It's easy to come up with justification for why cleaning up unused hard disk files, from time to time, will help improve your computer's performance. Your PC's speed, during file accesses can be a function of the number of files and documents etc. stored there. This might seem odd, but it makes sense when you realize that you find that the file allocation system bloats and the drive system is subjected to more stress each time a file is accessed. Also keep in mind that file fragments get scattered around the hard drive over time and this cuts the speed that data can be retrieved. Additionally keeping private files private is more difficult, as you keep more and more private files on your computing system the greater the risk is that somebody else using your PC could put your personal data to their own malicious uses. And getting rid if these items that are no longer needed can return free space to the available data pool that may then be used for storing files you do need.

A growing number of cleaner tools can be found in so many different groups that look at the drive cleanup task from varying perspectives. Many free parental controls can be found just by checking on Google, using that keyword. This is not the only function that software can do, several of these can also get rid of old data from free space, detect and remove pornography, find programs that are not properly licensed, and show the distribution of data on your HDD.
