OK! ! ! so i'm seriously ignorant regarding this tech stuff ! ! ! what i really want to be able to do is to aquire the ability to choose where i save files generated on my tab:ie on the external sd card. i don't want to have to download stuff from a computer to be able to access it. also, in order to use docs 2 go desktop i have to be able to pair my device with my windows 7 pc. and apparently this requires the option of utilizing UMS rather than MTP/PTP . HAS ANYONE FIGURED OUT HOW TO ACCOMPLISH THESE TWO THINGS? I WOULD GREATLY APPRECIATE SOME HELP (clearly explained for this newby) am i asking too much from this unit? thanks in advance for your time and patience with me.
