Hey all. The 1st time I ran defraggler it done wonders and recently I gave it a shot again and it went from like 80 billion bytes or whatever to like 89 billion, so the used space is going up? I thought its job was to give the computer more space... its not just this laptop, its happened on one of my other laptops and on my friends laptop, I don't know if this is a problem with the program or my computer but can you help me out here?
