About CDirectoryChangeWatcher:
The class CDirectoryChangeWatcher does all the grunt work of watching a directory. It creates a worker thread that is waiting for directory changes to take place via its use of the ReadDirectoryChangesW Win32 API function. Multiple directories can be watched with a single instance of CDirectoryChangeWatcher, and directories can be added and removed from the watch at any time.
