ShellChangeNotifier Class

Use this component to get information about changes in the file system (copy, move or delete operations) and other changes relevant for shell operations. Different event types can be specified using the EventFilter property. Use the Directories or ItemIdList property to specify what folders should be tracked. You can implement events Change or ChangePIDL to receive and handle the notifications.
