Thank you Michael, yes i ahve understood that myself yesterday after one of the guys here have shown the output of os.walk(path) in IDLE. 
So, yes in fact i was in need for the 3rd item in the tuple, so to get hold on to the files.

Thank you for supporting me, some ppl here think i'am a troll and don't try thinks or ignore evrything but 'some_ppl's_opinion != True'

I'am just sometimes persistant on having thing my way that why i was calling my self Ferrous cRanus, which i changes it since it was annoying....
