Command: Defrag

Features: Defragmentation of disk

Syntax: Defrag Volume [/a] [/v][/f]

Parameter: [/A] parameter only analyzes the current disk and prompts whether the disk defragmentation should be performed on the disk [/V] parameter to detail the results of the analysis. Volume A reference letter, such as "C:".

Combat: When defragmenting a disk in Windows, if the disk has less than 15% of the total free space, the program will not be able to do so, and if you add parameter/F (hint: You can also use "-" instead of the original "/" in 2003), you can force defragmentation of the disk.
