Deleting a hard drive which has pornography picture files can be assisted with the help of one of many custom designed detection utilities that are now sourceable on the software vendors' websites. Every one of these hard disk cleanup software products are designed to cleanup offensive material from hard drives and help improve system speed. Adult file detecting utilities are created to quickly clean disk and purge unwanted pornographic files on your hard disks without fuss. These programs (with few exceptions) include scans like image detection, video review, file washing and various other tests.

Detection of images must always be done when scanning your file system , to find any adult material. Online porn often takes the form of images, and some times the collectors of said material will keep a collection on the computer so they are within reach. Therefore it is a key task for porn detector tools to be able to separate good ones and bad ones, and display these files in the most meaningful way for the operator of the software to review. Isolating the files will involve processing of the files to find out if pornographic content is found. The first objective is finding levels of skin colours in the image However skin detection doesn't necessarily mean porn since sunsets and portraits exhibit tones similar to skin. Therefore if skin is in fact present, further followup tests can be employed to test them in detail, to bring apart the adult images from everyday images; including color evaluation, content testing, and various other types. Images that are found during scanning are grouped and shown as thumbs for the operator's inspection.
