Where do I find downloaded files on my iPhone? I want to find the documents I downloaded from Scribd app. I have iPhone 6 Plus

Hard to be specific but I would think you need to start looking in the various Apps on your device that can manage, view or edit such downloads, so the first place would be “Files” or “Books”. I also have an app call “Documents” that when downloading a pdf via Safari gets placed inside it, so unless you can remember the download destination it’s a bit trial and error as you work your way through each in turn.

You could also try the Search option by pulling down midway on the Home screen and typing the file name (if you can remember it) in the search box, it should work.

ps. The first place to start looking is in the Scribd app itself, also this may help because I believe not all content can be downloaded.
