Defraggler came out at the top of our list for including some sweet extras like a portable version, and the ability to defrag specific files and folders, but all those that made our list had plenty to recommend them. UltraDefrag, for instance, is a great entry-level defragger if you don’t want to deal with anything too complicated.

Best Defrag Software
Product Flag, Rating & Short Summary
Easily scheduled defragging, the ability to defrag specific files and folders, and the chance to exclude specific data from the defrag are all among the reasons why Defraggler tops our list.
A portable version, tons of post-defrag options and the ability to run a defrag while booting earned Smart Defrag a place on our list.
The ability to push less used files to the slower parts of a disc made Disk SpeedUp stand out from the crowd.
An extremely easy to use interface and options put ToolWiz Smart Defrag in our top five.
UltraDefrag came through for its fuss-free approach to defragging.
There’s an easy way to choose the best defrag software available. At least, there is if you’re a bunch of techies with more computers than there is apple pie on the 4th of July. We downloaded, ran some defrag tests and eliminated all those that couldn’t cut the mustard. And wow, did we cut a lot of mustard. The five we chose all came through the competition with their defragging reputations intact.

What’s more, Defraggler can act as a full-on disc cleaner, emptying your recycle bin, running boot time defrags, idle defrags, you name it.

Also available in a portable version for flash drives, Defraggler will defrag you all day long, any way you need, on Windows 10, 8, 7, XP, and if there’s anyone out there still using it, even Vista.

There’s a beauty to the simplicity of ToolWiz Smart Defrag.
Faster than the Windows default defragger, it can put archived files on slower sections of the disc.
The opposite of Disk SpeedUp, there’s no customization here – just clean, minimalist, easy to understand defragging. If you just want to defrag and get on with your day, ToolWiz Smart Defrag is the way to go. It’s important to note though that the program works on Windows 8, 7, Vista, and XP, Windows 10 being conspicuous by its absence.
There is an extremely simple interface for all standard defragging features
You can augment this with optimization if you make changes to a BAT file
Oddly, given the simplicity of most defrag functions here, turning on scheduled defrags is more difficult than it should be
If you saw your first computer yesterday, you could still use UltraDefrag. Pleasingly though, if you’re an experienced programmer, you can still get a good defrag experience out of UltraDefrag, through a series of advanced options.
While all the generally useful functions are easily accessed, more advanced users can actually change the program to their own liking through a BAT file. That means UltraDefrag offers the best of both worlds – efficient simplicity for newcomers and advanced optimization for the more experienced.
