  1. I am usually pretty content using the built in defragger, and use it on my storage drives (SSD as main OS drive, no defrag needed!). I have tried Defraggler in the past and loved it. But, I really don’t need anything beefy these days.

  2. Defrggler. Works well and the Piriform folks keep it updated

    Since Vista the build-in tool is enough. All other tools are useless.

    JkDefrag and it’s successors (MyDefrag) is a miracle for old or slow PC’s. It is my highest priority whenever I fix someone’s PC. Windows Defrag doesn’t “optimize” the disk and it doesn’t allow you to automatically clean temp folders before scheduled defrags. This is essential.

    I also disable Win7’s automatic defragmentation (through Task Scheduler) since it will ruin MyDefrag’s optimization and file sorting. This slows the disk down all over again and creates a lot more stress on the hard drive.

    I need to give Puran a shot though since it has MFT defrag.

    now there’s an idiot. LOL

    Puran wipes out restore point. Major flaw

    Mo discussion here …. the best defrag tool, bar none, is MyDefrag ( JKDfrag) … i have used and experimented with all that are mention and absolutely MyDefrag is the only one that has speed up my boot time ( faster boot) better performance and i get faster access to files and folders. Yes, these defrag tools are good and they all have many options and features and some are extremely fast defragging but NON, and i repeat, NOT ONE, lower my boot time when compared after performing a defrag with Windows 7 default defragger and then using any of the tools mention except MyDfrag. My boot time with Windows 7 defragger was 55 to 58 seconds on average and with the other tools the best i achieved was 44 seconds with Puran. MyDefrag gave me a boot time of 37 to 39 which is quite fast. It chopped of 18 to 19 seconds and that is why we all defrag our hard drives, to achieve maximum performance and better boot times. So i will stick with MyDefrag even though it is not beautiful and it is “slow” defragging and it really doesn’t have many options or features except that you can write your own scripts which is handy for power users and you can program scheduled defrags. Just give it a try and you will discover what i did…. MyDefrag does it’s job and period…….. no questions asked…. thanks J.C. Kessels for MyDefrag….

    All defrag tool will erase your restore points. This is an issue that has been debated for quite awhile. It has to do with the standard defragmentation API
    by Microsoft, a system library that is included in Windows OS and most consider that fault to be a bug. I personally don’t use Windows Restore since i perform image back-up of my OS and files and folders so i don’t worry about that.

  13. missismiggins

    Got to agree with you on that one. I have been using Mydefrag for years when it was known as JKdefrag, by far the best defragmenter there is and it is FREE! It knocks the pants off Microsofts offering (which I gave up on a long time ago in the early days of Win7)

  14. Bob

    Does MyDefrag wipe out the Windows Restore points?

  15. Victor Cristy

    I respect your opinion, have a question to ask you, in MYDefrag thers a note on their website that its best to restart windows in “Safe Mode” so as to get the most use of the program and can access more files that way? Is this another way that can be done using other defrag tools? What is your suggestion? Thank you

  16. Defragging in safe mode can give better results.

    Thank you Anand. 🙂

    The best of the best (free) : Auslogics Disk Degfrag, JKDefrag, Diskeeper, Defragler, UltraDefrag
    The best of the best (not free) : O&O Defrag

    If you can to have O&O Defrag so go go go because is the better in this domaine

  20. Software182

    Are you serious ?

    Diskeeper isn’t free !

  21. Heru Sutanto

    diskeeper is not free LOL

    Beware, Auslogics will tray-popup spam you, and give you an upsell page at every mouseclick. Even uninstalling forces you to take a survey, dodge a pop-up, visit an upsell webpage and CLOSE THE BROWSER before uninstall will complete. Not a good idea to trust your data to someone who uses tactics one notch below ransomware.

    Don’t install it under any circumstances, even curiosity. If they spent as much time making software as they did spamming, they’d really have something, but as it stands, their defrag is middling at best.

    If you just want a simple defrag, UltraDefrag is your best bet. Simple UI and comes in a portable version, so you don’t even have to install it.
