How does Windows store files on the hard drive? In the beginning, all items are arranged in good order on the sectors of the hard drive. But when you save, change, or delete files, the problem occurs.
For example, when you create a new document, Windows will find a place that is just enough for it and save it there. If you add new content to the document and the original place is not enough to store the additional file, Windows will look for another sector on the hard disk - probably on a different track or plate.
In this way, a complete file is stored in a different location. This is what we called fragmentation. Over time, file fragmentation becomes more and more. Obviously, it makes the Windows system take longer to locate and open the needed data, which results in a slow PC.
To deal with this issue, this article aims to introduce five handpicked disk defragmenter software that can decrease the degree of fragmentation to speed up your computer.
