How to Upload a Save to Your Sons of the Forest Server

Transfer a local co-op or singleplayer world to your Sons of the Forest dedicated server.

You can upload a world from singleplayer, co-op, or another server to your dedicated server. Note that player-specific data (inventory, position, stats) does not transfer — only world data (structures, items on the ground, game progress).

Finding Your Local Save

On Windows, saves are stored at:

%AppData%\LocalLow\Endnight\SonsOfTheForest\Saves\<SteamID64>\Multiplayer\<SaveID>\

Each save folder contains a SaveData.zip and various .json files.

Server Save Structure

SaveData.zip

GameStateSaveData.json

ConstructionsSaveData.json

The folder name corresponds to the SaveSlot value in dedicatedserver.cfg (slot 1 = 0000000001, slot 2 = 0000000002, etc.).

Upload Your Save

Stop the server

Go to Console in the XGamingServer Panel and stop the server.

Back up the existing save (optional)

Go to Backups and create a backup before overwriting.

Navigate to the save slot

Click Files in the sidebar. Navigate to Saves/DedicatedServer/Multiplayer/. Open the folder matching your SaveSlot (e.g., 0000000001).

Upload save files

Delete the existing contents and upload all files from your local save folder.

Set SaveMode to Continue

Open dedicatedserver.cfg and ensure:

"SaveSlot": 1,
"SaveMode": "Continue"

SaveMode must be "Continue" — if set to "New", the server will overwrite your uploaded save.

Start the server

Start from Console. The server loads your uploaded world.

Starting a Fresh World

To generate a new world instead of uploading:

Set "SaveMode": "New" in dedicatedserver.cfg
Optionally change SaveSlot to keep the old save
Start the server — it creates a new world and auto-switches SaveMode back to "Continue"

Setting SaveMode to "New" overwrites any existing save in that slot. Use a different SaveSlot number to preserve the old world.
