Thanks a lot. This I somewhat understand, but what I have no clue about is the syantax in Calibre. If
Code:
(?P<title>.+) - (?P<author>[^_]+)
can read a file named like "t_i_t_l_e - firstname_lastname.format" correctly, what would work on the filenames I mentioned? Can you explain that to me? I am totally new to this and have no coidng knowledge. Thanks.
