Being a Newbie, too, 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 appreciated) called
Bulk Rename Utility
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.
Cheers
