How to Perform Windows 7 Disk Defrag Command Line?

What is disk defrag?

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.

Disk defrag is to rearrange the data scattered in different areas on the disk, in order to read data at one time. This is a necessary aspect of daily maintenance of the computer. By the way, disk defrag is exclusive to HDD, please don’t try to fragment on SSD. Because that will reduce its lifespan.
