In a FileSystemWatcher, when you are notified of file changes, the system stores those changes in a buffer the component creates and passes to the Application Programming Interfaces (APIs). If there are many changes in a short time, the buffer can easily overflow, resulting in an exception being thrown, which essentially loses all changes. To keep the buffer from overflowing, use the FileSystemWatcher.NotifyFilter and FileSystemWatcher.IncludeSubdirectories properties to filter out your unwanted change notifications. You can also increase the size of the internal buffer through the FileSystemWatcher.InternalBufferSize property. However, increasing the size of the buffer is expensive, so keep the buffer as small as possible.
