How To Upload An Existing tModLoader World To Your Server

This guide covers how to upload an existing tModLoader world save file to your Terraria server.

You may also refer to our guide on how to upload files to your game server.

If you get stuck at any time, GhostCap offers free world transfers. Just reach out to us on Discord.

Finding Your Local tModLoader World Save File

1. Press Windows Key + R and enter this:

   %USERPROFILE%\Documents\My Games\Terraria\tModLoader\Worlds
   

2. Find both the .wld and .twld files for the world you want to upload.

The .twld file contains your modded world data and is required.

Your world save file location should look like this:

Documents/
└── My_Games/
    └── Terraria/
        └── tModLoader/
            └── Worlds/
                ├── YourWorld.wld
                └── YourWorld.twld

Steam Cloud Saves

If your world is stored on the Steam cloud, you need to temporarily move it off the cloud first:

1. Launch Terraria (tModLoader).
2. Go to the world selection menu.
3. Click the cloud icon next to your world to move it off the cloud. This will download a local copy of your save.
4. Re-enable Steam cloud after copying the files if desired.

4. Upload both your .wld and .twld files.
5. In the sidebar, navigate to Startup Parameters.
