i've just finished downloading a movie, but when i go to unzip it, it ask me for a password. is there anyone who can help me

You do realise that there's most likely a virus in the zip file ?, reputable downloads don't have passwords. Steer well clear.

In order to answer questions for other readers in the future, there's a product from passware that will allow you to open a password protected zip file. It's not free, but I think they still offer a free trial.

On a side note, I highly recommend the passware kit for anyone that supports IT. It's been extremely useful for password protected excel files, pdf files, etc... when users forget the password or an employee is terminated.

..however where movie downloads are concerned my previous post still stands; here's a very good reason to steer very clear - http://forums.afterdawn.com/thread_view.cfm/577223
