You know Zope's integrated online help?

There you would find that files have a method "getSize"
that returns their size.

In the upcoming Zope bock (-> zope.org), you could read
that "dtml-with" can be used to access objects in "foreign"
contexts:

	<dtml-with "news.files">
	  <dtml-var "_.getitem('file01.pdf').getSize()>
	</dtml-with>

or

	<dtml-var "_.getattr(news.files,'file01.pdf').getSize()">

will do.
