Gentles all....I am going to use Dropbox to back up my Calibre library of over 6000 books. I can sort by title, author, or date added in Calibre. I would like to be able to do the same in Dropbox. When I upload books to Dropbox they show up title first even though they are in Calibre with Author last name/first name. I have used a different Dropbox account to move books from Calibre to my iPad, uploading to a Public folder. They automatically sort to subfolders by author and the subfolders alphabetize automatically. How can I do that with my new library dedicated Dropbox? Thanks!
