Interesting.. I nvver thought of password protecting it.. However, are there any disadvantages such as corruptions? Or perhaps couold it be done to iso progs such as a game cd ?

Never had that happened to me.... (knocks on wood)

I think rar compresion is a lot harder to crack the password than zip,your better of multi raring all the stuff for the cd put a nice big pass on it ,say if if theres 20 parts keep the last couple onto another cd so if someone does crack the pass one day they will be still missing 2 parts
