command line defrag

Is there a command line driven defrag tool that will work from Win98SE at the DOS prompt? And not from a DOS window, but from the true command prompt?

Thanks all.

No.

You could in 95 but not 98 and Me.

I wouldn't recommend something like you are looking for, unless you want all your files with long filenames transformed into 8.3 filenames. For example: Longfilename.Txt would end up as Longfi~1.Txt. If you also have a file with the name Longfilenamed.Txt, it would end up as Longfi~2.Txt. In short, general confusion and/or mayham may result.
