It's not hard to think up reasons why cleaning up unused computer files, especially those you no longer need, can provide several tangible benefits. The speed of your hard drive subsystem when reading files from the hard drive or other storage system can vary depending on how many and how large the files are stored there. This occurs because you find that the file allocation system bloats and the system has to do more work whenever it is asked to retrieve a file. Another side effect of saving and deleting files is that these files get broken up (fragmented) and this increases when there are more files on the drive. Additionally keeping private files private is more difficult, when you have a large number of your personal data files, there is the possibility (no matter how remote) that other persons using your system could find and misuse these files. And getting rid if these items that are no longer needed can return free space to the available data pool and this might stave off having to buy a bigger hard drive.

An incredible variety of disk cleaning software utilities exist. One of these addresses the problem of detecting and removing pornographic material. A good example is Snitch software by Hyperdyne Software. It has been designed to use state of the art technology to accurate detection of inappropritate material. Also remember that there is much more that other cleaning software can do, many can also clean up orphaned data, clean up porn files, detect pirated software, and help you find where all the space has gone on your drive.

It is not difficult to gain drive speed back just by getting rid of unnecessary files on your PC with software like Snitch. The computer can run faster if there are less files to be handled, stored and managed by the drive. Any spare space that is recovered after cleanup is complete will naturally offer performance improvements due to reduced clutter. And when doing a defrag the outcome is improved when the hard drive is not cluttered with many useless files. And with the temptation of private files taken away, it is then unlikely that they can be misused by anybody that is not authorized to view them.
