FileSystemWatcher event trigger problem(s)

It seems like , FileSystemWatcher triggers events more than once. Here is my settings ;

 watcher = new FileSystemWatcher();
 watcher.Path = @"D:\testSpace";
 watcher.InternalBufferSize = 1024*64;
 watcher.Deleted += Triggered;
 watcher.Changed += Triggered;
 watcher.Created += Triggered;
 watcher.Error += ErrorOccured;
 watcher.NotifyFilter = NotifyFilters.LastWrite;
 watcher.IncludeSubdirectories = true;

 watcher.EnableRaisingEvents = true; 

• If you change a document , Document changed event triggered twice.

• New folder created event does not get triggered unless a new file created under the folder.

• Deleted event not fired ( tried using shift delete as well)

do you guys 开发者_开发百科know any work around for these issues ?

FileSystemWatcher:

Common file system operations might raise more than one event. For example, when a file is moved from one directory to another, several OnChanged and some OnCreated and OnDeleted events might be raised. Moving a file is a complex operation that consists of multiple simple operations, therefore raising multiple events. Likewise, some applications (for example, antivirus software) might cause additional file system events that are detected by FileSystemWatcher.

The solution to your 1st issue is described in the link.
