How to Permanently Delete a World When You Don't Want It in the Trash

Understand what the mod changes

With this mod installed, pressing delete on a world no longer erases it. Instead the world folder is sent to your system trash so you can recover it later. That is the whole point, but it also means deleted worlds take up disk space in your trash until you empty it.

Empty the trash to reclaim space

If you are sure you never want a world back:

1. Delete the world from the Minecraft world selection screen as usual. It moves to your system trash.

2. Open your operating system's trash/recycle bin.

3. Locate the world folder and delete it from the trash, or empty the entire trash.

Once it is removed from the trash, the world is gone for good. There is no in-game step for this, because the mod deliberately hands the final decision to your operating system.

Skip the trash entirely

If you want a world gone immediately without a trash stop, delete its folder directly from your saves directory using your file manager instead of using the in-game delete button. Be aware this bypasses the mod's safety net, so there is no recovery afterward. Only do this when you are certain.
