Create an Additional World

Each Minecraft server allows you to create additional worlds. You can create additional worlds to separate your creations or for troubleshooting purposes. This article only deals with creating additional worlds, and not running them on your server at the same time. To run multiple worlds at the same time, install CraftBukkit and a multiple world plugin like Multiverse or MultiWorld.

A Minecraft server stores each world in a separate folder. Each folder includes level.dat, which contains the world seed and other parameters, and a folder that contains region files. Region files store what you have built and the state of various in-game things. Depending on how a server is setup, the folder may contain additional folders that contain the dimensions of the world. The layout of each dimension folder is similar to that of the main world.

Create an Additional World

1. Login to Command Center.
2. From the server list, choose the server that you would like to modify and click Manage.
3. Go to Files.
4. Open server.properties.
5. Find the line containing level-name=[world name] and note whatever is after the = sign. On most servers, it is world.
6. Change level-name=[world name] to something different than what’s there. For example, level-name=world-1.
7. Save the file and restart your server.

When your server restarts, it’ll generate the world in a folder with the same name as the level-name you chose. On our system, the level-name is case-sensitive. For example world is different from World, and will result in two different world folders on your server.
