[Defraggler is useless i think. I have just uninstalled it.]

I though other programs were better than standard Windows 10 defrag tool. So I have given a chance to Defraggler.

My main drive is 1 TB WD10EZEX HDD. I don't have SSD right now.

First of all, volume shadow copy and other settings like that, increase defrag time too much. Okay, I have disabled them and defrag time improved but it is still much slower than Windows 10 Home standard defrag tool. Probably it defrags larger files too. 

I have tried fast defrag options and slow defrag problem was gone. But HDD performance reduced drastically either way. No matter what settings I have tried, I couldn't recover my HDD performance. The only solution is using standart defrag tool of Windows OS.

After Defraggler defrag --> Crystal mark calculated 90-100 MB sequential reading speed.

After Windows defrag -->  Crystal mark calculated >160 MB sequential reading speed.

Another problem is, moving larger files to the slowest section of the HDD. At first it is a good idea but unfortunately Windows started writing all new large files to the slowest section. Games and programs are loading slowly right now. I always move larger files with Windows standard defrag tool as a result. MEH. (Defragging empty space etc. didn't work for me.)

So, I have removed Defraggler and will not use any other defrag programs like this. Standard windows defrag is the best option because Microsoft knows best about their operating system, not third party developers right ?

- Make sure you regularly remove files from "Recent Files" (with e.g. Ccleaner), the file "layout.ini" in the "c:\windows\Prefetch" folder. Then this problem should be less of an issue.

- Check the size of the "Standby" part of the memory (Resource Monitor) before and after cleaning these files. It should be smaller. Or use Sysinternals' RAMMAP to check the memory usage. This program tells you what files are read and stored in the Standby part of the memory.

- You also use the option "Defrag Freespace" in Defraggler to move selective files to the beginning of the disk.

Thanks. I'll try.

- What kind of files are those who have been moved to the end of the drive ? Vidoes, pictures you opened/viewed recently ?

- I know that Windows keeps track of what files you have opened in the (recent) past. (e.g. "Recent files") These files are then read from the disk into the memory (with a low priority) in case you need them again. Then these files are much more rapidly available, from the memory instead from the (comparatively) slow HD. This mechanism uses a combination of things like "Recent files", "Prefetch" and the "Superfetch" Service.

- I could imagine that during the reading of those low priority files (that are placed at the end of the HD) the Operating system wants to write a number of files. Then these files are being placed at the end of the file because then the read/write head of the HD happens to be at the end of the HD. And then the firmware/OS decides to place those files at the end of the HD. Then the firmware/ Operating system doesn't want to wait for the read/write head of the HD to return to the beginning of the HD.

I have moved setup.exe etc. files to the end of the drive.

Nobody knows what to do for this problem. 

LOL.

- Makes perfect sense. Because Windows needs to keep track what has been changed (files, etc.) and put that in the (next) System Restore Point. All that info allows Windows to revert the changes that have been made when one installs a program or an app.

- Question: did the amount of free disk space shrink as a result of using Defraggler ? People have been complaining about that in the past.

Okay. Thanks for help. I'll consider this in the future when I defrag my disk.

Hello. I'm using WD Blue WD10EZEX HDD.

Disk usage is around 145 GB and it is a system disk right now.

I have moved some files to the slowest section with Defraggler which I use rarely.

After that I'm having a problem right now. When I download something, HDD writes some of the new files to the its slowest sections. (end of the disk) 

I think HDD, Windows or something see that slowest parts are used and writes some files to there.

So, I have defragged my disk with Defraggler without moving large files to slowest section for a solution.

Today, Steam updated CS:GO and... my disk used its slowest section for some new files again.

How can I solve this problem? I didn't have any problems like this before Defraggler afair. Thanks!

Seems like no problems so far.

Hi!
I'm defragging my 1 TB HDD with Defraggler.

It is slow. I tried these steps together at first for speed-up:
Disabling volume shadow thing for NTFS.

Disabling benchmark after defragging

Excluding pagefile, hiberfil etc. files.
Excluding moving big files to the end of drive

All of these have improved defrag speed but it was still slow. 

Then today I tried something else: Closing system restore tool of Windows 10.
Now it is much much faster. 

So here is the question: Is disabling system restore points of Windows 10 for defragging, right thing to do ?
