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.
The following example shows how to create a FileSystemWatcher to monitor file changes (creates, deletes, renames, changes) occurring on a disk drive. The example also shows how to properly receive error notifications.
