PSBruteZip allows you to brute force your way into Zip files should you have forgotten the password. A pre-req is that 7Zip is installed as it uses their commands. They function is better than Windows (I find).
Password protecting your files using a password is a great way to add additional security controls. The problem is, there are tools out there that can crack them. You may also be in a situation where you can't remember the password of a file.
