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. It requires moving two specific files.
Not sure which world file is which? Drop your .fwl into the free Valheim World & Modpack Doctor - it reads the world name, seed, and modifiers in your browser (nothing is uploaded), so you can confirm you are moving the right world before you touch the server.
1. The Two Files
A world consists of a Name.db (Database - terrain, buildings) and Name.fwl (File World Link - seed/metadata). You need **BOTH**.
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
MyWorld.dbandMyWorld.fwl.
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). - Upload both
MyWorld.dbandMyWorld.fwl.
Step 3: Activate the World
- Go to the **Startup** tab in your panel.
- Find the **World Name** variable.
- Change it to match your filename EXACTLY (case-sensitive, no extension).
Example: If file isVikings.db, enterVikings. - Save and Restart.
Common Error: If your world loads spread out terrain but NO BUILDINGS, it means the `.db` file failed to upload or is corrupt. Re-upload the `.db` file.
