What is hard disk defragment software?

Hard disk defragment software is specially used to perform disk defrag. As we usually use the computer, data will be constantly written and deleted, which creates fragmentation. When the data is distributed in different positions on the sector, it takes longer for the computer to read and write. This is an important factor that reduces computer performance.

Disk defrag is the process of storing these discontinuous data on a sector into a continuous sector. It reduces the degree of fragmentation and helps increase computer speed. So in order to achieve this goal, we need the help of a disk defrag utility.

Run disk defrag with the best disk defrag programs in Windows

In this paragraph, I will introduce you to three completely different hard disk defragment software. Including Defragment and Optimize Hard Drives, disk defrag Command Prompt and Disk Defrag of AOMEI Partition Assistant Standard. After reading this tutorial, you can choose the appropriate method according to your actual situation.

Method 1. Perform disk defrag with Defragment and Optimize Hard Drives

Defragment and Optimize Hard Drives is a built-in program of Windows 10, which can be used directly without downloading.

Step 1. On the Desktop, click “Start” button, and open "Control Panel".

Step 2. In the Control Panel, navigate toSystem and Security> Administrative Tools” >  “Defragment and optimize drives.

Step 3. After that, the Optimize Drives will be open, you can see the current status of all drives and choose the drive you want to defragment, and choose “Optimize”.


Method 2. Use Command Prompt to perform disk defrag

Command Prompt is also a built-in tool of Windows 10. But unlike Defragment and Optimize Hard Drives, Command Prompt requires you to master the command prompt, which is difficult for most ordinary users.

Step 1. Enter “cmd” in the search bar, right-click Command Prompt and click Run as administrator.


Step 2. In this window, you should type in “defrag C:” and press enter. (C is the drive letter, If you plan to defrag other drives, you just need to modify the C to another drive letter)

Step 3. Wait a moment, you will see the final result of defragmentation.

Tip: Disk Defrag may take several minutes to several hours to complete, depending on the size and fragmentation of the hard disk.

Method 3. Run Disk Defrag of AOMEI Partition Assistant Professional

After knowing how to use Windows built-in programs to optimize disk, I will also recommend a third-party program for defragmentation. The reason for recommending it is that it is better than Method 1 and Method 2. AOMEI Partition Assistant Professional, one of the best disk defrag tools on the market, it is suitable for Windows 11/10/8/7/Vista/XP users. The whole operation process is very simple,  you just need to click with the mouse. More importantly, it allows users to enable scheduled defragmentation to automatically perform defragmentation on a regular basis, which allows us to manage hard disks flexibly.

As we said in the first paragraph, although disk defrag can increase the speed of your computer, you can’t put all your hopes on it, because disk defrag can only improve the performance of PC to a certain extent. If you expect your computer to run more smoothly, Migrate OS to SSD is your best solution.

Note: Please don’t perform defrag on the SSD, because that will reduce its performance.

Step 3. In the schedule settings, you can select drives, and the time mode to defrag the target drives, you’ll have 5 options about time mode.

Step 4. Tick “Conditions” and click “Define”, you can set the rate of fragmentation to trigger the schedule to defrag your disk. And there is “minutes” for idle time, this is to make sure the program won’t hurt the data of other programs. Click “OK” to save all settings.

After reading these three hard disk defragment software, you must be impressed with one of them. The first two are just pure defragmentation programs, while AOMEI Partition Assistant Professional is more comprehensive.
