You never know what you will learn on Facebook! My friend Joe was upset that he lost 20 gigs of memory after defragging his computer and could not find it!

Now, you know that having pc problems is like going to bed angry. There is no sleep until it is resolved. What better way than to post for help on Facebook? And help Joe got.

It's pretty "techie", but here's the basic reason it happened: that restore feature available in case you need to fix your computer and restore the info from a certain time takes the stuff you defrag and copies it.

There are many things computers do that I don't understand. I'm sure you don't really understand this stuff either. That's why IT guys exist! Here's the fix from one of them. And now you know.

God bless the IT guys!
