How to switch between worlds on your Terraria server

Your server runs the world named in World Name, in Settings, Game Settings. Every world is a .wld file in saves/Worlds. To switch, set World Name to another world's file name without .wld, and restart. The other worlds stay on disk untouched.

See which worlds you have

1. Open your server in the panel and click the Files tab.
2. Open saves, then Worlds.
3. Each world is a file such as world.wld. The name before .wld is what goes in World Name. Files ending in .bak are the game's older copies of a world, not separate worlds.

Switch

1. Click the Settings tab, then Game Settings.
2. Set World Name to the world's file name without .wld, for example castle for castle.wld. Capitals count.
3. Restart the server. The Console shows the world loading, then the ready line.

If you type a name that has no file, the server creates a new world with that name instead. Check the spelling against the file name if you see a world being generated: Your Terraria server made a new world instead of loading yours.

Worlds and server types

All three server types keep their worlds in saves/Worlds, so a world made on Terraria Vanilla is still there after you switch to TShock or tModLoader. tModLoader runs an older Terraria and cannot open a world saved by Terraria 1.4.5: tModLoader cannot open your Terraria world.

Good to know

• On TShock and tModLoader, World Name cannot contain spaces. Rename the file in Files first if it has spaces.
• Only one world runs at a time.
