In order to support Paging IO, and memory mapped files, will i need to add
FastIO support to my file system driver?

Notepad uses memory mapping. If it fails, it is probably because you don’t
set up FileObject->SectionObjectPointers.

Hi,
I have implemented the IRP_MJ_READ dispatch routine for my file system
driver, and I am currently in the process of testing the dispatch handler…
I have managed to open a small 1k byte text file using Wordpad, however
notepad fails to read any data from the file and treats it as an empty file.
Why is this? how does notepad actually read the data from the file?!
Any advice appreciated
Regards
James
