We're going to assume that you have more than two levels in your tree. Because of this, you are going to have to write a recursive macro. First, your HDF is going to look something like the following:

    Files.0.Name = Desktop
    Files.0.Type = dir
    Files.0.Sub.0.Name = Bookmarks.html
    Files.0.Sub.0.Type = file
    Files.0.Sub.1.Name = History.txt
    Files.0.Sub.1.Type = file
    Files.0.Sub.2.Name = Resume.doc
    Files.0.Sub.2.Type = file
    Files.1.Name = .cshrc
    Files.1.Type = file
    Files.2.Name = .login
    Files.2.Type = file
    Files.2.Name = Mail
    Files.2.Type = dir
    Files.2.Sub.0.Name = inbox
    Files.2.Sub.0.Type = file
    Files.2.Sub.1.Name = received
    Files.2.Sub.1.Type = file
    Files.2.Sub.2.Name = sent
    Files.2.Sub.2.Type = file
    Files.2.Sub.2.Name = postponed
    Files.2.Sub.2.Type = file

Ok, first the simple version:

      <?cs def:display_files(files) ?>
         <ul>
         <?cs each:file = files ?>
	   <li><?cs var:file.Name ?></li>
	   <?cs if:file.Sub.0.Name ?>
	     <?cs call:display_files(file.Sub) ?>
	   <?cs /if ?>
	 <?cs /each ?>
         </ul>
      <?cs /def ?>

      <?cs call:display_files(Files) ?>

This version relies on HTML to format your list. Notice how we check both the existance of the sub element before we recurse, because otherwise we'll get an extra ul pair, which in most browsers will cause extra whitespace. Perhaps you don't want to use the HTML like this, for spacing or other issues. You could always pass an string that grows down the recurse that provides the indention:

      <?cs def:display_files(files, spc) ?>
         <?cs each:file = files ?>
	   <?cs var:spc ?><?cs var:file.Name ?><br>
	   <?cs if:file.Sub.0.Name ?>
	     <?cs call:display_files(file.Sub, spc + "&nbsp;") ?>
	   <?cs /if ?>
	 <?cs /each ?>
      <?cs /def ?>

      <?cs call:display_files(Files, "") ?>

This version keeps growing a string of non-breakable spaces to place in front of the file name, which makes for a slightly indented view. You could then add something which checked the type and issued and icon between the spaces and the name, etc.
