Hi,

What is the main difference between the filesystem filter driver and the
disk filter driver?

Thanks!

FS filter handles file creation, writing, reading.
Disk filter handles sector read/write coming from a file system.

Of course they do a lot more than that, but it should give you an idea of
what they are.

Hi Tobias,

Thank you for your reply!

I have some question:

#1:can you elaborate your reply above?

#2:Iam facing a problem of how to construct the solution for the
following problem.

Whenever user try to access some volume(C:,D:) either through win32 api or
through UI such as explorer, a popup box has to prompt for
password to access the volume.

Should I write a FS filter driver?

thank you!
