I’m trying export a playlist to a usb, copying the tracks from my external HD. Some tracks just won’t copy. I’ve checked consistency, removed all missing tracks from my collection , I’ve loaded each track from the playlist into the player so I know they’re not missing. The usb shows folders for all tracks in the playlist, the folder for the missing tracks are empty, adding the track to that folder doesn’t bring it into the playlist. Any ideas? Playing on someone else laptop shouldn’t be this hard!
