Defragmenting the disk is an important maintenance task that helps improve the performance and efficiency of your computer. In the Windows environment, you can easily perform disk defragmentation using the Command Prompt (CMD). This article will guide you through the steps of defragmenting your disk via CMD in Windows, providing practical examples and commands.

Examples:

1. Open the Command Prompt: Press the Windows key + R to open the Run dialog box. Type "cmd" and press Enter to open the Command Prompt.

2. Check the current fragmentation status: In the Command Prompt, type the following command and press Enter:

   defrag C: /A

   This command will analyze the fragmentation level of the C drive and provide a detailed report.

3. Perform a quick defragmentation: To quickly defragment the disk, use the following command:

   defrag C: /U

   This command will consolidate fragmented files on the C drive without optimizing them. It is a faster option but may not provide the best optimization.

4. Perform a full defragmentation: For a more thorough defragmentation that optimizes files as well, use the following command:

   defrag C: /O

   This command will consolidate fragmented files on the C drive and optimize their placement on the disk for improved performance.

5. Schedule automatic defragmentation: You can schedule automatic defragmentation to ensure regular maintenance of your disk. Use the following command:

   defrag C: /O /M

   This command will defragment the C drive, optimize files, and create a schedule for automatic defragmentation.
