Hi Shad0wX, congratulations on your new Eken tablet and welcome to the forum. Nice of you to become a member of Android Tablets. You can't set the SD Card as the default storage. The External Micro SD Card (MSD) AKA TF Card is and always was intended as space to store your media files. Using a file explorer program, you can move all of your books, pictures, videos, movies, music files etc. there. There are lots of free explorers available if the one that came with your tablet can't handle it. Astro File Manager and ES File Explorer are both pretty good and there are free versions on the Market.
