Uploading an existing world

Updated 4 Nov 2026

Find your world

On Windows, singleplayer worlds are in %appdata%\.minecraft\saves. Each folder is one world. Check it has a level.dat inside.

Move the nether and end

A server keeps them in separate folders. If you have been to the nether or end:

  1. Rename your world folder to world.
  2. Make a folder world_nether and move DIM-1 into it.
  3. Make a folder world_the_end and move DIM1 into it.

Zip it

Put the folders in a .zip. Not RAR or 7z.

Stop the server and upload

  1. Stop the server and wait for it to go grey.
  2. In the File Manager, delete the old world folders.
  3. Upload your zip, then choose Unarchive.
  4. Delete the zip.
Stop first

If the server is running, it will overwrite your upload when it stops.

Start and check

Start the server and join. Check your builds and go through a nether portal.

Problems

I spawned in a new world

The folder name must match level-name in server.properties, with level.dat directly inside.

The nether is new

It must be at world_nether/DIM-1. Move the DIM-1 folder itself, not what is inside it.

Failed to load world

Your world is from a newer Minecraft version. Raise the server version.
