Defragmenting your hard drive is a crucial part of regular disk drive maintenance. Therefore, using the Best Disk Defragmenter Tools for Windows will help you defrag your drive often or on-demand, whenever your games start lagging, or you start facing trouble while loading up large files. But before we learn about some of the popular defragmentation software, first, let’s understand what Disk Defragging Is? 

What is Disk Defragmentation?

In simple terms, disk defragmentation includes a process of accessing or reading any particular file faster, as all the tiny pieces that make up a single file are placed right next to each other, rather than scattered all over the hard drive. Hence, Defragmentation drastically improves your systems’ performance by making reading a file quick & efficient.

Does Disk Defragmentation Free Up Hard Drive Space?

Yes, this is another useful advantage of using the best defrag software for your Windows. Disk Fragmentation, to some extent, allows you to free up disk space on your system. But how much space can be freed at a time that depends on the type of multimedia file?

How Long Does It Take Defrag a Disk?

Another frequently asked question before we proceed to our list of 10 Best Paid & Free Defrag Software 2020, is how much time is usually required to defrag a disk. Well, the actual duration cannot be indeed defined as it depends on the hardware and processor you are running. If you’re using high-end software, then the defragging process might be wrapped in merely 90 minutes but can also take up an entire day if your system is old or running in a poor state.

    Defragmentation for Linux is a heresy, be careful, Linux fanboys might overreact if you ask them about it. 😉
    Win XP had a decent graphical built in tool to do the same. I remember the old Auslogic 4.5 was good.

      Hi Alex,

      Thank you for your comment. We agree with you, Windows XP had a pretty graphical inbuilt tool for defragmentation. Also, it exists in the existing Windows version too. But using a defrag tool makes the task easier, accurate and can be done faster.
