Hi: I downloaded Bit Torrent Sync to my Xoom Tablet and to my Galaxy S4 Phone. I only want to sync my music between the two machines. I can't find my music files on the Xoom to select them to send them to my phone. Where are they? Any other tips? Thanks from an old guy that's not very computer smart. Let me clarify this message: I do have music files. I just can't find them within the Xoom's file list as it is displayed by Bit Torrent Sync. Thanks.
