Just started to test Pi MusicBox however I end up with several problem.

  1. used MicroSD 64GB however the space is out. Trying to resize but I cant seems to get the info. Anyone can help me out?

  2. Connecting using SSH allow me to see the directory. However I can seem to get where can I upload my mp3 files? Should I put it in /music?

Thanks
