How to Transfer Your Fallout 3 Save to a New PC

Switching computers? Here's exactly which Fallout 3 save files to copy, where they live, and how to make sure your progress loads on the new PC.

Quick answer
%USERPROFILE%\Documents\My Games\Fallout3\Saves

Copy the whole Saves folder — the .fos files are your saves and there is no cloud backup.

Where the files live: see the full Fallout 3 save file location guide for every platform path (PS5, Xbox, Steam Cloud).

How to transfer your Fallout 3 save to a new PC

  1. On the old PC press Win+R, type %USERPROFILE%\Documents and press Enter.
  2. Open My Games > Fallout3 > Saves and copy all the .fos files to a USB drive or cloud folder.
  3. Install Fallout 3 on the new PC and launch it once, make a save so the folder is created, then close the game.
  4. Open %USERPROFILE%\Documents\My Games\Fallout3\Saves on the new PC and paste your .fos files in.
  5. Launch the game and load a save to confirm it worked before deleting the backup.

Does cloud sync move it for you?

No — Fallout 3 does not use Steam Cloud, so the .fos files live only on your PC. You must copy them by hand; nothing is backed up automatically.

Common mistakes

FAQ

How do I move my Fallout 3 save to a new PC?

Copy the save folder at %USERPROFILE%\Documents\My Games\Fallout3\Saves from the old PC to the exact same path on the new PC, then launch the game. Use a USB drive, cloud storage, or a network share to move the files.

Will Fallout 3 cloud saves transfer automatically?

No — Fallout 3 does not use Steam Cloud, so the .fos files live only on your PC. You must copy them by hand; nothing is backed up automatically.

Where is the Fallout 3 save folder on the old PC?

It's at %USERPROFILE%\Documents\My Games\Fallout3\Saves. Paste that into the File Explorer address bar (or Win+R) to open it. See our full location guide for every platform.

Do I need to copy any other files?

Copy the whole save folder, not just one file — Fallout 3 may store settings, backups, or profile subfolders alongside the main save. Copying the entire folder avoids missing anything.
