I've been having this question since the announcement. I watched a review of iOS 11 Files app on the iPad Pro 10.5, it was showing that the "On my iPad" tab on the app was empty, and the New Folder button was greyed out. I know, it's a Beta release, but what should we expect when iOS 11 hits our devices? Will it let us create new folders locally on our device? Will it be possible to copy files from one app to the other, directly from the Files app? And, the most important question, will it be possible to download files from Safari directly to the Files app, but also on the background?
