Tidy up my music library?

Hi, Volumio is genius, for once something that actually does work straight out and as described, no endless reboots and noodling, and if I’m not mistaken a USB drive/Pi/AUNE DAC actually sounds better than the CD player it replaced.
I’ve chosen to use MPaD on my iPad to control things and it’s a great combination but MPaDs indexing has highlighted I’ve a surprising number of folders that are empty, the Pi is on a Network with a Windows PC too, is there any way from that I can “see” the contents of the USB drive and tidy things up a bit?


Self sorted, when I made a network connection for the Pi just pointing at the IP (identified in router software0, windoze now sees this as a folder.
