In this tutorial, I will show how to perform Windows 7 disk defrag command line step by step. The disk is originally a continuous blank area. When you install programs on the disk, these programs will be arranged on the disk in order. But when you uninstall or delete a program, the problem occurs. The newly installed programs will no longer be arranged in the previous order. They will fill the area of the deleted program first.
When the area is not enough, they will look for another new area. Repetition will produce fragmentation. Fragmentation will cause the hard drive head to spend more time searching for data, thereby reducing the reading speed. Note: I saw this tip on TechNet but I wanted to expand on it a little bit. As they mention, the syntax for the Windows 7 version of the command line version of defrag. The various defrag options give you a significant amount of control with regard to this common utility. Probably the most common command with this technique would be:.

Syntax The defrag. Click the Start button and type cmd in the Search box. Navigate to the cmd. If this sector is not enough, the rest part will look for another sector. In this way, a complete program is stored on discontinuous sectors, which results in fragmentation.
Fragmentation makes it take longer for the hard drive to search data, thereby reducing the speed of the computer. Defragmentation is to re-arrange discontinuous data consecutively on sectors so that the hard drives can work more efficiently. Its purpose is not to extend the storage space. 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.
Yes, you do. Defragmentation is very necessary for HDD. Since the SSD can efficiently read the data in the cluster, it is not necessary. If you want to optimize the performance of SSD , you can try other methods. Windows 11, 10, 8, 7 has built-in disk defragment tools, including Disk Defragmenter and defrag Command Line. You can choose one according to the actual situation.
Step 1. Step 2. In this window, you can see all hard drives and current status on all computers. Home How to What is defragmentation How to defrag in Windows 7 using command line. So what exactly is defragmentation and how is that help the performance of my system? To find out, we can use the built-in disk fragmentation utility. If you are a geek like us, you can also try to use the command line disk defragments. Hopefully, now your hard drive will be smooth and increase your system performance.
