Top 8 Best Windows Defrag Alternatives


One of the low points of using Windows as your operating system of choice is that you have to defrag its file system once in a while to keep it running at an optimal level. This is because of the way Windows stores and delete files which makes your data scattered all over the hard disk, thus making the process of finding it later becomes slower over time.

To makes matter much worse, the default Windows defragmenter is not that efficient but thankfully, there are many free Windows file defragmenter applications out there that does a better job.

Here are 8 of the coolest, free windows disk defragmenter alternatives:

  1. After evaluating some of the freeware and commercial defraggers, my preference for a hassle free efficient defrag is Diskeeper. The full version has some advanced features like the auto option that are really useful.

  2. The best defragmenter, in my experience, is Diskeeper 2008 Professional. It has features such as MFT defrag, page file defrag, fully automatic defrag (also manual or scheduled), simultaneous multiple drive defrag, an excellent GUI, VSS compatible defrag (for Vista) etc. etc. None of the freeware defragmenters in the list have all these useful features. All I had to do with Diskeeper was install it and switch on the automatic defrag, it did the rest. The only downside is that Diskeeper is not freeware, but then again, i guess you get what you pay for.

  3. I use Diskeeper in my desktop PC and OO Defrag on my laptop. After defrag my external hard disk using OO Defrag, the drive working more faster. When I click open the drive, it displays instantly. Not sure about Diskeeper because I always set it to run at background. Probably it is good or maybe not.

  4. in my opinion i think the best software for defragmenting your drives is ultimate defrag free version.It defrags everything and ur pc running a lot much more faster than ever….

  5. Most of these use the same Windows Defrag API that the built-in defrag uses, so all you’re getting is a different interface into the same functionality. From the JKDefrag page: “JkDefrag is based on the standard defragmentation API by Microsoft, a system library that is included in Windows 2000, 2003, XP, Vista, and 2008. Most defragmenters are based on this API, including the free defragmenter that comes with Windows and many commercial defragmenters.”

  6. I use Diskeeper Pro premier 2009 It is the Best defragmenter Ever been made .. I know this version is very very very costly but it is worth buying.. it has unlimtied hightech features and very smart defraging engine so my choice is This!!!!!!!
