How to reset the world on your Minecraft server

Resetting means deleting the world folder so the server generates a new one on the next start. Nothing else changes: plugins, mods, settings and players’ operator status stay.

Reset it

1. Stop the server.
2. Backups: take a backup if you might want the old world back. Restoring it later takes one click.
3. Open Files and delete the world folders. On Paper, Purpur and Spigot there are three: world, world_nether and world_the_end. On vanilla, Fabric, Forge and NeoForge the nether and end are inside world, so deleting world is enough. Modded servers can have extra dimension folders inside world too.
4. For a specific world, set World seed and World type in Settings, Server before starting. Leave the seed empty for a random world.
5. Start. The new world generates on the first boot, which takes longer than usual.

Reset only one dimension

Delete just world_nether or world_the_end (or world/DIM-1 and world/DIM1 on vanilla and modded). The overworld stays; the nether regenerates with its current seed.

Player data

Inventories and positions live in world/playerdata; deleting the world clears them. To keep inventories, copy world/playerdata out first and back in after the first boot (the same UUIDs still apply).

Good to know

• A hibernating server counts as stopped; you can still stop it explicitly before editing files.
• Big worlds take a moment to delete; the file manager shows progress.
• For a downloaded map instead of a generated one, Resources, Worlds installs it, or see Upload a world.
