WDM for file system filter driver?

Hi,
Is it possible to write a WDM driver for a file system filter driver? So
that I can have a single driver for both Win 98 and Win 2000 platforms. I am
not familiar with WDM and would like to hear some suggestions from the list.
Any book recommended for WDM? Thanks in advance!

Regards,
Sin Lam

No. WDM is only for hardware devices, not for file systems or file
system filter drivers.

Er, yeah, the problem is that the Win9x IFS manager and the filesystem
drivers do not interact via anything like the WDM/NT model of device-
objects, IRPs and file objects. The FSDs are VxDs. So a WDM filter
has nothing to attach to.
