Probably stupid Dropbox question
My Dad has the Kindle Fire. His Calibre library lives in his Dropbox, but when I went to the Calibre folder on the Fire and tried to download a non-DRM'd .mobi file, it gave me an error such as "can't open this file." Is there a way to force a download in the Dropbox app? I have a file manager and can then move the file to the Books (or Documents) folder.
