title: How to copy folder permissions by robocopy?
body: <p>I used robocopy like this:</p>
  
  <pre><code>robocopy D:\123 D:\456 /e /copyall
  </code></pre>
  
  <p>than I changed the permissions of folder <code>D:\123</code>(change ACL,include all files and subfolders), I want to copy the new permissions of folder <code>D:\123</code> to folder <code>D:\456</code>(include all files and subfolders). so I used robocopy like this: </p>
  
  <pre><code>"robocopy D:\123 D:\456 /e /copy:sao"
  </code></pre>
  
  <p>Update permissions(ACL) for all files succeeded,but the permissions(ACL) of the folder update failed,the permissions of all folder is not changed.
  How can I update the permissions(ACL) of folders?</p>
