Subnautica Save File Location

Here's exactly where Subnautica stores your saves on PC, how to open the folder, and how to back them up.

Save file locations

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

Full path: C:\Users\<YourName>\AppData\LocalLow\Unknown Worlds\Subnautica\Subnautica\SavedGames\ . Each save is a slot folder named slot0000, slot0001, etc.

Steam (alternate)
Steam\userdata\<SteamID3>\264710

If Steam Cloud is enabled, a synced copy also lives in the Steam userdata folder under app ID 264710.

Xbox Series X|S / Xbox One
My games & apps > <Game> > Manage game > Saved data

Xbox saves sync automatically to the cloud with your Microsoft account; there is no user-accessible save file on disk.

Cloud saves

On PC, Subnautica uses Steam Cloud. If a cloud save and a local save conflict after offline play, choose the newer one when prompted so you don't lose exploration progress.

How to open the save folder

  1. Press Win + R to open the Run box.
  2. Type %userprofile%\AppData\LocalLow and press Enter.
  3. Open Unknown Worlds > Subnautica > Subnautica > SavedGames.
  4. Copy the whole save folder somewhere safe before editing, modding, or moving PCs.
