I am using v1.15 to convert from .mobi to .epub - nothing fancy
by single or block conversion
The Adding books expression is set as
(?P<author>[^_-]+) -?\s*(?P<series>[^_0-9-]*)(?P<series_index>[0-9]*)\s*-\s*(?P<title>[^_].+) ?
I have not changed this
the calibre screen shows
title Authors Date Size (MB) Tags
Dirk Gently's Holistic Detective Agency Adams, Douglas 16 Dec 2013 0.1
Series
Dirk Gently
The save to disk format is currently
{author}/{series:||/}{title} - {series}{series_index:0>2s| -|- }{author}
The output in the kindle calibre library
has a folder Adams, Douglas
with a subfolder Dirk Gently's Holistic Detective Ag (356)
and a file Dirk Gently's Holistic Detectiv - Adams, Douglas.epub
what I would like would be:
Adams, Douglas>Dirk Gently>01 Dirk Gently's Holistic Detective Agency.epub
which is what I think thw Save to disk format implies
