How can I put a podcast on my USB device?
Solution 1:
Podcasts stores downloaded files at this location in Finder:
~/Library/Group Containers/243LU875E5.groups.com.apple.podcasts/Library/Cache
(You can access this by using "Go to Folder" option in Finder, which is Command+Shift+G)
Unfortunately, these episodes are not labeled with the episode name. If you open the file in VLC, however, the embedded data will be visible. Once you find the file you'd like, you can copy it to any location you'd like.
