I just acquired 500+ 2-hour long radio shows, which even as MP3s is too much for my internal storage. I have the originals on my external drive as backups, but I don't want to keep the library copies on the same drive, for obvious reasons. I have an SD card that I wanted to use as expanded storage for my library, but MusicBee will only recognize it as a portable device. I've manually moved the files for now, but I would prefer to keep them auto-organized and MusicBee won't let me.
