Subnautica Save File Location (Windows)

Subnautica stores its save files at %USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\SavedGames 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 Subnautica saves are stored

  • Windows — %USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\SavedGames

The save data here is .json / .bin / .dat / .png / .jpg files — back up the folder as a set, not single files, so a restore always keeps them consistent.

How to open the save folder

  • Windows — press Win+R, paste %USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\SavedGames, 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 Subnautica saves automatically

  1. Install Checkpoint64 (free) and pick Subnautica — the save path above is already preset.
  2. Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
  3. Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.
