Hi,

I am writing a filter driver that will encrypt/decrypt the file. The
problem i am facing is when some application uses memory mapped files
like MS Word or Wordpad to read the file. I cannot intercept the read
call for this kind of files, no IRP_MJ_READ for this kinda files. Is
there something special i have to do for this kind of memory mapped
files.


Thanks
Lokanadham R
