I have just downloaded and tried Defragler 2.00.221 BETA,
It is impressive software and works with no bugs (yet) on my old Dell XP.
Here are a couple of suggestions:
1. A pause option would be useful on the Boot-time defrag so that the user has a chance to see what has been done.
2. It would be nice to know what order (if any) defragmented files are place in for each option. Just a few paragraphs under "Help" would do it.
