Hi. Congratulations for this wonderful plugging!
I want to create a download link that opens a new window with this link to iBooks store: https://itunes.apple.com/es/book/carta-enciclica-sobre-la-fe/id672201368.
If i pun this link in File URL, i create a download link in post, this download the html page of iTunes. It's possible to open a link in new window?
