Answering my own question, I've searched the Calibre forums and found this
VERY useful post by Penguinaka
https://www.mobileread.com/forums/sho...d.php?t=138792
There are MANY variations offered up here.
obtw... I'm using a 'freebie' tool
(Donations are always appreciated, Right, Kovid?)
called
Bulk Rename Utility (BRE)
http://www.bulkrenameutility.co.uk/Main_Intro.php
and the RegEx expressions from Penguinaka (and others) allow me to
do all the clean-up BEFORE I try to add to Calibre.
The Help file in BRE gives an overview of RegEx, the most common
Meta-thingies and some other examples and their Website has links
to the Forum on Regex - all the quick start stuff you'll need!??
Happy Spring Cleaning
Cheers
