Well, an SD card isn't meant to hold things like apps, which for some reason people assume adding a card will add to their phones "Internal" storage automatically. Which just isn't the case. To have photos, music, videos, etc. (not apps) save automatically to the card you would need to change the settings for the apps you are using for creating the music, videos, etc., and set it to save new ones to the SD card. You would also need to either move files individually, or move them over to a computer (all at once) and then move them all back to the SD card. Again, not talking apps. Apps is a different thing. It requires that the SD card be able to be turning into "Internal" storage rather than "External" storage, which not all manufactures...
