you should have a save folder in your current folder and when a new update comes out you have to download the new update and drop your current save folder into the new update folder.

Please don't do this
I have always received reports of broken saves after people attempt to transfer their save files. Save files are automatically transferred on PC/Mac.
Usually it's common sense to copy/paste a save, but your saves are already backed up with updating in mind!
It is however required to backup your save on Android as this function does not exist on Android.
