IMF_copy or INF_Copy = Mental Ray Map Manager ??

Hi all,

Reading the MR-book and viewing Gnomon tutorial discs, I've seen that the 
maps in mental ray can be converted to *.map so that MR reads them more 
efficiently.
Both the book and the dvds talk about using "IMG CVT *.tif *.sgi" or 
"IMF_copy/INF_copy -r -p *.sgi *.sgi map" but I cannot use these in my
windowsXP 
commandline.

1) how can I use the MR-commandline (or where do I put it?)



I've also read (on this forum) that the "Mental Ray Map
Manager"-command in 
max should do this converting automatically at the beginning of each render 
(when checked)

2) Is this true? If so, how does it work? If not, what does it do? and how?
3) Does it saves these maps, so we can turn it off when rendering the next 
render (and thus save the converting time)?

rgds,
