How do I reset or delete the world and generate a new one?

Starting fresh is easy: delete the world folders and let Minecraft generate a new one on the next boot. Because this permanently removes your current world, it's worth backing up first if there's any chance you'll want it back.

How a world reset works

Minecraft stores each dimension in its own folder — world, world_nether, and world_the_end. Delete them and the server simply generates brand-new terrain on startup. You can optionally set a new seed at the same time.

Step-by-step

1. Stop the server.
2. In Files, delete the world, world_nether, and world_the_end folders (or rename them if you want to keep the old world).
3. Optionally set a new seed in server.properties (level-seed=).
4. Start — Minecraft generates a fresh world.

Warning: This permanently removes the old world and everything in it — builds, player positions, and inventories. Back it up first (Back up now on the Backups page, or download via Files or SFTP) if there's any chance you'll want it back.

Frequently asked questions

Can I keep the old world just in case? Yes — instead of deleting, rename the folders (for example, world to world_old). The server makes fresh ones and your old world stays on disk.

Will this reset player inventories? Yes — inventories live in the world's playerdata, so a full reset clears them and everyone starts fresh.

How do I set a specific seed for the new world? Set level-seed=YOURSEED in server.properties before the first boot after deleting the world. Leave it blank for a random seed.
