Unload a Dimension Without Losing Its Data

Removing Active Dimensions

When you no longer need a dimension active on your server, you can unload it safely. The saved chunk files remain on disk and can be reloaded later.

Steps

1. Open chat and type /dims remove_dimension <dimension>

2. Replace <dimension> with the ID of the world to unload (e.g., old_event_world)

3. Press Enter to execute

4. The dimension is immediately unloaded and removed from the world list

5. All connected players are synced to the updated world list

What Happens

• The dimension becomes inaccessible to players
• All chunk data, player structures, and world files are preserved on disk
• The dimension can be re-added later using add_dimension or clone_dimension without data loss
• No server restart is required

When to Use

• Temporarily disable a world for maintenance
• Reduce server load by unloading unused dimensions
• Archive a dimension while keeping its data safe for future use
