Claim your server
- Set the admin password. In your server's Settings, set the Admin password and press Save configuration. It claims the server for you.
- Add it in the game. In Satisfactory, open Server Manager from the main menu, add a server with the address and port from your dashboard, and sign in with that password.
Upload your save
- Open Manage Saves. In Server Manager, select your server and open Manage Saves.
- Upload the save. Choose to upload a save, and pick yours from the saves on your PC.
- Load it. Select the save and load it. Your factory is now the server's session.
Or use the file manager
Satisfactory keeps saves in %LOCALAPPDATA%\FactoryGame\Saved\SaveGames, in a folder named with a long number. Each .sav file is one save, and autosaves are numbered _autosave_0 to _autosave_2. Pick the newest.
Upload it in Files & SFTP to Saved/SaveGames (files up to 96 MB in the browser), or over SFTP to Saved/SaveGames/server. Then load it from Manage Saves.
