Windows applications litter your hard drive with junk that serves no purpose. This junk can cause your PC to slow down and even cause some application problems. Many setup programs are prime examples of this. Other programs keep producing lots of unwanted log files. Yet others automatically create backup files of edited documents.
Internet browsers create a lot of cache files, 'cookie' files, history files, etc, etc.
The problem is that if you don't clean up such files periodically, your free disk space will slowly but steadily shrink and it will be more difficult to find the files that you do want because of all the junk littering it. If you are really unlucky, Windows may even crash because it hasn't got enough space for its virtual memory swap file. System Cleaner operates by regularly scanning your hard drive for various error producing files and then optionally cleaning them from your system for you. The error files that System Cleaner searches for and deletes can produce hazardous results if they are not properly cleaned from your drive on a periodic basis. System Cleaner 2001 is the ultimate tool for restoring hard-drive space , cleaning up the history of your activities on your computer and keeping your system running like new .
