[BetterRed]

@Latios would seem to have a point. If an Author's name ends in a dot (.) it seems to get a different treatment to a Title that ends in a dot (.),

On Windows/NTFS I created this book



Then with these StD basic settings



... and this template

{title}. {author_sort}. {:'format_date (raw_field ('pubdate'),'yyyy')'|. |}

I get this file name

Hello_ Better Red_ . 2000.epub

And with this template (the one Latios posted)

{author_sort}. {title}{:'format_date (raw_field ('pubdate'),'yyyy')'|. |}

I get this file name

Better Red_ Hello.. 2000.epub

Curious : @Latios - why do you want dots in the file names?

BTW, in my Test library (which is the one I was using) I don't swap first and last names to create Author Sort.
