    Works very well. I like the improvements. It is probably the best of all for boot-time defragging. Maybe just a few more options about file placement, like recently modified, rarely used, and so on would be useful. And being able to find out what files were in a block would be useful at times. But technically, those things make no difference, anyway. It's just that many people like and use them. Good work and thank you. Try to ignore the negatives. It's pretty clear that most of them don't know how computers work, what is good and what is bad, and they have no business evaluating software for anyone.

    Could not uninstall; did not want the default C drive, but that's what the install program chose.
