What folder are Google Podcasts downloads stored in?
data/user/0/com.google.android.googlequicksearchbox/filesvelour/feature_data/wernicke_player/downloaded_episodes



Found using the Disk Space Analyzer on my GNOME computer :-).

This is the only folder that appears in data/user/0/.

Apparently, there are a lot of other folders that might look similar, but would not be accessible by other non-system Android apps, and would not be expected to be accessible through USB either.  But my Android is quite happy for me to access this specific folder through USB.

I have enabled "Developer options", but I have not used it to change anything AFAIR.  If I disabling "Developer options", I can still plug my phone in and access the above folder using USB.
