if u look at the newly posted screenshots of pid v5.1 on my site u will see a window called 'CD/DVD util'.
it exactly does what u requested
íīve uploaded a new screenshot showing the 'Protection Report' window after doing a Folder Scan. quite simple now, just click folder scan and choose your game directory. all files will be checked (thout itīs fast) and only protected files will be shown in the 'Protection Report' window.
