Move an existing world to your WinterNode server. Use SFTP: it handles worlds of any size, where the File Manager caps out at 100MB. Bringing an existing world over is a common first step when you move to Minecraft server hosting with WinterNode.

Upload with SFTP

  1. On your PC, find your world folder. It must contain a region folder and level.dat directly inside it, not in sub-folders. Optionally compress it into a .zip to speed up the transfer.
  2. Connect to your server with an SFTP client.
  3. Drag the world folder (or the zip) into the remote side of your client.
  4. If you uploaded a zip, open File Manager, click the kebab menu next to it, select Decompress, then delete the zip.
  5. Continue to Set the world name.

Getting your world files

  • Aternos: log in, go to Files, open your world folder, and click Download.
  • Another host: look for a Files or FTP section in its panel.
  • Singleplayer: your worlds are in %appdata%\.minecraft\saves\ on Windows.

Set the world name

  1. Open File Manager and edit server.properties.
  2. Set level-name to the exact name of your world folder.
  3. Save, then start your server.

The server looks for a folder named world by default. Spigot-based servers also create world_nether and world_the_end.

Moving a world between Vanilla and Spigot? The format has to be converted first. See Spigot & Vanilla World Formats.

Frequently Asked Questions

Log into your Aternos panel, go to Files, open your world folder, and click Download. You'll receive a zip file you can upload directly to WinterNode.

At minimum, your world folder must contain a region folder and a level.dat file. Additional files vary by game version and server software.

If your world folder has a name other than 'world', update the level-name property in server.properties to match.
