Thanks - I thought it was fantastic too - it has saved me so much time!
And Julie, sorry, no I don't know how it handles passwords, other than if one is needed, it might stop at that file and give a code. I always double check my files after the job is done - to make sure everything unzipped ok.
If I find any 'empty' folders - I try to unzip that file again - sometimes it didn't unzip right because it was corrupt or a password was needed - which I then enter. If a file is password protected - you have to have the password - there isn't any program that will allow you to unzip a file that is password protected - without the password. That is done to ensure against piracy.
So - if the program doesn't prompt you for a password during the unzipping, then check the folders afterwwards to find the ones that are empty - then re-check their zipped version. Maybe the web site where we downloaded it from would have information on it. That's all I know for now.
