Unloading an Active Dimension Without Deleting World Data

When a custom dimension is no longer needed in active rotation, DimLib Mod allows you to safely unload it from the server without risking any player builds or generated terrain.

Removing the Dimension

To unload a dimension from active memory, run the removal command:

/dims remove_dimension <dimension>

1. Replace <dimension> with the identifier of the world you wish to unload.

2. Press Enter to process the command.

Protecting Saved World Data

Unlike commands that wipe world folders, this command unloads the dimension while keeping all saved world files and chunk data safe on disk. The world is removed from the active dimension list and unloaded in real time, freeing up resources while the server remains online. If players on the server have the mod installed, their client dimension lists will update automatically to reflect that the world has been deactivated.
