I subscribe to several podcasts, and I want to delete the ones I've listened to in the past and have recently unsubscribed to. I want to keep the occasional great podcast, however, and I've made an iTunes playlist called "Great podcasts". When I try to delete the podcast from the podcast window, I get the alert, "move to trash or keep in music folder"? I pick keep in music folder, but the episode disappears from all windows and playlists! How can I get around this - to keep my podcast folder tidy and current, but store away the good ones for later without losing them?
