FileSystemWatcher IncludeSubdirectories仅能够检测有限数量的子目录级别的更改

Question

使用FileSystemWatcher并设置watcher.IncludeSubdirectories = true时。
我只能捕获到两个级别向下的子目录的更改（例如Dir/SubDir1/SubDir2）。但是，如果我想要该目录以外的内容（例如Dir/SubDir1/SubDir2/.../...），则不会引发任何事件。

我使InternalBufferSize = 65536超出极限。有没有办法进入更深的嵌套子文件夹？

这将在网络驱动器文件夹上运行和测试：

using (FileSystemWatcher _watcher = new FileSystemWatcher())
{

    _watcher.Path = directory;
    _watcher.IncludeSubdirectories = true;

    _watcher.NotifyFilter = NotifyFilters.LastWrite
                        | NotifyFilters.FileName
                        | NotifyFilters.DirectoryName;

    _watcher.Changed += new FileSystemEventHandler(Program._watcher_Changed);
    _watcher.Created += new FileSystemEventHandler(Program._watcher_Changed);
    _watcher.Deleted += new FileSystemEventHandler(Program._watcher_Changed);
    _watcher.Renamed += new RenamedEventHandler(Program._watcher_Renamed);
    _watcher.Filter = "*.*";
    _watcher.InternalBufferSize = 65536;
    _watcher.EnableRaisingEvents = true;

    Console.WriteLine("Press 'q' to quit the sample.");
    while (Console.Read() != 'q');
}
