Are you sure though? To take a line directly from the documentation for 
the directoryChanged() signal: " This signal is emitted when the 
directory at a specified /path/, is modified (e.g., when a file is 
added, modified or deleted) or removed from disk." Is this just a very 
misleading line, a documentation bug, or an actual bug in Qt? I just 
want to be sure before I implement this using platform specific API's 
and give up development time I don't have to.
