Hello, I have an Asus vivotab surface rt 8.3. I bought it about 2 years ago . It seemed like a steal for a high quality tablet. While I did not thoroughly research the tablet, I was aware that the OS was a very compromised version of windows and that MS had pulled the plug on the OS. I'd have to say that even though I paid next to nothing for the tablet, about $ 140, I am appalled by the lack of support from MS. On MS sites finding information and help with usage is limited and very hard to find. Thus, I arrive on this forum. Sadly, the number of RT users seems to be fading away. I don't use my RT much. It's too hobbled by the OS and I have android tabs that are easier and contempory. So I have decided to try to use theRT as a media player. It would be connected to my stereo/home theater receiver using the microphone jack and I would like to play back music files from my personal collection, ripped from cds. I have run into several problems in getting mp3 files from my Win 10 desktop to Win RT. The first is how to get them onto the RT. Specifically, I want to get them onto a 64 GB sd card and then to the RT. The second problem is that the files are MP3 format and it's not clear if they can play on the RT and be played from the SD card. I can, of course convert the music files to wmv format on the dektop and then move them to the sd card, insert the sd card into the RT. I would hope that RT would play WMV files, but I take nothing for granted with RT. I hope to get some ideas about uses for the RT. It is a solid tablet, with an excellent screen, but it's so difficult to utilize and trouble shoot.
