Washing an unclean computer that holds pornography picture files may be performed by many special purpose file scanning software products that are now available on the global internet. Many of these disk cleanup tools are created to detect and clean inappropriate content off of disks but also to speed up hard drive speed. Pornographic file analysis applications are specially meant to quickly remove history as well as clean up any of the unwanted pornographic material hidden in your home PC with ease. These programs are able to excel at statistical analysis, RealMedia format tests, drive cleaning and various other tests.

Image analysis must be accurate when using a program to check hard drive files , to clean out unwanted porn material. Pornography on the internet often takes the form of images, and in many circumstances the viewers of this content make a copy of the files on their PC's hard disk so they can be viewed again. It is important for porn cleanup tools to be aware of the differences between adult images and other images, and present the files in the most useful manner for the operator of the software to use. Sorting out the files usually involves processing to determine if porn is present. The first test is checking the contained skin colours in the image. However skin detection insn't the main factor because everyday images sometimes also contain skin color. Therefore if skin can be found, more advanced related tests are then used to further test the images, to isolate the porn images from normal ones, such as color pattern tests, color vector assesment, and many other factors. Images that are found during scanning are put in order and presented as thumbnails so they can be easily reviewed.
