Hello, on the Mac, we can store user files on the deskstop or within most folders. How about the iPad? I am confused about where user files are stored. As I read, in the past they are stored within each individual app. However, perhaps in iOS 11, things are different? I have a pdf file in dropbox. I tried to download it to the iPad but I cannot find the file on the iPad desktop. Could you please let me know where it is stored? Perhaps some kind of Download folder? Also, could you please recommend apps that allow me to view different folders on the iPad/iCloud/Dropbox, copy/move files to different locations, rename, etc.? Thanks.
