How to Defrag Your Hard Disk in Windows Using Defraggler for Performance

When a file is written to the system, it is spread across the hard drive. When the file fragments are all over the disk drive, it might slow down the system. So, it is essential to use defragmentation software to clean-up the fragments on an on-going basis.

Defraggler is one of the best free defragmentation software. It is very easy to use, and loaded with several useful functionality. This supports both NTFS and FAT32 file system types.

1. Display Hard Drive Health Info

This can give some high-level information about the drives used in your system. For example: Serial Number, Interface, Transfer Model, Buffer Size, Rotation Speed, etc.

Also, it can give several drive attribute’s current value. For example: Read error rate, spin-up time, start/stop count,seek error rate, temperature, etc.

3. Search Files

You can perform search based on several criteria. For example, files greater than a certain size. For every result, it will display the filename, number of frangements, size, type and full-patch.

Instead of running the defrag manually, you can schedule it to execute on an on-going basis. In the following example, it does a defarg every week on Sunday.

    Very detailed review of Defraggler. I personally have Defraggler but i do not use it to defrag my HD but to use some of it’s features like benchmark tool, search files, display disk block info, display hard drive health info and I will tell you why. Yes, Defraggler has a ton of options and features but what good are they if you don’t experience a performance advantage??? It does defrag you HD & there is some performance gain but let me explain what I mean. I have used, in the past years, just about every defragger on the market (IObit, Auslogics, O&O Defrag, Puran, DiskTrix, Disk Perfect, Disk Keeper, Ultra Defrag) and when compared to the Windows 7 defrag there is, in some cases, a performance gain but not much. I am looking for better boot-time, faster file access and better performance. You are right in pointing out all the options & features that Defraggler has and how fast in defrags your hard drive but I am interested in better boot-time, faster file access and better performance and that is why use MyDefrag. MyDefrag is a little slow defragging and doesn’t have all the options & features that Defraggler has so that’s were Defraggler comes in & I use those features like I mentioned before. Don’t get me wrong, all the mentioned defrag tools, including Defraggler are good at what they do but MyDefrag does it better. Boot-time with Windows 7 defrag is 51 seconds and with MyDefrag is 34 seconds. The second best time is with Puran with a boot-time of 43 seconds. So that is my experience with defraggers and I will stick with MyDefrag until another tool shows up. Do the experiment yourself. Thanks for such a good review and hope to hear from you…
