How to Upload a Minecraft World to a Server

Have a world from singleplayer or a downloaded map? You can upload it to your Redfox Cloud server via FTP in about 10 minutes.

What you need before you start

  • An active Minecraft server on Redfox Cloud.
  • An FTP client: WinSCP (Windows) or FileZilla (Windows, macOS, Linux).
  • The world folder on your computer. It must contain the level.dat file.
Make a backup

Uploading a new world deletes the server’s current world. If you still need it, download it to your computer first.

Uploading the world

  1. Find the world on your computer

    Singleplayer worlds are stored in the saves folder. Choose your operating system:

    Press Win + R, paste the path and press Enter:

    %appdata%\.minecraft\saves

    Each folder here is a separate world. If you downloaded the map from the internet, extract it first.

  2. Rename the world folder to “world”

    The server only loads a folder with a specific name. Copy your world folder, for example to your desktop, and rename the copy to:

    world
    Common mistake

    The level.dat file must be directly inside the world folder, not in another folder inside it, e.g. world/My world/level.dat. This often happens after extracting a downloaded map.

  3. Stop the Minecraft server

    Stop the server in the Redfox Cloud control panel. A running server saves its own world when it shuts down and will overwrite the files you uploaded.

  4. Connect to the server via FTP

    You’ll find the login details in the service control panel, in the “FTP/MYSQL/RCON” section.

    Here you’ll find the server address, username and password.
    1. In the File protocol field, change SFTP to FTP.
    2. Make sure Port number is 21.
    3. Host name: the server’s hostname, e.g. g01.rfox.cloud.
    4. Enter the username and password, then click Login.

  5. Delete the old world on the server

    In the root directory, open the pasauliai folder. It contains three maps:

    pasauliai/ ├── world main world ├── world_nether Nether └── world_the_end End

    Delete the world folder. Leave the Nether and End folders alone unless you’re replacing them too.

  6. Upload your world

    Drag your world folder from your computer into the server’s pasauliai folder in the FTP client. After uploading, the structure should look like this:

    pasauliai/ └── world/ ├── level.dat ├── region/ └── ...
    Tip

    Large worlds take a while to upload. Don’t close the FTP client until all files have finished uploading. An incomplete upload is the most common cause of a corrupted world.

  7. Start the server

    Go back to the Redfox Cloud control panel and start the server.

Did it work?

Join the server in the game. You should spawn in your uploaded world, near its buildings. If you see a completely new world, check the common problems below.

Common problems

The server generated a new world instead of mine

There are usually three causes: the folder isn’t named exactly world (in lowercase), level.dat is inside a nested folder, or the server was still running during the upload. Stop the server, delete the newly generated world folder and upload again.

The main world works, but the Nether and End are new

In singleplayer, the Nether and End are stored inside the world folder itself (DIM-1 and DIM1), while the server keeps them in separate folders. Stop the server and move DIM-1 into world_nether and DIM1 into world_the_end, replacing the folders with the same name there.

The world uploaded, but blocks are missing or the server won’t start

Check that the world was created in the same or an older Minecraft version than your server. An older server can’t open a world created in a newer version. Also check that all files were uploaded.

Can I upload a Bedrock Edition world?

Not directly. Bedrock and Java worlds use different formats, so this tutorial only applies to Java Edition worlds.
