[Zope] total size of files in a folder

[Cornelis J. de Brabander]

I was not sure about your first dtml-let either, so I tried your code myself
and ended up with:

<dtml-call "REQUEST.set('total_size',0)">
<dtml-in "objectValues(['File'])">
 <dtml-call "REQUEST.set('total_size',total_size+size)">
 <dtml-var title_or_id><br>
 <dtml-if sequence-end>
  <dtml-var total_size>
 </dtml-if>
</dtml-in>

which works.
