i want a skin for minecraft PE but i don't want to get rid of all my worlds by deleting it is there another way or perhaps a way to get my worlds back after i deleted it help would be very much appreciated
Unfortunately, you can't reclaim worlds that have been deleted from your device.
However, if you want to edit something in the game, but don't want to lose your maps, you can export the maps to a computer before you edit your game. Then once you've edited it, you can move the map back to your device from your computer.
Now I haven't tinkered with maps for a while now, so I don't know if this is still how it's done, but for iOS I used iExplorer to extract map files from my iOS device. With Android I just used a file manager app, found the map files, and emailed them to myself.
Again, I'm not sure if that's still how it's done... Can anyone confirm this?
