covers what that means in practice.
Backing up Steam saves automatically
- Install Checkpoint64 and pick the game. Presets for 140+ games already know which of the three places it saves to, account folder included.
- Leave auto-backup on. Every 60 seconds it checks the folder for changes and uploads a new version. Only changed files are sent.
- Restore any version in one click after a corruption, an overwrite or an uninstall, on this PC or another one you're signed in on.
