I found some .vdk files here… <Dragon Computer Consultancy <http://www.dragon-it.co.uk/dragon-it.nsf/MainFrame?OpenFrameSet&Frame=East&Src=/dragon-it.nsf/docs/dragon?OpenDocument&AutoFramed>>

I could be doing something wrong in using the DOS, I just turned
on the Dragon (my first) last night.  Never had one to play with before.
