Create subfolders on iPhone/iPad

I’m currently watching some tutorial videos for work, and they’re located in FILE A and inside that is FILE B. It would be a great feature if I could organise using multiple file structures rather than just the one from the main screen. It’s fine for movies, but would also like a folder called “TV Shows” with them organised in individual sub folders inside.

Would love to see this feature! Currently I use this on my iPad if it matters! Thanks :slight_smile:
