This application is able to: test and (or) Extract all zip files avaibles in one folder. Count the zip files and report if any is missing. A setup menu is avaible it automates the shellintegration. With Mass zip you can extract all those zips in One Click (ok maybe 2-3). I was using "Command Prompt Here" from microsoft, some little batches and pkunzip. I always wanted a graphical solution to this "problem" that's why I coded this little thing.
