Let’s face it: we all want our computers to run as efficiently as possible all the time. One way to achieve this is to defragment your drives, optimizing them for maximum performance. Defragmenting makes your files contiguous, allowing for quicker access.

And while Windows 10 and 11 have built-in solutions to automatically defrag your drives on a schedule, if you’re looking for something more, here are free disk defragment tools you can use for Windows 10 and 11.

1. CCleaner’s Defraggler

The simple interface of Defraggler is a breath of fresh air, which is why it’s at the top of the list. The software quickly analyzes your drives and it gives you the option to defragment individual files in addition to whole drives. This can save you time if you want to defrag only a specific subset of your data.

Click on a specific block and you can pull up the files located on that drive space. There are options for quick defragging and excluding certain files and folders from the defragmentation process. You can also defragment free space as a sort of precautionary defragmentation solution. It is available for Windows 10 and 11.

Download: Defraggler (free, premium version available)

2. Wise Care 365

Although there are paid versions of Wise Care 365, the free version is chock full of features. In addition to defragging and optimizing your drives, you can speed up your PC through other pathways. It offers system cleaning options as well as a level of privacy protection, so it’s not just shoring up your PC’s hard drive performance.

Using the software, you can disable programs that run silently in the background, effectively optimizing your RAM for maximum performance. It also affords a system and hardware monitoring utility. There’s even a floating button to quickly free up some memory on the fly.

3. IObit Smart Defrag

IObit’s Smart Defrag is a defragment tool for Windows 10 and 11 that allows you to optimize apps and defragment free space. (Did you know that defragmenting your hard drives is one way to optimize your power usage?) The program offers you a report when the process is completed so you can check problem files.

There are some boot-time defrag options in the free version, although the ability to defrag registry files is reserved for the paid version. As an added bonus, you can monitor your disk status in real-time.

4. WinContig

While most defragmentation software work primarily on the entire disk drive, WinContig’s focus is on defragmenting single files and folders. This comes in handy if you want to quickly defragment a file or a directory to, say, make a disk-intensive program or game load more quickly.

This allows the software to come in a small package and to run quickly. The nice thing about WinContig is that it’s portable and resource-light.

5. Auslogics Disk Defrag

Auslogics Disk Defrag is only compatible with Windows 10, but it comes with all the features you’ll need from a defragger. It offers file and folder defragmentation in addition to whole disk defrag options, and it even displays the files present in each block.

The paid version adds disk clean-up tools and the ability to schedule defragmentation of your files. The free version has ads, but you can disable them from the settings menu. Once installed, you can create a portable version of the software.

6. Glarysoft Disk SpeedUp

Like WinContig, this free tool from Glarysoft also allows you to defragment individual files and folders, but it also defragments entire drives. It offers the option of boot time defrag so that your system and registry files are error-free.

You can schedule the program to run periodically to keep your PC running smoothly. If there are any files or folders you don’t want the Disk SpeedUp defragger to touch, you can exclude them from being defragged.

7. Puran Defrag

This free tool for defragmenting your drives may have been updated last in 2016, but it has all the features you’d expect from a defrag tool. It’s simple to use and doesn’t confuse you with too many options.

Puran Defrag software

It comes with an auto defrag option that you can have set up to run periodically as well as a low priority defrag option so that you can run the process in the background without consuming a lot of PC resources. The program runs just fine on Windows 10 and is relatively quick in its working, but there doesn’t seem to be support for Windows 11.

8. Toolwiz Smart Defrag

Another defragmentation software with a minimal interface is Toolwiz Smart Defrag. It claims to be able to analyze your drives 10 times faster than Windows’ built-in defragment tool because it uses an undocumented Microsoft NTFS parsing algorithm, bypassing the file system.

Toolwiz Smart Defrag

The program is so minimalist that there is practically no interface, only buttons to analyze and defrag your drives. You don’t have much control beyond these very basic operations. The program hasn’t been updated in a while and may not run on Windows 11.

Download: Toolwiz Smart Defrag (free)

9. UltraDefrag

Another program that hasn’t been updated in a while, UltraDefrag probably won’t work on Windows 11, although it runs on Windows 10. It offers boot-time defragmentation for system files and can process individual files and folders in addition to entire drive volumes.

The interface is simple if a little dated, and you can run a defragmentation process on your drives without the need for too much configuration. If you want to batch process or schedule defrag tasks, you have the option of the console interface.

Go a Step Further With Simple Defrag Tools

While defragging your hard drive can take up to many hours, some of the disk defragment tools we’ve touched upon allow you to target specific files and folders to make things easier and quicker. Others have boot-time defragmentation capabilities to clear up system settings and registry entries.

Whatever your defragmentation needs, if you’re looking for something to replace the built-in Windows Defragmenter and Drive Optimizer, you should find something comfortable for Windows 10 and 11.
