Robocopy not a recognised command


I wish to move my Program Files and Documents and Settings directories to a secondary HDD (as demonstrated by this article - tested(dot)c o m/tech/2341-how-to-move-your-apps-and-user-files-to-a-secondary-drive/).

I have downloaded windows 2003 system tools which contains the robocopy functionality and I have installed the Recovery Console from my XP disc.

The problem I am having is that the Recovery console doesn't recognise robocopy as a valid command. I would really appreciate help with this if anybody has any ideas as to why this is happening. Thank you for your time.
