Catalina Podcast Find Files Quick Tip
I have been in the habit of archiving several podcasts. Prior to Catalina, you could select the podcast and "Show in Finder".
In the new podcast app, that wasn't available. On top of that, the podcast file is in a Cache folder with the file name encrypted.
Some searching on the interweb produced no solution but I remembered how I could drag photos directly out of the gallery to the desktop so I tried this with the podcast.
It appears that the podcast is dragged to your desktop without changing its status in Podcasts.
