These are the best disk defragmenting tools for windows. I was recently tweaking out my hard disk, because it had become very laggy lately, so my first assumption was the drive had been fragmented.
What is Fragmentation?
Fragmentation is a process of building up of gaps in your hard disk. This occurs when you frequently copy and delete large files (ex. games, blu-ray movies, etc). When a file is to be copied, the operating system allocates the necessary disk space, and when it is to be deleted it erases the file contents, and releases the free space to be used later.
As a result, due to continued copying and deletion of files, large gaps are created between files. The Read/Write head of the hard disk moves sequentially so it must go through all the gaps before it locates the file you need, thus increasing the time taken to read a file.
How does Defragmentation help us?
Defragmentation is a process of undoing fragmentation. It compacts all the files in a contiguous location (next to each other), in a sequence so it becomes easy for the read/write head to move, thus taking the shortest time to seek. Defragmentation also allocates all the free space at the end of the hard disk to make sure to remove all the gaps created previously by fragmentation.
To help you out, i have created a list of the best defragmentation tools i use to keep my hard disk running fast.

7. Windows Disk Defragmenter
Of course, there’s also a built in tool in Windows which does all the defragmentation for you and is by default scheduled to carry out defragmentation every wednesday at 1:00 AM although you can also change the frequency from the Settings.
You can also carry out multiple defragmentations (i.e. defragment more than one partition simultaneously). Windows defragmenter first analyzes a disk and then tells you how much percentage has been fragmented. If its more than 50%, then you should run the defragmentation process to ensure all the necessary files are organized neatly.
These were my favorite disk defragmentation tools but if you have knowledge of any other defragging tool to add to this list, do let us know and we will update this article.
