    thanks for the list of defrag program for my Win10 system but I also have an WinXP and Linux computers. What about those?

    Defragmentation for Linux is a heresy, be careful, Linux fanboys might overreact if you ask them about it. 😉 Win XP had a decent graphical built in tool to do the same. I remember the old Auslogic 4.5 was good.

      Hi Alex, Thank you for your comment. We agree with you, Windows XP had a pretty graphical inbuilt tool for defragmentation. Also, it exists in the existing Windows version too. But using a defrag tool makes the task easier, accurate and can be done faster.

    I am not sure about Defraggler and SmartDefrag and the other software but Auslogics Disc Defragmenter is flagged by Malwarebytes AntiMalware for containing malware (it even flags its “.exe” installation-file). Plus the most-recent version of Auslogics Disc Defragmenter doesn’t-include “Defrag & Optimize” as an accessible option in the free (“free” as-in “$0.00”) version anymore. Every time you try to use it a popup appears asking you to change to the paid version ([which Auslogics have called] the “Pro” version). I’ve been using Auslogics Disc Defragmenter back in the Windows-XP days when CNet.com & Download.com & OldVersion.com didn’t have a-whole-bunch-of-malware bundled[-]in to every downloadable file they have. & turning Auslogics Disc Defragmenter into “pay to unlock the features that used to be in the gratis version” have been a real downer. Please update your article to reflect what I said (that “Defrag & Optimize” is now only-available in the paid version, and that Malwarebytes AntiMalware flags the “.exe” file as containing malware).

    ” Elaine I am not sure about Defraggler and SmartDefrag and the other software but Auslogics Disc Defragmenter is flagged by Malwarebytes AntiMalware for containing malware …” exactly. another program that went straight to quarantine is auslogic’s duplicate finder. i immediately deleted it (along with everything bluestacks) another thing i don’t like about auslogic’s defragmenter is the use of 8 point fonts. please provide a gui that i can read

    You missed PerfectDisk Pro, which can change the defragmentation algorithms depending on the type of disk – HDD, SSD, or virtual. PerfectDisk can also defrag those pesky system files such as pagefile.sys and swapfile.sys that cannot be defragged while the system is operating.
