Ok - got it working. Below is the test script.  Finally worked out to do it from your old posts
about this from 2009 :)

Many Thanks.

Yeah, I have a feeling you are running into some problem having to do with non-empty subdirectories.
 Usually some creative sorting, etc., can help.
 The delete task should know how to handle this with filesets; I believe its page in the manual
mentions this very problem. Therefore you might try using the pathconvert task to create a
list of includes for a fileset and pass *that* to the delete task. Keep us updated on your
progress.
