FileSystemWatcher used to watch for folder/file open

Question

I have browsed around but cannot find any information on what I am seeking, if there is another post that already goes over this then I apologize.

I am seeking help

Answer 1

what you really need is NtQuerySystemInformation enumeration and a timer, that way you can scan the directory and see if any of the files are open. the filesystemwatcher will not give you this info
