Application and Boot file Defrag

I dont get this?

Application and Boot file Defrag

This type of defrag pushes all commonly used programs and boot files to the edge of the hard drive for faster access. Windows XP normally schedules this every three days when it is idle, however you can force it to do this by using the b switch anytime

i.e defrag c: -b

So how do i do this? and will it improve the performance of my pc?

I have tryed this and just a black box comes up! does that meen its doing it?

WinXP normally does this by default in the background (http://www.extremetech.com/article2/0,3973,1149277,00.asp) so why would you want to run it manually. Do you have a reference for the use of the -b switch.
