How do you separate folios in the same layout so that you have one folio per room?

By saving under and deleting folios that have nothing to do with the piece...

If I understood the question correctly, there are different parts in a single plan? each room being in a different folio?

As @ac-cobra says, you can "save as" the drawing in as many times as there are parts (and put the name of each part in question). Then delete all unnecessary folios with each drawing

Or by copying and pasting folios into a new drawing
