need to trap the offline file feature in win2k professional edition

Hi,
I need to trap the offline file feature option in the windows 2k
professional edition. I want to trap the offline feature calls so that i
can move the files from that folder in “%systemroot%/csc” which is hidden
I then need to move this to a secure area, which i can do by creating an
logical drive and encrypting that area.
Part of this functionality is done by cachemov.exe. but the APIs that are
used is from cscdll.dll which is undocumented part of windows API. I have
found out what APIs that it uses but not the parameters that are passed
neither the order of the APIs. Any help or alternatively to find out how
to write a file driver.

thanks,
Inder
