[ros-dev] FullFAT replacement for Fastfat.sys

[Aleksey Bragin]

The NT specific part would be file objects and related operations,  
IRP handling is partially done already. Actually I stopped at a level  
which already required initial volume mounting, and traversing the  
root directory iirc. So it might really be quite fast (development  
speed wise).

Of course, relying on a reference fastfat from WDK would be also fun  
and good, Alex is right that probably up to 70% of its source code  
aren't needed for us, and the other 30% would serve as a good  
reference. But if there is a way to avoid MS copyrighted code, and  
there is a great developer who offers his help - FullFAT would be a  
way to go.


WBR,
Aleksey Bragin.
