Quest 2 file system: Oculus saved/cached media files

Good morning!

I've cached/saved about 25 Oculus TV media files on my headset for the higher resolution and no load waits.

Using SideQuest or browsing the Android file system directly, I can't find where those media files are stored.

I've looked in every single folder. Are saved media files hidden somehow for security? Just where are saved/cached media files located? 

This has been driving me crazy for weeks. I would appreciate any pointers or tip from our wizard crew.

Thank you!
