Even a quick look on the internet reveals a massive collection of software tools that work the drive cleaning process from varying perspectives. A good range of pc cleaner tools are now available that are able to detect and remove unwanted material without user intervention. But this is not all these products are capable of, several of these can also do free space cleaning, clean up porn files, find unlicensed software installed on the computer, and help you find where all the space has gone on your drive.

One can significantly improve system performance by taking a little time to clean up your computer's drive. Your computer can perform better, regardless of computer type, if there are less files to be handled, stored and otherwise handled by the drive storage system. The additional space that is freed up after cleanup is complete can only be of benefit by making space available for more important data. And defragmentation is more effective when the system has lots of free space to shuffle files around in. Also with all unneeded private files backed up and cleaned up there is less chance that they be seen by untrusted parties.
