Core Keeper stores its save files at %USERPROFILE%\AppData\LocalLow\Pugstorm\Core Keeper\Steam on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps every version, so a corrupted or overwritten save is one click from restored.
Where Core Keeper saves are stored
- Windows —
%USERPROFILE%\AppData\LocalLow\Pugstorm\Core Keeper\Steam
How to open the save folder
- Windows — press Win+R, paste
%USERPROFILE%\AppData\LocalLow\Pugstorm\Core Keeper\Steam, and press Enter (the AppData folder is hidden in Explorer, which is why this path is so easy to miss — pasting it skips the hunt).
Backing up Core Keeper saves automatically
- Install Checkpoint64 (free) and pick Core Keeper — the save path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.
