I am trying to use Calibre to organize my ebooks into genres and subgenres. I followed
these instructions to create the `genre` metadata item.
I created a `Poetry` sub-genre inside a `Literature` genre and then from `Preferences > Saving books to disk` I changed the
saving template to `{#genre}/{title} - {authors}`. Then when I tried saving from
here, Calibre just saved the ebook directly to the directory I had chosen without creating the
directory structure I was hoping it would, i.e. `Literature > Poetry`. How can I get it to do that? Thank you.
