title: Change a File's ACL to Allow Full Access for Everyone
body: <p>How do I change a file's owner to <code>Everyone</code> and also allow the <code>Everyone</code> object <code>Full Access</code>?</p>
  
  <p>Are there any APIs available for this? Do I have to use P/Invoke?</p>
  
  <p>I searched everywhere but can't find anything to do this.</p>
