Defraggler needs to defrag twice?

Hello everyone,
So another forum I am a member of said that Microsoft default maintenance tools like "disk cleanup" and "defrag" don't do the job very well and they were recommending "ccleaner" and "defraggler" I have already been using ccleaner to scan for registry issues but when I use defraggler I need to scan twice just to get the fragmentation down to 0%. Why is this and is there any real difference between defraggler and Windows defrag? Thanks for any input.

I have to scan twice sometimes.
Not every time.

Seems normal enough to me.

I like it better than Windows defragmenter making pass after pass after pass....

Thanks David Bailey, I was just making sure this was normal.

So I have ran the defraggler scan like four times and when I run the "analyze" option it is showing 17% fragmentation, I swear the scan I ran before was only 14 % Fragmentation. Is this because my drive is encrypted with Bitlocker? I am just saying I have never had to fun defraggler four times, any ideas?

The determination of fragmentation level is by no means an exact science. The numbers provided by different utilities will disagree significantly. I have never found them to be very meaningful.
