Can PDF Password Unlocker remove password from the PDF file which was zipped?

Question

There are 4 PDF files, which need password to open them, and then these four PDF files are zipped. The PDF files' password is forgotten, so, when I open the ZIP file, four PDF files appear, but I can not open them due to password protection.

Can these files be open through this software? Because in the trial version, when it asks the path for file to open, it will not accept ZIP file.

Answer 1

This application will only unlock the password for a PDF file, and not for the files inside a zipped archive that is password protected. For that you will need another application that is capable of bruteforcing the password because that's the only way you could gain access. There are those applications as well, but it's not guaranteed that will show the password, even with the bruteforce method.

You can use apps like Advanced ZIP Password Recovery for this procedure: http://advanced-zip-password-recovery.software.informer.com/
