[defrag multiple drives from command line?]

Is it possible to defrag multiple drives, sequentially, from the DF command line?  If so, how?

[Forcing Shutdown]

Having discovered that Defraggler cannot force the shutdown of a locked XP machine. The Microsoft shutdown.exe has a -f (force shutdown) switch that does shutdown a locked machine, I would like to suggest Defraggler incorporate such a "force shutdown" function.

 

Thanks!
