Thank you. Don't get me wrong. I love Defraggler as many people here but I think that it should be recoded from ground up. Also, I have always wondered why CC gets so many updates and Defraggler gets so few.
Another issue is that I get no feeling of novelty using Defraggler. You may not notice any great difference by running a one or two year old version. It's true, you cannot reinvent the wheel, but I think a little more polish is always welcome.
