Defrag software programs are tools that arrange the bits of data that make up the files on your computer so they're stored closer together. This allows your hard drive to access files more quickly.

Defragmentation, in other words, can help improve your computer's performance by making the reading of files more efficient, thanks to the fact that all the tiny pieces that make up a single file are right next to each other.

Still confused? See What Is Fragmentation & Defragmentation? for more help understanding what fragmentation is and why defrag software is helpful.

All versions of Windows include a built-in defrag program, which I've ranked in this list. However, in most cases, a dedicated program, like any of the other free defrag software programs I list here, will do a better job.

I've only included freeware defrag software in this list. In other words, only completely free defragmentation programs — no shareware, trialware, etc. If one of these free defrag programs has started charging, please let me know.

Defraggler

What We Like

Defrags can be run automatically on a schedule
It can do a defrag of the HDD during a reboot
You can defrag specific files and folders
Data can be excluded from the defrag
Can be run directly from Explorer
Lets you move lesser-used fragmented files to the very end of the drive
A portable version is available

What We Don't Like

Might be confusing if you don't want to deal with all the extra options
Doesn't support idle defragging
Installs another program unless you uncheck that option during setup

Piriform's Defraggler tool is easily the best free defrag software program out there. It can defrag the data or just the free space of an internal or external drive. You also have the option of defragmenting specific files or folders and nothing more.

Defraggler can run a boot time defrag, check a drive for errors, empty the Recycle Bin before defragging, exclude certain files from a defrag, run an idle defrag, and selectively move lesser-used files to the end of the drive to speed up disk access.

Defraggler is also available in a portable version for flash drives.

If the Piriform company sounds familiar, you may already be familiar with their very popular free CCleaner (system cleaning) or Recuva (data recovery) software.

Defraggler can be installed on Windows 10, 8, 7, Vista, and XP, as well as Windows Server 2008 and 2003.

During setup, uncheck Try Google Chrome before installing Defraggler if you don't want to install the Chrome browser along with this program.

Smart Defrag

What We Like

Will run a defrag automatically on a schedule
A defrag can run while the computer is booting up
Files you access often can be moved to faster parts of the drive
A portable version is available
Can clean up the drive before the defrag to speed it up
Lots of options for post-defrag, like to reboot
Exclusions can be applied to the defrag

What We Don't Like

Some of the features are only usable if you pay
Can't defrag automatically when the computer is idle

Smart Defrag is great when it comes to scheduling an automatic defrag since there are some very specific advanced settings.

It supports running a defrag on a schedule as well as using boot time defrags to remove fragments from locked files.

Smart Defrag can also exclude files and folders from a defrag/analysis, replace Windows Disk Defragmenter, defrag just Windows Metro Apps, and skip defragging files that are over a certain file size.

Also included in Smart Defrag is a feature which removes junk files in Windows and Internet Explorer. It also clears cache files in other parts of Windows that could help speed up a defrag.

Windows 10, 8, 7, Vista, and XP users are able to install and use Smart Defrag.

Windows 64 Bit Software

Puran Defrag features a custom optimizer called Puran Intelligent Optimizer (PIOZR) to intelligently move common files to the outer edge of a disk to speed up access to those files.

Like some of the other programs from this list, Puran Defrag can defrag files and folders from the Windows Explorer right-click context menu, delete custom files/folders before a defrag is launched, and run boot time defrags.

There are very specific scheduling options available in Puran Defrag like running an automatic defrag every so many hours, when the system goes idle, or when the screensaver starts.

Particular schedules can also be set up for boot time defrags like running it on the first computer boot up of the day, on the first of the week, or the first time your computer boots up every month.

One thing I don't like about Puran Defrag is that it tries to install additional programs during setup.

Puran Defrag is said to be compatible with Windows 10, 8, 7, Vista, XP, and Windows Server 2003.
