What is disk defrag?

Your PC should be responsive and fast when it’s new. However, over time, even the PC with most high-end hardware can become slow and sluggish, especially if you frequently save/resave and delete your files since in this way, disk fragmentation is generated which badly affects your computer speed.

As we all know, a file combined with different segments that are contiguous to each other when stored on a hard disk. However, when the file is fragmented, the segments get scattered across the hard drive which makes it harder to locate the file itself. Thus, the speed of your PC goes down.

To restore your computer to its previous status and eliminate disk fragmentation, you’re supposed to run a disk defrag which is a way to put those segments back together to reduce the time for the file to be found.

Method 2. Try a third-party disk defraggler

By enabling schedule defrag on Windows 10, you save much time and energy and efficiency gets improved as well. However, as you can see, the Windows built-in defraggler doesn’t give many options for auto-defrag – it’s just not flexible enough. Meanwhile, many people complain that the disk schedule defrag doesn’t work for no reason sometimes.

So, here, I’ll recommend a more full-featured alternative - AOMEI Partition Assistant Professional – a powerful and versatile third-party software utility that’s able to schedule defrag your hard drives more efficiently. It not only enables you to defrag daily, weekly, and monthly, but also, it allows you to decide at which clock, on what conditions, and even whether at startup or logon on to start a defrag. What’s more, the AOMEI product is also a practical disk management program with which you can perform different operations including SSD secure erase, SSD 4K alignment, and partition check.
