andym carpal tunnel Registered: 17/01/2002 Posts: 3995 Loc: Manchester UK	Someone at work has archived a load of stuff into a password-protected zip file. They now can't remember the password. Any pointers to something that could brute-force the p/w overnight? _________________________ Cheers, Andy M

Googling "zip crack" returns a lot of results. AZPR seems likely. Edited by wfaulk (19/10/2007 17:00) _________________________ Bitt Faulk
