Hello I want to save file in current world catalog and Im having problems how to get current world catalog. I tryed to use 

String worldName = event.getServer().func_240793_aU_().getWorldName();

But this only gives me world name not actual catalog and multiple worlds can have same name but different catalog. Any ideas how to get proper catalog?

Yes i mean directory. I know i almost always use capabilities when I can, but in this case I need it. I knew how to do it in versions before 1.16 but they change it.
