If you clean computer's Recycle Bin, the files and folders are not deleted forever. Anyone can use special recovery software and restore any deleted data (files and folders) because any deleted file still exists on the hard disk until will be overwritten with other data. The main purpose of this program is to make impossible recovery of files and folders which was deleted in the past. Program uses several security algorithms (DoD 5220.22, Gutmann and other). While working this program fills out information to the end of each cluster, leaving no chance to restore even just one word! Prevent Restore can wipe deleted files on any disk, for example: usb flash, SSD, memory stick or any other sort of removable disk (media storage). However you cannot use it on CD (CDR, DVD) - such disks you should physically burn to avoid any possibility of recovery. As an additional feature the program can erase paging file of OS Windows (virtual memory cache) which contains cache of personal information, for example: usernames and passwords.
