Manual World Seeds and World Resets


Manual World Seeds and World Resets

When launching a new multiplayer adventure, you may want to generate terrain with a specific seed from Minecraft forums or seed generation tools.

Important Concept: Changing level-seed in server.properties will only impact newly generated chunks. Existing chunks already saved to disk will remain untouched. To apply a new seed across your entire world from spawn, you must reset or rename your world folder.


Setting a Custom World Seed

Step 1: Stop Your Server

In the dashboard console, click Stop and wait until the status shows offline. Never alter configuration files while the server process is actively writing chunk data.

Step 2: Edit server.properties

  1. Navigate to Files in your dashboard.
  2. Click on server.properties to open the file editor.
  3. Locate the setting:
level-seed=
  1. Enter your custom seed (numeric or text string):
level-seed=-74289374982374
  1. Click Save Content.

Step 3: Delete or Rename Existing World Folders

In the File Manager, locate your world directories:
  • world (Overworld)
  • world_nether (Nether dimension)
  • world_the_end (End dimension)

Select these folders and click Delete (or rename to world_backup if you wish to archive past structures).

Step 4: Boot Your Server

Return to the Console and click Start. The server will notice the absence of world files and generate brand-new terrain using your designated seed value.

Uploading a Singleplayer World

If you have already built a world in singleplayer and want to transfer it to FreeMcHosting:

  1. Press Windows + R, type %appdata%\.minecraft\saves, and find your world directory.
  2. Compress the folder into a .zip archive.
  3. In the FreeMcHosting File Manager, delete or rename the current world folder.
  4. Upload your zip file and use the Unarchive option to extract it. Ensure the folder is named world (or update level-name in server.properties to match your extracted folder name).
  5. Start your server.
