If you are going to open each module at least once in your lifetime, it makes sense to do it only once by importing them into a (say) ADA bathrooms.PLN, arranging them into a neat grid with their names or whatever, and then store that PLN in that folder.
When you need to use bathrooms modules you open that file in a second copy of ArchiCAD, quickly find what you are after, and copy-paste them into your module (Suspend Groups unchecked).
