File-systems work very well for people who understand how a computer works. And I'm afraid your right about the "apps paradigm", it looks easy within the app but the extended usage is difficult. Looking at Signal (the messenger app) on iOS we see the problems, they struggle creating save backup. The are not allowed to store the backup on the file-system only inside the app, which counteracts the idea of a backup. The other option is a cloud backup, most likely and third-party servers, which counteracts the idea of security and avability. Okay, but through some weird menus you could copy maybe something the a crippled third party app, let us say Files (not a file-browser!) from Apple. PS: I still wonder how many people could have grasp how file-systems work, if Microsoft Windows didn't provided that weird desktop metapher. Which was placed within the the "own files", which incluced the "Desktop", all accompanied by the drive letters. And UNIX? This is a tree!
