Hello Fernando,

Not a great solution, but at least something to consider if you have processing time to throw at it. Since the winzip can be command line driven, you can write a program in VFP (or something else) which gererates all possible passwords, EX a b c d....aa ab ac... etc using a couple loops. Then embed these passwords one by one into a command string and execute. You will probally have to let this run a couple of days/weeks/months depending on how long the password is and how fast your computer, but should only take a few minutes of your time to write the program.

Like I said it's not a great solution, but one I have actually used sucessfully! Mine took 3 days to find the right password, good luck

When I tried to unzip the files winzip asked for a password. As I didn't have the password I asked my client's people what was the password. They didn't know it (even that the file was password protected)! We tried some "possible" or "usual" passwords but it didn't work.

We told him about the problem, but he didn't remember the password. He suggested us us to "try" some other "possible" passwords, but...
