I recently purchased a Sony tablet and the Sony Reader application for some reason picks up both the orginal file and the converted file from calibre. As a consequence every book is duplicated in the Reader application library.

It may be my imgination, but I thought when the change was orginally made (to maintain both orginal & converted files) there was also an option to revert to the orginal behavior ( keep converted file only).

Does anybody know if that's possible. I have attempted going through the preference options but I have not found anything that would prevent calibre from retaining the orginal file.

Thanks
