title: Enable ACL permissions on shared folder in Synology DSM 5.2
body: <p>My Syno DS213+ is running on DSM 5.2-5644</p>
  
  <p>I have several shared folders that don't have the option to edit ACL permissions, because they were created before DSM 5.0</p>
  
  <p>In the <a href="https://www.synology.com/en-global/releaseNote/DS213+" rel="nofollow noreferrer">release notes of DSM 5.0</a>, under "What's New in DSM 5.0", topic 5, it says:</p>
  
  <blockquote>
    <p>For shared folders created in DSM 4.3 or earlier, you can either
    convert the existing permissions to Windows ACL, or leave the
    permission unchanged.</p>
  </blockquote>
  
  <p>And also, in the syno knowledge base, i found <a href="https://www.synology.com/en-global/knowledgebase/tutorials/453#t2" rel="nofollow noreferrer">this article</a> on how to enable these ACL permissions.<br>
  In topic "To enable ACL for a DiskStation shared folder", point 3 says:</p>
  
  <blockquote>
    <p>Click Edit, click the Windows Access Control List tab, select Allow
    editing Windows Access Control List, and then click OK.</p>
  </blockquote>
  
  <p>However, the <em>Windows Access Control List tab</em> is not available in DSM 5.2</p>
  
  <p>Does anybody know how to enable the ACL permissions on a shared folder in DSM 5.2?</p>
