I love and trust Pirifrom's CCleaner so much it's my fav. tool but it surprises me that such a good developer releases this Defraggler... on many occasions, I tried it, and got the same results, but everytime they release a new version. I feel like giving it the benefit of the doubt....no luck... I have a 1 TB HDD along with my SSDs (which I don't defrag obviosly) So I click on the HDD and hit defrag, estimated time to finish is 9.5 hours for god's sake! and I'm wondering, what on earth is it doing? Even PerfectDisk although uses a more advanced method of defargmentation called SmartPlacement which places the most used files on the outer edge of the disk for faster access, still beats defraggler by a foot's pole So after I was intimidated by that 9.5 hour ETA, I quickly closed it and ran the Windows built in Defragmenter it finished the job within 10 mins! surprisin' me... heh
I always use the Auslogics Registry Defrag that are in the Boost Speed application and it work fast. It's free!
