thanks to both of you, itimpi and theducks, I'm getting closer.
I've managed to swap the author and title fields in the file after I "save to disk" by selecting the following template:
{authors}/{authors} - {title}
So that's pretty intuitive once you've worked out where to look. Thanks a lot for your help.
It seems there's no way to batch-convert the authors format from "Twain, Mark" to "Mark Twain", correct me if I'm wrong.
I also wanted to add language to the file name.
Based on what I read there:
http://manual.calibre-ebook.com/temp...codes-localize, I tried:
{authors}/{authors} - {title} - {language_strings(lang_codes, localize)}
Based on intuition, I also tried:
{authors}/{authors} - {title} - {language}
Neither works. Does anyone know how to do it? Many thanks.
