I'm sorry if this has been answered before, but I searched the boards and couldn't find the answer. I just got my tablet for $185 at walmart and I got a 32gb microsd card too. I put the card in the tablet, connected the tablet to my pc. I can see the microsd card when I explore the tablet from my pc. I went ahead and dragged and dropped a 300mb video to the microsd card. I disconnected the tablet. Now, how do I play the video? More importantly, how do I explore the microsd from the tablet? I can't find any like "my computer" or "explore" to be able to find the microsd card, the files on the card, or tap and open the video file. am I missing something? Is there some additional app I have to download to be able to access something on the card?
