How to Reset Your Minecraft Server World

Resetting deletes the world folders so the server generates a new map on boot. Plugins and configs aren't touched. Back up first, deleted folders can't be recovered.

Fact

Deleting /world, /world_nether, and /world_the_end doesn't touch plugins or permissions, those live in separate folders.

Fact

You can reset just the Nether or just the End by deleting only that one folder, the overworld stays untouched.

Before you start

Back up before touching anything. This is not optional, deleted world folders are not recoverable.
Server needs to be stopped before deleting world folders.

Steps

Back up first

1Backups tab.
2Create a new backup.
3Wait for it to finish before continuing.

Delete the world

1Stop the server from Console.
2Go to Files.
3Delete these folders:
world, world_nether, world_the_end
4Start the server. Fresh folders generate automatically on boot.

Change the seed (optional)

1Files → open server.properties.
2Edit level-seed=.
3Leave blank for a random seed, or enter a specific one.
4Save, then start the server.

Reset only the Nether or End

Delete only the matching folder instead of all three.

Nether only: delete world_nether.
End only: delete world_the_end.

The overworld and everything else stays untouched.

What stays intact

Plugins, configs, and permissions live outside the world folders and are not affected. Only world, world_nether, and world_the_end hold map data.

Verify

Start the server and check Console for world generation lines on boot. Join and confirm spawn looks new, not your old base.

If it doesn't work

Old world loads anyway. A folder was missed, check for a renamed or custom world name in server.properties under level-name.
Plugins broke after reset. Some plugins store per world data inside the world folder itself, check that plugin's own backup or config before deleting.
Need the old world back. Restore from the backup you took in step one.
