Best Free Defrag Software
Fragmentation, Defragmentation, and Optimization
Fragmentation happens due to continuous copying and deletion of data or files. The Defragmentation process locates and combines the file fragments together, and rearranges them into fewer to no fragments. The Optimization option present in various defragmentation programs (like auslogics disk defrag software for windows etc), fills the empty gap between files. When the defragmentation has finished, and the files have been combined together and rearranged into fewer segments, there will still be empty spots in-between files.
The optimization moves the files, and places them one after another so that all of the files on your hard drive is present as one big sequential block, and the rest of the drive is empty space.
Windows has an inbuilt tool for defragmentation called Defragment and Optimize Drives, which automatically works and defragments your hard drive in background.
But, if you want to have more control over the defragmentation process, and want more advanced features, then you’ll have to turn to third-party solution.
Here are some of the best free disk defragmentation software for Windows.
The Auslogics Disk Defrag is one of the most popular and highest rated defragmentation software for Windows.
Auslogics has three modes – Defrag, Defrag & Optimize, Quick Defrag. The Analyze features analyzes the hard disk for fragmentation and lists the fragmentation state of drives in graphical form. The Defrag mode first analyzes the disk and performs deframentation. The Defrag & Optimize mode works in three phases – the first phase analyzes the disk, the second phase defrag the fragmented disk, and the third phase optimizes the whole disk and remove fragmentation. The Quick Defrag mode starts the defragmentation without analyzing the disk fragmentation to save some time.
The Advanced features of this defrag software included in the program are Defrag File, Defrag Folder, Check Selected (disk partitions), Check & Correct Selected (disk partitions), and Wipe free space on selected (disk partitions).
- Lightweight and Fast
- Support Windows 7 and Windows 8 and Windows 10
- Disk Cleanup and Checkup
- Defragment Registry
- Offline Defragmentation
Piriform, the same company that develops CCleaner, develops Defraggler. Defraggler is a strong competitor for the best free defrag software for Windows.
Like Auslogics, it has an Analyse button, which performs the first step of defragmentation process. It has two defragmentation modes – Defrag, and Quick Defrag.
One nice feature this software has is the Benchmark Drive, which scans and rates the disk. A perfectly fine disk will display GOOD in green colour, but if your disk has some errors then the displayed label will be ERROR… in Red.
Along with the drive defragmentation, you can also defrag specific files and folders with the Defrag File and Defrag Folder options respectively.
Advanced features include in this defrag software, Check Drive for Errors, and Defrag Freespace. You can set the defragmentation priority to be either Normal or Background. After the defragmentation has finished, you can either Close Program or Shutdown the computer.

- Disk Health Check
- Lightweight on System Resources
3. Disk SpeedUp
Disk Speedup is created by Glarysoft, the creators of Glary Utilities Program.
The first step in this defrag software is, defragmentation process, for finding the disk fragmentation percentage by analyzing the disk. Click the Analyze button to do that. Disk SpeedUp has two modes for defragmentation – Defrag, and Defrag and Optimize. The Defrag mode is the faster one because it does not move files to optimize the disk. The second mode, Defrag and Optimize, is time consuming but it optimizes the disk for better performance and increase access time. Along with the total disk defrag, you also get the options to Defrag a file or Defrag a folder.
- Auto Defrag

- Supports All Major Windows OS
4. Ultra Defrag

Puran Defrag is available as a standalone application as well as a tool in the complete Puran Utilities suite.
There are various Additional Operations available for its users such as Fill Gaps To Avoid Frequent Fragmentation, which is what other defrag software call Optimization process, Optimize Directories For Faster System Access, which moves the directories to faster area or at the beginning of the disk, and Free Some Space For Windows Temporary Files On Faster Disk Area.
It is a great feature to free space for temporary files because temporary files such as browser cache are often in-use by programs, they are created, accessed, and deleted regularly, and placing these temporary files in faster disk area makes the program run better. Puran Defrag includes a proprietary technology called Puran Intelligent Optimizer (PIZOR), which works with other features of the program to boost the overall system speed and performance.
