Just downloaded it and took it through a test run, and it seems pretty nice to me. It's pretty quick and easy to use.
I do have one question though. When defragmenting a drive, does it do free space defragmentation as well? I see that there is an advance option to defrag the free space, but I was just wondering if I had to run them separate to achieve both. If I do have to run them separate to get both, could there possibly be an option implemented that allows defragmenting of the drive and free space at the same time?
