question about the Rename actions of MS .doc file

NTFSD
1

when saving the .doc file, office will have two rename actions, first
rename .doc to ~WRL****.tmp, next rename ~WRD****.tmp to .doc.

I want to encrypt the .doc file before the second time rename action. My
method is to encrypt ~WRD****.tmp to ~WRD****.ice, next rename
~WRD****.ice to ~WRD****.tmp, but this method have the permission
issure.So I want to ask how can I encrypt the .doc file before the second
time rename action?

another question is can I do the same rename operations as the office?
first rename away .doc file, than rename another encrypt file to the .doc
file.

Thanks a lot!

Are you trying to do this work in a file system filter or other kernel
mode component or in user mode (WIN32) application?
