How can I access to the files of a game with data? I have a game called for example "Shadow Fight 2" and I like it soundtracks, so I want to have the songs but this game has data and the songs  didn't exist in the .apk file ( I opened it with an Archive Manager ) and it downloads from Internet, so the question is how can I access to the data it has downloaded? and by the way my phone is rooted.
I am not sure for apks with obb data but for apk files without obb associated just rename apk file with .zip extension and then extract res folder you will get all resources
