The path to the music folder with escape characters like you said is:
/media/EXTERNAL HD/Local Disk (F)/My Music/
I just set permissions to 755. The drive is vfat though…
After changing the music location to what I have above (which I tried before) and changing the permissions it still doesn’t work. When I click “Start Scan” it scans for all of 5 seconds and then is finished without detecting any music.
