Now, you have to admit that fragmentation originally arises when your computer, being the genius that it is, created too much disk space to spare when you created a new file. That space must not be wasted and will be converted as a fragment for something else when it is created.

But we can help out our hard drive and make it a bit easier to find all the bits and pieces of some data that you tend to access often. So here are 4 Best Defrag Software for Windows to help you out with just that, in 2019. Let’s begin.

Disk Speedup

Disk Speedup is one of the simpler ones out there when it comes to Defrag software for Windows OS. What I find refreshing about this software tool is that you can set your custom range for the sizes taken up by directories, so they can be listed for defragmentation only if they fall under your specified range of storage sizes. That’s pretty smart if you ask me.
