FileSystemWatcher - minimum permissions needed on target directories ?

Question

Hi - Using the .NET FileSystemWatcher http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx to monitor a directory full of files for : Changed; Created; Deleted; Renamed events .

What's the minimum the rights the Account running the FileSystemWatcher needs over the directory it's watching ?

It seems like it would be READ but I can't find that documented anywhere.

Thanks

The underlying API is ReadDirectoryChangesW. The only thing mentioned in the MSDN Library article for it is that the FILE_LIST_DIRECTORY access right is required on the directory handle.
