SSH to drive letter in Windows 2003

I have a Windows 2003 server running a SSH server (WRQ Reflection), how would I ssh to it and specify a specific drive letter? (like the D: drive)

ex: from another workstation: ssh meuser1@somewindowsbox-running-ssh-server.com d:

When I do that it fails and I get this error: "exec request failed on channel 0" If I simply SSH to that same windowsbox without trying to specify a drive letter I get a Windows (CMD.EXE) command prompt shell on the C: drive. I can then run any windows command.

Thanks

ssh ssh://meuser1@somewindowsbox-running-ssh-server.com/D:/path/to/file as example for D:\path\to\file physical path.
