I can no longer download apps or reply to emails from my phone. I get a "not enough storage space so this feature has been disabled" message. How can clear out large amounts (entire folders) of data? I don't want to open each item and delete on at a time. For example, there is nothing in my "downloads" folder that I need, so I don't want to back it up to the Cloud, I just want to delete all the items. Please help!
