Hello,
i tried everything

but when it comes to save my files to disk, following will happen:
i use: {author_sort}/{series} - {series_index} - {title} - {authors} - {isbn}
because i want to have:
SERIE - NO. - BOOK NAME - AUTHOR - ISBN
all fine WHEN the book has a SERIE
BUT IF NOT
the file name is like this:
- - SERIE - NO- BOOK NAME - AUTHOR - ISBN
i dont want those two " - - " at the beginning.
how can i remove them?
thanks a lot
