Hi, I'm posting on behalf of my college mate, he recently defragge his laptop which had 32g free space.
After defragging he had only 28g however upon restarting his free space turned to 45gig?
Anyone know why this happend? I sent him to check all his files are there just in case right now.

I have no idea, but I do have a theory.
While defragging all the files are moved around and result is they are "loosened or fluffed up" a bit, so they take up more space. After a reboot, the disk stopping and then starting back up again will fling all the files to the edge of the disk, and pack them tight together, leaving more free space.
