lets say we want a hyperlink for each file :

  <walk dir="/home/username/Desktop">
    [link to="<d>filename</d>"]<d>filename</d>[/link]<br>
  </walk>

  or a hyperlink and a delete link :

  <walk dir="/home/username/Desktop">
    [link to="<d>filename</d>"]<d>filename</d>[/link] -
    [link action="deletefile" filename="<d>filename</d>"]Delete[/link]<br>
  </walk>
