Publisher's Description
From Jeroen Kessels:
MyDefrag is a disk defragmenter and optimizer (a maintenance utility to make your harddisk faster) for Windows 2000, 2003, XP, Vista, 2008, and for X64. It is freeware, with no time limit, and is fully functional with no advertisements. It is fast, with low overhead and many optimization strategies. It can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. Included are a set of easy-to-use scripts for end users, a scripting engine for demanding users, a screen saver, and a combined Windows plus command-line version that can be scheduled by the Windows task scheduler or for use from administrator scripts.
MyDefrag 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.
What's new in this version: Version 4.3.1 adds the Windows "bootstat.dat" file to the build-in list of special exceptions.

"The best defragger for Windows (Vista) I've found."
Version: MyDefrag 4.3.1
Pros
It's fast.
It has a script language for the techies.
It comes with scripts already made for non techies.
It automatically schedules itself to run at 5am.
Disk map is very detailed, and you can zoom in and out.
It's free.Cons
I wish it wouldn't do just one run. If you stop it or it finishes defragging a disk, you can't then defrag another disk. You have to quit the application and then start it again.
There's no color key in the application.
The gui could be fancier.Summary
Get it. Install it. It's great. But as always, download only directly from the publisher because the CNet installer is (a) unnecessary, and (b) loaded with toolbars and other foolishness.

"Best defrag program PERIOD"
Version: MyDefrag 4.3.1
Pros
Fast
Automated
Basic stuff is simple
Fully customizable (via scripts) for advanced users
Scripts
More scriptsCons
It can't make coffee
It probably makes no difference if you have a solid state driveSummary
If you are looking for the best program to optimize your hdd performance then this is it. It runs completely off of scripts so you can use the ones it comes with or write your own. For those of us who play games that access the hard drive constantly (i.e. WoW), we can customize the scripts to put those files at the beginning of the drive so that they perform wonderfully, even on a full hard drive. There is documentation on the website so anyone who has done some light programming should feel right at home with writing scripts. This is an absolute must for power users.

"Simply the BEST Defrag Program out there"
Version: MyDefrag 4.3.1
Pros
Every other defrag program I've tried defrags the files OK, but leaves them scattered all over your hard drive. Therefore, while 25% of your drive may be "free space", it's contained in thousands of tiny little fragments of free space. This program not only defrags yours files, but gives you nearly unlimited options as to how to reorganize them on your hard drive so you have large, contiguous blocks of free space.
The hard drive map is VERY detailed (see the Con below). However, once you get used to it, it is fantastic to see exactly where your files are located and where the free space is on your hard drive.
You can move your cursor over any portion of your hard drive map, and it tells you the name of the file located in that portion of your hard drive and how many fragments it is divided into.Cons
The first time you open the GUI, it looks like abstract art. Unlike most defrag programs, it is showing you the status of each and every block and sector of your hard drive.
It would be nice if there were a color key on the screen to remind you what all the color patches mean on your hard drive. You have to go to Help to get this information.Summary
Download this one and forget the rest!

"Looks aren't everything"
Version: MyDefrag 4.3.1
Pros
Free. Fast. It seems to do a great job, and what's not to like.
Cons
Haven't found a way to start the program and have it shut down the computer automatically when complete.. but not a big deal.
Summary
This is a basic defrag program that doesn't have the pretty interface. It's almost like running DOS again. The screen looks old, but it's not about the appearance, it's about the job it does.. and it does it very well.

"Best defrag since Norton Speedisk"
Version: MyDefrag 4.3.1
Pros
The only free defrag I've found that will move start-up files to the front of the disk as well as this one, and sorts all files.
Cons
Interface but for free, who's complaining?

"Best disk defragmenter and optimizer out there IMHO"
Version: MyDefrag 4.3.1
Pros
Best defragmenter and optimizer program I have used.I was using this back when it was called JKdefrag.I tried others like Auslogics but this one is better in my opinion and does a better job.Auslogics left files scattered all over my hard drive and didn't optimize and line them up right.MyDefrag works like the old Norton Speed Disc use to but faster.With the other Free ones I didn't see as much speed difference as I do with this.Number one in my book.
Cons
There are non

Same as above.It may not be ranked number 1 but I think it is.Best defragmenter and optimizer program I have used.I was using this back when it was called JKdefrag.I tried others like Auslogics but this one is better in my opinion and does a better job.Works like the old Norton Speed Disc use to but faster.With the other Free ones I didn't see as much speed difference as I do with this.Number one in my book.

"WOW, great defrag program!"
Version: MyDefrag 4.3.1
Pros
This is a great defragger. It's my new everyday defrag program.
Cons
GUI is lacking but it works. Wish it had a boot option.
Summary
I can't count the number of computers that I've reformatted in the last ten years. I usually use the system defrag after all software and updates are installed. I've used other defraggers in the past but none seemed to be any better than the system defragger. Figured I'd try something new this time so I tried a couple other defraggers. First I tried Defraggler and UltraDefrag right after the install. I noticed no difference in speed at all just like the system defragger. Then I gave MyDefrag a try on the same fresh install and holy #$%! I cant believe the difference in app loading. All MSOffice programs load instantly on a p4 2.66. All other software loads quick as well. I really can't believe the difference from the other defraggers I ran on the same computer. I have several of the same p4 2.66's and none of them have ever been this responsive.

"Excellent Defragger"
Version: MyDefrag 4.3.1
Pros
I can actually notice a performance increase unlike Defraggler, and there is a wide variety of scripts to choose from for your every day needs including daily, weekly, and monthly. It's free to!
Cons
(Can) take a while to defrag, but its performance outweighs this by any level.

"For the bucks (free), very good software"
Version: MyDefrag 4.3.1
Pros
Easy to use, does work for all kind of volume, provide excellent and thorough de-fragging with noticeable speed improvement. Multi-level fragmentation schedule (daily, weekly, monthly) very good. Cannot get better with commercial products.
Cons
Old looking interface with mysterious color legend. Scheduling is not intuitive to me (how to schedule specific tasks toward one drive and other tasks toward other drives unclear).
Summary
You can replace the Windows defragger with MyDefrag with confidence that a good job will be done, this is one freeware which has kept improving over the years and concentrated efforts over working features rather than the interface and appearance - it shows and MyDefrag provides superior de-fragmentation coming at equal footage than what commercial products provides. NB: users have noted restore points issues; I do not use restore points (they often fail when needed the most so moved to other safer means) and this could may be an issue. Nonetheless, this product is an excellent choice if you are looking for a bit more than the basic Windows defrag features.
