Hi,

you need to use recursive calling. Please inspire yourself with this DTML
Method called "x_ST"" that deletes all images in folders "s" or "t"
recursively if they present:

<dtml-in "objectValues([    'Image',
                            'Folder',
                            'ZipFolder' ])" skip_unauthorized>
  <dtml-if "_['sequence-item'] in ('s', 't', 'xs', 'xt')">
      <dtml-let container=this>
        <dtml-in "objectValues(['Image'])">
          DEL: <dtml-var absolute_url>
          <dtml-call "container.manage_delObjects([getId()])">
        </dtml-in>
      </dtml-let>
  </dtml-if>
  <dtml-if "(meta_type=='Folder') or (meta_type=='ZipFolder')"
    ><dtml-with sequence-item
      ><dtml-var x_ST
    ></dtml-with
  ><dtml-else
  ></dtml-if
></dtml-in>
