I wanna ask about the Postgraduate diploma (which is obtained when you pass all master-degree courses but without doing the thesis), are there universities that allow this diploma holder to just do his thesis and after passing the thesis defense step will they grant him the master degree? or he should start new master (courses+thesis)??
It might not be accepted by the other University even other departments in the same University but you can request for credit exception when you register for their master program.
However PG Dip is direct advantage when you applying for higher research degree program such MPhill, PhD.
