Uploading your local world to your Minecraft server

First of all, please ensure that your server runs the same modpack and version of Minecraft as your local world. Only Java Edition worlds can be uploaded. Bedrock worlds don't run on a Java server.

Step 1: Compress your world​

  1. Open the folder where your world is located. Singleplayer worlds are in the saves folder of your Minecraft folder (on Windows, %appdata%\.minecraft\saves), one folder per world.
  2. Open the world's folder. It usually contains data, DIM1, DIM-1, region and level.dat. Select all files with CTRL+A and right-click to see the menu. On Windows 11, select Compress to ZIP file.

Compress to ZIP archive

Otherwise, you will need to have installed 7-Zip which can be installed from here and use 7-Zip to add files to zip archive.

Step 2: Upload the world on the Worlds tab​

  1. Open the Fragnet dashboard, go to My servers and select your server.
  2. Select the Worlds tab. If you don't see it in the tab row, look under More.
  3. Select Upload world and choose your ZIP file.
  4. In the Upload a world window, check the World name. It becomes the folder name on the server. Use letters, numbers, - and _ only, up to 64 characters, and pick a name no other world on the server has.
  5. Select Upload world. A progress bar shows the upload.

The dashboard then unpacks the world. It's added as a new world; your current world doesn't change. When it's done, you see "The world is in place. Make it active to play on it."

info
  • The ZIP can be up to 4 GB. For a bigger world, upload the world folder with an SFTP client instead (see Other ways to upload a world).
  • The ZIP must contain the world's level.dat. It doesn't matter whether you zipped the world folder itself or the files inside it.

Step 3: Make the world active​

  1. In the list on the Worlds tab, select Make active next to your uploaded world.
  2. Restart the server, or start it if it's stopped (see Power controls). If everything was set up correctly (same version and same modpacks), the server loads your world.

Your previous world stays on the server. To switch back, select Make active next to it and restart. To remove a world you no longer need, select Delete next to it. You can't delete the active world.

The Worlds tab also lets you Download a world, and Reset one, which deletes it so the server makes a new world on the next start, with the same or a new seed.

Other ways to upload a world​

If you don't see the Worlds tab, or your world is larger than 4 GB, upload the world as a folder and point the server to it:

  1. Stop the server.
  2. Upload your world into a new folder in the server's main folder:
    • On the Files tab: select New folder and give it a name, for example myworld. Open the folder, Upload your ZIP into it and use Extract on the ZIP. Then delete the ZIP. See Files and SFTP.
    • Or with an SFTP client: upload your world folder into the main folder. See SFTP and FTP access.
  3. Make sure level.dat is directly inside the new folder, not in a folder below it.
  4. Select the Configuration tab, then server.properties. In the World group, set World folder to the name of the new folder, for example myworld. See Change a setting.
  5. Select Save and restart, or Save and start the server.
tip

Make a backup before you replace or delete a world. Deleted worlds can't be recovered without one.
