This is a strange thread to post this in, as there is a calibre forum here, and this has nothing to do with iPad.
I will assume you are talking about the file names you are seeing in Finder for filenames for your books.
· is the
HTML entity for 'Middle Dot' character (U+00B7 unicode).
calibre has a template to control generation of the file name from Title and Author. It's found in Adding Books preferences. The default is this Regular Expression:
Quote:
|
(?P<title>.+) - (?P<author>[^_]+)
|
Did you change this? If not, you should be getting hyphen and not Middle Dot. In any case you can
Restore defaults and I think that will trigger rename of the book filenames.
But please consult calibre documentation, or post in calibre thread for any follow up.
