Defragment the Boot and Application Files in Windows Vista

1. Open the command prompt with administrative privileges by clicking the Start orb, All Programs, Accessories, right-click Command Prompt, and then click Run as Administrator.
2. Type defrag c: -b (assuming you want to defragment files on your C: drive) and then press Enter on your keyboard. You could also type defrag –b to defrag boot and application files on all hard drives.
3. You won’t see any output in the command prompt during the defrag process.
4. When it’s finished defragmenting a new line will appear in the command prompt.

Note: You can stop a defrag running from the command prompt at any time by pressing Ctrl+C on your keyboard.

   What are the benefits of doing this?
   Does disk degfrag not do this already?
