Top 5 Free Defragmentation Software for Windows 8 / 7

Microsoft has substantially improved the native Defragmenting Utility in Windows, with the release of Windows Vista, and further improved upon it in Windows 8 | 7 and Windows 8. The defrag engine and the manageability of fragmentation is much better than what existed in Windows XP.

The in-built Disk Defragmenter in Windows 8 now runs as a low priority task in the background without affecting the performance of the computer. It uses the Task Scheduler to automatically keep the hard disk defragmented, by running when the machine is idle, and therefore does not affect the performance of the Windows. Windows 7 will disable disk defragmentation on SSD system drives, as you do not need to defrag a Solid State Drive.

The Windows Defragmenter, defragments files which are smaller than 64 MB only, for according to Microsoft’s benchmarks, fragments of this size, which already consist of at least 16000 contiguous clusters, have a negligible impact on performance. This means that games and large media files are effectively left as they are ! Microsoft feels that to defrag to combine fragments that are 64MB or larger requires significant amounts of disk I/O, which is against the principle of minimizing I/O, and puts more pressure on the system to find large, contiguous blocks of free space.

If you still want to defrag files larger than 64 MB too, you need to use certain other defrag parameters to be able to defragment files of all sizes.

For most, the best practices for using defragmentation in Windows 7 / 8 are simple – you do not need to do anything. But if you feel that you need to have a 3rd party defrag tools to better defrag and/or even defrag very large files easily and quickly, or if in spite of doing your best to troubleshoot the in-built disk defrag utility, you are unable to get the in-built defrag tool working, you might want to check out these 5 free defragmenting software.

    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.

    Defrggler. Works well and the Piriform folks keep it updated

  • André Ziegler

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

    JKDefrag was a really good software . I was looking for new version of it and thanks for your help . I should check MyDefrag . it must be good . Thanks .

    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

    I think WinContig is specially defragment stand-alone file or folder! appnee.com/wincontig/

    Puran wipes out restore point. Major flaw

  • George Melendez Correa

    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.

  • 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)

    Does MyDefrag wipe out the Windows Restore points?
