Purpose for the Dropbox Linking in the iPad app

For the life of my, I can’t figure out why there is a link between dropbox and the Endnote iPad app. Are there workflows I’m not considering? Anybody care to share how the connection is useful to them?

The Dropbox linking in the EndNote for iPad app is designed to make it easier to add file attachments [usually PDF files] stored in Dropbox to records in the EndNote app. Whithin the EndNote app, in the Reference Editor, File Attachments view, click on the “+” icon and a pop-up menu appears that includes the ability to add files from a linked Dropbox account.
