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.
