On a backup SD card. Changed the name of existing folder (changed in csv file… changing Country to My Folder). Copied songs from Blues, Rock and POP that I often use into the renamed My Folder. Change the csv file in the My Folder to add what ever you copied there. Now I have little need to jump folders which is great when you begin associate beats with the songs you do.
I was just about to try that - glad I was on the right track and can look forward to success!
