How to Reset Your Minecraft World

Resetting your world deletes all builds, player progress, and terrain, then generates a brand new world on next startup.

Before You Reset

Create a backup in case you change your mind. See How to Back Up Your Minecraft Server.

Steps to Reset

1. Stop your server from the control panel
2. Go to the File Manager tab
3. Locate the world/ folder
4. If you want to keep a copy, right-click and Rename it to world_backup instead of deleting
5. Delete the world/ folder
6. Also delete world_nether/ and world_the_end/ if they exist (Paper/Spigot servers store dimensions in separate folders)
7. Start the server — it generates a fresh world automatically

Changing the Seed

If you want the new world to use a specific seed:

1. Before starting the server, open server.properties in the file manager
2. Set level-seed= to your desired seed (e.g. level-seed=123456789)
3. Save the file, then start the server

Leave level-seed empty for a random seed.

Verify the seed after generation by running /seed in the console (requires OP).

Keeping the Same Settings

Resetting the world does not affect your server configuration. Your server.properties, plugins, mods, whitelist, and op list are all preserved — only the world data is removed.

Resetting a Single Dimension

To reset only the Nether or End without touching the overworld:

• Nether: Delete world_nether/ (Paper/Spigot) or world/DIM-1/ (Vanilla/Forge)
• End: Delete world_the_end/ (Paper/Spigot) or world/DIM1/ (Vanilla/Forge)

The deleted dimension regenerates on next startup.
