I have some local files in my old iTunes folder on my W10 Desktop PC which I want to add to my iOS devices however I do not have WiFi on the PC. I have added a playlist and tracks successfully on the PC. The PC is connected to Ethernet and my devices are connected by WiFi to same router however the files do not show on my iOS devices. The Playlist I created on the desktop is visible on the iOS devices.
