One task that was always easier on macOS was to rename multiple files at once using Automator. The Files app on iOS/iPadOS doesn’t have a lot of bulk actions. But I finally cracked it with Shortcuts to let you batch rename files on iOS and iPadOS. My shortcut lets you do three specific things: prepend text, append text, and replace text in a file name. If I think of more things to do with file names in the future, I’ll update the shortcut.
