From Password Unlocker:
ZIP Password Unlocker is to recover forgotten or lost passwords for WinZIP/ZIP archives to open and extract the files and folders from the archive. Enhanced by three attack modes, this password recovery tool is dynamic in functions and quick in speed. The program is going to base on the dictionary you created to attack the password. The program attacks the password just via mutating these characters and character sets to try to match the guesses with the password, either randomly or reasonably.
