Missing events in ShellChangeNotifier

Question / Problem

I'm using the ShellChangeNotifier control to monitor directories for changes. Sometimes I only receive FolderUpdate notifications for a folder, instead of explicit events for file creation, removal, etc. What is going wrong?

Answer / Solution

ShellBrowser relies on the Windows notification system to monitor changes. Sometimes individual notifications are summarized into bigger chunks. It depends on the size of the folder, the number of affected elements and also the type of folder whether this happens or not. Unfortunately this behavior cannot be influenced.
