Matthew >>> Thanks for the thought you put into this.  In fact I'd 
already done the deletions manually, as there turned out to be few empty 
directories.  But your solution, and question, look interesting - even 
though I don't yet understand how they do what they do.

Many thanks for your time and interest.
