minecraft world backup
hi
my son uses Minecraft PE on my iPad and has created lots of worlds. I need to restore the iPad to factory settings and want to know whether I will lose all those worlds if I do so. I have backed the iPad up to my iMac using iTunes but am not sure if a restore from tat backup will restore the worlds or just the app (empty)?
I checked the web and it seems that since iOS 8.3 all the 3rd party file explorer apps that might have allowed me to access and backup the "worlds" files on the iPad can no longer do this. Is there any way to back up these files in iOS8.3?
I am not too technical, so help in simple english would be much appreciated! Thanks!
iPad 2, iOS 8.3, 16gb
