Because I am running an older machine with 6 drives, including 2 external, I find that Iobit's "Smart Defrag 5 Pro" has served me very well. Being an older machine,, my computer system tends to become fragmented quite easily. Having My "Smart Defrag 5 Pro" set to auto defrag, and running a "Defrag and Optimize" once a week, keeps my system running smooth and well. Iobit is constantly upgrading and striving to make the product even better as time goes by.

I am well pleased with this product. As with all IObit software it is easy to install, use and very reliable. Just set it up and forget it. Smart Defrag has a very small memory foot print so it won't slow down your system. Definitely recommended!

Auslogics Disk Defrag Pro is the advanced version of Disk Defrag Free with extended functionality, including file placement and scheduling options. For example, you can disable defrags if files have fragments that are smaller than 10 MB, have more than three fragments, and are larger than MB.

All of these values can be customized. It should also work just fine in newer versions of Windows, like Windows 11 and Disk SpeedUp might try to install other Glarysoft programs during setup, but you can easily uncheck anything you don't want. Toolwiz Smart Defrag is a small program that installs quickly and has a spotless, minimal interface. It claims to be 10 times quicker than the default defrag tool included in Windows, and can place archive files to a different part of the drive to speed up access to regular files.

You're able to see the number of fragmented files from an analysis and run a defrag really quickly, though you can't see the level of fragmentation that exists on a drive, nor can you schedule defragments to run at a later date. Though it's nice to have a program that isn't packed full of buttons and other toolbars, it's also sometimes unfortunate. For instance, there are zero features that you can customize. If you're looking for a program that's super simple to use and isn't bogged down with confusing settings or buttons, this program is absolutely perfect.

This program officially works in Windows 7, Vista, and XP. We were able to use it just fine in Windows 8 as well.

The really large system restore point files are moved to slower parts of the disk to increase performance for other files. It supports common features found in similar defrag software, like optimizing a drive, viewing a list of all the fragmented files, and checking a drive for errors.

You can optionally run through a Quick configuration wizard to easily set up scheduling or immediately optimize a drive. We tested the most recent version in newer editions of Windows but wasn't able to get it up and running. UltraDefrag can be used for novice and advanced users alike — there are common features that everyone can use but also advanced options if you need to make specific changes to the program.

Common functions like repairing, defragging, and optimizing drives are as simple as any of these other programs. However, if you wish to make changes to the program in general or to the boot time defrag option, you have to know how to maneuver around a BAT file.

MyDefrag formerly JkDefrag can be both a simple and a rather complex defrag program depending on your needs. It works be loading and running scripts on one or more drives. Several scripts are included when you first install it, like to defrag on a schedule, analyze a drive, and consolidate free space.

The default install is just fine for regular users. More advanced users can build their own custom scripts, which can actually be very detailed to deeply customize the way MyDefrag works.

Information about creating scripts can be found in the online manual. However, it still works with newer versions of Windows, like Windows 11, 10, and 8. Disk Defragmenter is the defrag program that already exists in Windows, which means you don't need to download anything to use it.

You can set schedules and defragment both internal and external hard drives. Many of the other defrag programs from this list have many advantages over this one, such as boot time defrags and optimization features.

It throws recommendations for other programs at you at every turn. Still, it makes up for that pestering with performance that rivals most defrag programs for Windows. This program tries to replace Windows' default defragmentation widget by being more advanced and offering more style, features, and customizations. We're not kidding about replacing, either -- the program will turn off your usual defragmenter and install other programs if you don't uncheck those options during install, so be careful.

Once you have Smart Defrag 3 installed, you'll be very happy with its futuristic layout that offers some customization and a nice hard drive map that is a delight to read. It lets you set automatic and boot time defrags, as well -- but you might want to program those to happen when you're not using your computer, as the program took upwards of 30 minutes to defrag when we tested it.

It was smart enough to recognize our SSD and not defrag it, though. The program has an "action center" that claims to recommend performance fixes, but they are all just recommendations for other programs made by the app's developers.

It's not as if those programs are bad, by any means, it's just a little obnoxious to see nonstop advertisements for other programs. Outside of that and somewhat slow performance, Smart Defrag 3 offers everything you'd want in a defragmenting program.

It's a fine replacement for Windows' default and compares favorably to top programs like Defraggler. And Smart Defrag specially optimized the file organization algorithm on Windows To make it more powerful, Smart Defrag 6 also delivers several other useful features. Meanwhile, Auto Defrag and Scheduled Defrag ensure your disks are always optimized to their top performance.

Furthermore, Game Optimize is designed to offer gamers ultra-smooth gaming experience. The last but not the least, Disk Health can help you monitor your disk status in real-time.
