Anyone has had success with some of these “dual tipped” flash drives I see sold online – USB on one end and Lightening on the other. Articles and testimonial mostly show people either (a) pulling photos off their phones to open up memory on their phone or (b) using the external drive to let you overcome some memory shortage on your phone (or iPad) and letting you play a movie on your mobile device that you loaded onto one of these external little flash drives via it’s Lightening tip.
My concern is – is it possible to get a file that is an email attachment and ‘move’ it to such a flash drive? The newer iOS has a “Files” feature but in my experiment I was only able to access items I stored in iCloud, and not an attachment to an email. Compared to my iMac with a trackpad and it’s distinctive operating system, I find my iPhone and iPad don’t seem as flexible when it comes to access and moving files.
