title: How do I handle multiple notification of ReadDirectoryChangesW()?
body: <p>I implemented using ReadDirectoryChangesW() function to figure out any change information of files of the specific directory.</p>
  
  <p>However, the API sent me duplicated notifications. For example, I monitor the directory "C:\abc\" using only FILE_NOTIFY_CHANGE_SIZE flag without watching subdirectory. And, I tried edit and save a image file on the directory. ex) C:\abc\imageFile.png</p>
  
  <p>Then, two or much more the notifications were sent me. Actually, I understand why there are multiple notifications. I read this article. (<a href="http://blogs.msdn.com/b/oldnewthing/archive/2014/05/07/10523172.aspx" rel="nofollow">http://blogs.msdn.com/b/oldnewthing/archive/2014/05/07/10523172.aspx</a>)
  But, I don't know how to handle the multiple notifications.</p>
  
  <p>My goal is synchronizing the image files on some win32 application when the images are changed.</p>
