6 Best Defrag Software For Windows 10 To Speed Up Your Pc

What Is Defragmentation?

Defragmentation is a process reducing the degree of fragments of a particular file or whole disk.  This is done by locating the fragmented parts of a particular file and rearranging and restoring to make as few fragments as possible. Defragmentation overall reduces the time spent to access the file and enables efficient usage of the storage.

For instance, let’s say you deleted a 2GB video file from your hard drive. Now that block which held that 2GB file will get empty but the blocks beside it will still hold certain files.

When you try to add new files to your hard drive, in order to use the empty spaces, the empty spaces will be used and new files may be stored in parts. When you try a new file of, let’s say, 3GB, then 2GB of it will be stored in the empty blocks to make use of the space, and another 1GB will be stored somewhere else. This happens on a larger scale with hundreds and thousands of fragments which increases the time taken to locate the files.

For defragmentation, you can use the inbuilt Defrag tool, available on almost all versions of Windows OS, however, it is not recommended. The inbuilt defragger is slow, inaccurate, and inefficient. There are a lot of third-party options available on the web. So, to make things easier for you, here I have made a list of 6 of the best defrag software for Windows 10. Let’s check out each of them.
