I seem to have close to filled my internal storage, while I have a nearly empty SD card.
It's easy enough to move photos & videos, and set the SD card as the default.
But... I seem to have 11g of music & audio files - they show up in the "MyFiles app" - but there doesn't seem to be a "move to SD card" option - either in MyFiles, or for any of the audio apps on my Note 8 (Samsung Music, Spotify, Double Twist) - they all show storage (under the apps settings) - but don't give a move to SD option.
Solved! Go to Solution.
open you file manager and goto internal memory locate your audio files and move them to your memory card.
Found my own answer - no thanks to Verizon, Samsung, or community support.
A little app, in the Google App Store, called "Files To S Card."
