Valheim: Uploading Your World
Moving a world from your PC (Local) to a Dedicated Server allows your friends to play 24/7 without you being online. Before Valheim 1.0, the save was two files; in 1.0 it is a complete world folder. Upload the format your local save uses as one unit.
Not sure which world file is which? For a legacy save, drop your .fwl into the free Valheim World & Modpack Doctor. A 1.0 save is the complete folder containing the _main.<n>.fwl2 and matching data files. The tool reads legacy metadata in your browser (nothing is uploaded), so you can confirm the world before you touch the server.
1. The Save Format
Before 1.0, a world consists of Name.db and Name.fwl; upload both. In 1.0, upload the whole Name/ folder, including one complete matching _main.<n> generation and its .ok marker. Do not split the folder into individual files.
2. Cloud vs Local
If you use Steam Cloud, your saves are in a hidden specific userdata folder. If you move them to "Local" in-game, they appear in AppData.
3. Server Name
The server must be told exactly which world name to load. If the name doesn't match the file, it will generate a new empty world.
Step 1: Locate Your Local Files
Option A: Using "Move to Local" (Recommended)
- Open Valheim on your PC.
- Go to **Manage Saves**.
- Select your world and click **Move to Local**.
- Close the game.
- Press
Win + Rand type:%userprofile%\AppData\LocalLow\IronGate\Valheim\worlds_local. - You should see either
MyWorld.dbandMyWorld.fwl(legacy), or aMyWorld/folder containing the_main.<n>.fwl2,.db2,.chunksand.okfiles (1.0).
Option B: Steam Cloud (Legacy)
- Path:
C:\Program Files (x86)\Steam\userdata\[YOUR_STEAM_ID]\892970\remote\worlds\. - Note: We strongly recommend moving to Local first to ensure you have the latest version.
Step 2: Upload to Server
- Stop your Supercraft Server.
- Open **File Manager**.
- Navigate to:
/.config/unity3d/IronGate/Valheim/worlds_local/.
(Note: older servers might use just/worlds/, check both). - For a 1.0 save, upload the complete
MyWorld/folder. For a legacy save, upload bothMyWorld.dbandMyWorld.fwl.
Step 3: Activate the World
- Go to the **Startup** tab in your panel.
- Find the **World Name** variable.
- Change it to match the world name EXACTLY (case-sensitive, no extension).
Example: if the save isVikings.dbandVikings.fwl, or a folder namedVikings, enterVikings. - Save and Restart.
Common Error: A 1.0 folder that is missing its matching .db2, .chunks or .ok file is incomplete and will be refused. Let the local game finish saving, then upload the complete folder again. For a legacy save, a world with terrain but no buildings usually means the .db file failed to upload or is corrupt.
