This question is pretty much the same as How can I redownload an episode of podcast which I accidentaly deleted?. That old question had an answer, although a comment says the answer is no longer relevant to later versions of iTunes. I'm not sure what the protocol is for this situation, but since I have the same problem today I thought I'd re-ask the question.
I am running iTunes v220.127.116.11 on Windows 7. I needed to reclaim some disk space so I manually deleted some of the downloaded podcast files from the iTunes folders.
How can I redownload that file via iTunes when I wish to listen to it again? The Podcast listing indicates that that file is already downloaded (i.e. there is no cloud icon to click on to initiate a download)
