PS.: Disk Defrag may take several minutes to several hours to complete, depending on the size and fragmentation of the hard disk. Step 3. Select the drive you want to defragment, and then click “Defragment disk”. Step 2. In this window, you can see all hard drives and current status on all computers. Step 1. Search for “ Disk Defragmenter” in the search bar, and then open it(search Disk Defragment and Optimize Hard Drives in Windows 10). You can choose one according to the actual situation.

Now, I will show you how to find disk defrag utility and run disk defragment on Windows 11/10/8/7. Windows 11, 10, 8, 7 has built-in disk defragment tools, including Disk Defragmenter and defrag Command Line. Where is disk defrag in Windows 7, 8, 10, 11and how to run it? If you want to optimize the performance of SSD, you can try other methods. Since the SSD can efficiently read the data in the cluster, it is not necessary.
But you should not defrag SSD, due to the different working principles of HDD and SSD, doing that will reduce its lifespan.
Defragmentation is very necessary for HDD. Instead, it sorts out the data address and changes the address of the data from discontinuous to continuous, so that when the computer reads the data, it shortens the search time and improves the speed. Its purpose is not to extend the storage space.
Fragmentation makes it take longer for the hard drive to search data, thereby reducing the speed of the computer.ĭefragmentation is to re-arrange discontinuous data consecutively on sectors so that the hard drives can work more efficiently. In this way, a complete program is stored on discontinuous sectors, which results in fragmentation. If this sector is not enough, the rest part will look for another sector. The program installed later will first fill up the sector of the deleted program. But when you repeatedly delete and download, the problem occurs. In the beginning, all programs are arranged in order on the sectors of the hard drive.
