What the Kobo driver does is to write the subtitle into the database entry for the ePub. This does require a second connection since the database entry is created as part of the import procedure.
The subtitle field being added to the Kobo Utilities was just to keep it as close as possible to the one used by the Kobo driver.
My template for storing books on my Kobos does not use the subtitle. I try to keep the filenames as short as possible to avoid having them truncated.
Code:
Ebooks/{author_sort:sublist(0,1,&)}/{title} - {authors:sublist(0,1,&)}
Ebooks is a directory in the root of my Kobos' exposed storage. Under that directory, directories are created based on the first author in the author-sort list (that is what the sublist(0,1,&) does) with the filename inside the directory based on the title followed by the first author in the authors list.
This was required when I was finding that some books required too many characters for the title and list of authors yet I like having the full list of authors available for searching. calibre uses a maximum path length of 260 characters to keep compatibiliy across the multiple operating systems and file systems it runs with. |
Thank you for taking the time to explain all this. I'm grateful
