Thanks Theducks and Starson17 - I'm definitely talking about the files on my laptop vs to those within the Calibre library. I'm happy with the Calibre library setup but I actually store my files outside the library. I'll look up the Export option more thoroughly - thanks for mentioning it.
GMRabelink - thank you for the detailed description. I'm going to print it out now and start looking it over.
Thanks again everyone, I really appreciate your assistance and feedback : ))
