this is around 50% of the space used by the apps!!!!
Where are these 15.5 Gb? How are they used?
I am sure I had 7.5 Gb before the update of Space Pirate Trainer to Space Pirate Trainer DX, but I don't think the app size increased of more than 0.3 Gb. So why did it take additional 1.7 Gb from my Oculus???
Can I convert this missing space to free space again? how?
