Skip to main content
A Sons of the Forest server keeps each world in a numbered save slot, and the Save Slot variable on the Startup page picks which one it loads (default 0000000001). To start a new world, set Save Slot to an unused number such as 0000000002 and restart. To play your own world on the server, upload its files into the slot’s folder in serverconfig/Saves/DedicatedServer/Multiplayer/.

​
Where are the saves on the server?

In Files, the worlds are in:
Each world is a folder named after its slot, for example 0000000001. The server saves automatically every 10 minutes by default (SaveInterval 600 in dedicatedserver.cfg).

​
How to start a new world

1

Back up your server

Open Backups and click Create backup.
2

Pick a new slot

Click Startup and set Save Slot to a number you haven’t used, for example 0000000002. The field saves when you click away.
3

Choose the difficulty (optional)

Set Gamemode for the new world. See change difficulty.
4

Restart

Restart the server. It creates a new world in the new slot. Your old world stays in its folder.

To switch back, set Save Slot to the old number and restart.

​
How to upload your save from your PC

1

Find your save on your PC

Open this folder in Windows Explorer:
Each subfolder with a long number is one world. Pick the one you want (check the modified date).
2

Stop the server and back it up

Stop the server, then create a backup in Backups.
3

Open the slot folder

In Files, go to serverconfig/Saves/DedicatedServer/Multiplayer/ and open the folder of the slot you want to use, for example 0000000001. If it doesn’t exist yet, click New folder and create it.
4

Upload the files

Click Upload and upload everything inside your save folder (its contents, not the folder itself). Replace the files that are already there. For many files, SFTP is quicker.
5

Check Save Slot and start

On Startup, make sure Save Slot matches the slot folder you used. Start the server.
A singleplayer save is in the Singleplayer folder next to Multiplayer. Load it once as the host of a multiplayer game on your PC and save there first, then upload the new save from Multiplayer.

​
Frequently asked questions

​
Can you have multiple saves in Sons of the Forest?

Yes. Each slot is a separate world. Only the slot in Save Slot runs, and you switch by changing the number and restarting.

​
How do I save the game on the server?

The server saves every 10 minutes. Set SaveInterval in dedicatedserver.cfg to change that. See dedicatedserver.cfg explained.

​
How do I wipe the server?

Start a new slot as above. To delete a world for good, delete its slot folder in Files after a backup.

​
Do players keep their items in an uploaded save?

The world comes across, but the character of the player who hosted the game on their PC may not. Give that player’s important items to a friend before you upload, and keep your local save until you have tested the server.
