If like me you want a more hands-on approach to file manipulation on your iPad here's a way that works. Now I am not a Windows fan (to put it mildly) so if you're not a unix person this info is probably not for you. My OS of choice is the latest version of Linux Mint (17.3). This is open source and free and has a huge amount of support especially on the many forums. The method of file handling I use is SSH and rather than use the command line I use an application called "secpanel" which gives the SSH a graphical-user-interface (GUI). It can be installed using "sudo apt install secpanel". Let's say you've got this done (skipping a lot of instructions here that you can Google for). The directory path to the applications storage directories is this: /private/var/mobile/Containers/Data/Application/. That last sentence is Very important and the main reason I am posting this. Let me also say that to get "under the hood" I've rooted the iPad and the how-to is also easily Google-gotten. Need help? Please feel free to post or message me.
