apk cuz I can see what is in it and copy it. The whole reason I'm writing this is cuz I did instead of. I play Terraria on pc steam version but I mean my parents r divorced and so next week I'm w/my dad and next week with my mom and repeat 24/7 until something else planned (at my mom's rn) oh and I use a kindle Amazon fire tablet to play Terraria it was only 4.99$usd and I don't want to buy another file app thingy I use ES file explorer and can't extract files.
