Satisfactory: Uploading & Downloading Saves

One of the best features of **Satisfactory** is the ability to seamlessly move your world between Singleplayer and a Dedicated Server. Whether you want to upload your 500-hour factory to play with friends or download the server save to fix a bug in SCIM, this guide covers the process.

1. The Server Directory

On Linux servers (Supercraft), saves are located at: /.config/Epic/FactoryGame/Saved/SaveGames/server/.

2. The Local Directory

On your Windows PC, saves are at: %localappdata%\FactoryGame\Saved\SaveGames\[YourSteamID]\.

3. Session Names

The server tracks the "Session Name". Do not rename the .sav file drastically, or the server might create a new session instead of loading the old one.

Method 1: Using the In-Game Server Manager (Easiest)

Coffee Stain Studios built a transfer tool directly into the game menu.

  1. Open Satisfactory and click Server Manager.
  2. Select your server from the list.
  3. Go to the **Manage Saves** tab.
  4. To Upload: Click "Upload Save" -> Select your singleplayer world -> Click Upload.
  5. To Download: Select the save in the server list -> Click "Download Save".

Method 2: Manual FTP Transfer (Faster for Large Saves)

If your save file is 20MB+, the in-game uploader often times out. Use FTP instead.

  1. Open **FileZilla** or your Supercraft **File Manager**.
  2. Navigate to /.config/Epic/FactoryGame/Saved/SaveGames/server/.
  3. Upload: Drag your .sav file from your PC into this folder.
  4. Download: Drag the latest autosave_0.sav from the server to your PC.
  5. Critical Step: After uploading manually, you must go to the Server Manager -> **Load Game** tab and select the new file to load it.

Troubleshooting "Offline" Status

Sometimes, after uploading a save, the server appears "Offline" in the manager even though it is running.

  • Wait 5 Minutes: Large factories take time to deserialize (load into RAM). The server cannot reply to queries while it is loading the map.
  • Check Logs: If it stays offline for 10+ minutes, check the console for "Crash" or "Out of Memory" errors. The save might be too big for your RAM plan.

Pro Tip: Always rename your save before uploading it (e.g., MyWorld_Dedicated.sav). This helps you distinguish it from the server's auto-generated autosave_0 files later.

Your factory, everywhere. Host your Satisfactory server with Supercraft and utilize our high-speed FTP uplink for instant save transfers.
