Of course you can create many sub sub sub folders withing each other. Anyone remember Dos?
Maybe I’m missing something, but in Files, I can make folders within folders. Both “On My iPhone” and “iCloud Drive". 😵

yeah - easy to do using iCloud drive - both on mac and iOS
I would think it would be on iOS but I’m having an issue I’m trying to work through.
hmm . . . I just tried and it worked fine on both iOS 12.1.14 and MAC 10.14.3
that said - I have been holding off on most recent iOS and Mojave for these kinds of reasons lol
I was going to update and test and then stopped and thought no - don't do that - lol

Haha, those folders! I did try that some time back and couldn’t do it either, I can’t remember exactly, but it was probably iOS 11 or 12.Thank you. I’m working on the main screen of an iPhone. When I pull a folder overtop another folder to merge them, the target folder just scoots away. I can’t get them to merge. iOS 12.2 on an XS Max.

Actually, those were directories in DOS. 😛Of course you can create many sub sub sub folders withing each other. Anyone remember Dos?
