First, I would like to thank the admin for your excellent product.
I have used since 1.01.044 and now use 1.01.073, the latest.
Up until 1.01.068, I had no trouble with "defrag Disk" feature.
In my understanding, it eliminates the gaps between fragmented files and defragments the files at the same time, making huge empty area at the end of the drive (bottom right area). I was totally satified with its function and its amazing speed compared with other similar products.
The latest version with introduction of "new Defrag algorithm", however, seems to do different thing to me.
When I "defrag disk" on certain drives, the results are total mess sometimes.
Defraggler tries to make the last area to "cache" temporary files, it seems.
The area becomes larger and larger on some drives, one of which turned into fragmented more than half of it in a worst case. I just wanted it to eliminate the gaps on some drives without any fragmentation after "defragment" using Defraggler. That was all.
With such numerous defragmentation on the way, I had to stop the function before it completed.
I guess such case happens when a drive contains number of large files. I can tell this, because on a 500GB drive which contains many movie-size files around 700MB or over, the problem mentioned happens. Whereas another drive of the same size with number of rather small files from a few MB to 1GB at most, mostly around some 10MB does not experience this problem. The speed of this feature has significantly reduced compared with other versions in every case.
I do not know if this problem appears in other versions since I deleted all the previous versions.
Maybe you could provide us those too.
Any suggestion on this issue would be appreciated.
