Is there ANY way to get a path (any - opened, short, normalized) for
paths without TRAVERSE rights?
My thought was traversing affects only File ID and normalized name
query, but I can’t get OPENED name format either on paths without
TRAVERSE right.
If someone did not notice, I am REALLY p***ed at FltMgr this year!

If this is a remote system, there’s not much that you can do. If this is a local system, you can do the operation in a worker thread (where you WILL have the rights.)
Just wait until you find out the nasty gotchas awaiting you when filtering redirectors in Vista…

My questions was WHY can’t FltMgr get ANY type of name without Traverse rights? (I am talking during pre-create here, without File ID)
What you said would make sense for file ID opens only, and that isn’t an issue (nor is it the case here).

I suspect the answer has to do with the fact that the fact that the
pre-create callback runs in the thread context of the caller. I.e. if
the caller doesn’t have traverse rights, you won’t have them in the
pre-create callback. If you do this in a worker thread, it will then be
executing in the context of the kernel. Folks who’ve been doing this
for a while: do I have this correct?

Hello Dejan
Is this happening only for relative open (FileObject->RelatedFileObject !=
NULL)?
Cheers

FltMgr doesn’t need traverse right for regular opens. That’s what the
problem is! This is a regular file open, the name is present in the
FileObject->FileName.
