Apple’s iOS 11 introduced a new app known simply as Files, which lets you view and access all the files you’ve stored on online services such as iCloud, Box, Dropbox, and Microsoft OneDrive. You can open a file directly to work with it on your iPhone or iPad. You can copy a file from one service to another, and you can tag files to access them more quickly. Let’s check out the Files app to see how you can work with your favorite online files.
