Does Defraggler Work?

I just ran version 1.02.078 on my system. After it had completed it told me that I still had one fragmented file. I then clicked Analyze' and was told I had 35 fragmented files! So, I ran it again. It took pretty much the same amount of time to run as the first time. It gave me the same results. Once again I clicked 'Analyze' and this time I was told I had 40 fragmented files. I ran Defraggler a total of five times. The esulting statistics were always the same; the following analysis kept on changing. Finally I returned to Windows' Defragmenter. It recommended that I defragment my hard disk. I did so, using Windows' Defragmenter. The program ran for some time. I then had Windows' Defragmenter analyze my hard drive. Its analysis agreed with its results.
