How to Transfer Your Subnautica Save to a New PC

Save file location

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

Copy the entire save folder from %USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\Subnautica\SavedGames on your old PC to the exact same path on the new PC — that folder is your whole Subnautica progress.

Back up first (Windows) — copy & run

Before you move anything, make a full backup of every Subnautica save on the OLD PC in one command. Press Win+R (or open Command Prompt), paste this, and hit Enter:

robocopy "%USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\Subnautica\SavedGames" "%USERPROFILE%\Desktop\Subnautica-save-backup" /E /COPY:DAT /R:1 /W:1

/E mirrors the whole save tree (every profile sub-folder and slot) to a backup folder on your Desktop without touching the originals. Copy that folder to the new PC, then restore by swapping the source and destination paths.

Move your Subnautica save to a new PC — the exact folder to copy, cloud-sync notes, and the mistakes that lose progress.

How to transfer your Subnautica save to a new PC

On the old PC, press Win+R, paste %USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\Subnautica\SavedGames, and press Enter to open the Subnautica save folder.
Select everything inside that folder and copy it to a USB drive, a cloud folder (OneDrive/Google Drive), or a network share.
Install Subnautica on the new PC and launch it once, then quit — this creates the empty save folder so the path exists.
On the new PC, open the same path (%USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica\Subnautica\SavedGames) and paste the copied files in, overwriting if asked.
Launch Subnautica and confirm your progress loaded before deleting the backup copy.

Does cloud sync move it for you?

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.

Common mistakes

Copying only a single save file instead of the whole folder — many games keep settings, profiles, or rolling backups alongside the main save.
Forgetting to launch Subnautica once on the new PC first, so the destination folder doesn't exist yet when you paste.
