Getting a notification when a local file is accessed in windows

Question

I'd like to get notified when a specific file get accessed (AFAIK, most generally for a Userland code - by CreateFile() / NtCreateFile())

I already know about FileSystemWatcher which should do the same within the .NET environment, But I'm working in plain C + WinAPI.

As for the type of notification , raising a specified Event would be perfect, but sending a callback to be called , will also work.

See FindFirstChangeNotification function in WinAPI and related links.

Alternatively, when functionality of that function is not enough, you can use a filesystem filter driver (write yours or use our CallbackFilter product).

`FindFirstChangeNotification()` seems to be what I was looking for. I wonder if `.NET` implements theirs `FileSystemWatcher` with it. BTW, I can't upvote due to lack of reputation, so have my virtual +1 . – friedrich kuhler Nov 07 '13 at 13:15
@friedrichkuhler Yes, FileSystemWatcher is just a wrapper. – Eugene Mayevski 'Callback Nov 07 '13 at 13:58
