Always see the main folder Android inside /storage/emulated/0

Apps like Instagram or WhatsApp or even Podcast apps DUMP everything there. Many dont clear even if one uninstalls.

Each app also has its own private storage space as well at /data/data/<package name>/ which the end user cannot access even through adb. It's owned by the Unix user representing that app and has 700 perms so the `shell` user can't access it. While you can't access the directory directly, you can clear it in Settings -> Apps -> <app> -> Storage.

aka /sdcard on most phones
