This one’s easier than the defrag article I posted a while ago. I mean if you’re not much into computers, it’s the easiest thing to do. For an easy hard disk cleaning, you can just empty your Recycle or Trash bin regularly. The files or programs that you think you’ve deleted can come back and hunt you since they’re still in the Trash bin. And yes, they’re still taking up space in your hard drive. Another thing you can do is to clean the temporary files that your system keeps for a little documentation.
