For as long as I can remember, all the Defraggler versions I have used always had a very slow performance when defraggling small files. I cannot say what size they are but on my backup HD, when its defraging it, when it hits those small files, it takes 2-3 hours to do a full defrag. If I disregard those small files (guestimate), the same defrag would have taken less then 30 min.
Why is it so slow for small files?
