Manually run dfrgntfs.exe?

Hello.

I got annoyed with Windows XP Pro. SP3's dfrgntfs.exe that runs
automatically in the background after about ten minutes or so of idling.
So I disabled it through TweakUI. I tried to manually run dfrgntfs.exe,
but it said "command line operation of Disk Defragmenter is not
supported." Is this the same disk defragger through
%SystemRoot%\System32\dfrg.msc?

Thank you in advance.

I think so.
I deleted dfrgntfs and dfrgfat and ran drfg.msc.
Both files were recreated. Probably copied from dll cache.
Running Defrag via a dos prompt also recreates those two files.
I prefer to run the dos command version.
