The “file system” is not new, the files app is at least a year old. What they added now was just zip support (really needed) and USB sticks (I don’t care but many love this).
Don’t listen to all the whining podcasters that claim that ipad doesn’t have a file system. The files app and its integration into many apps works amazingly well, especially in conjunction with icloud drive. And you can access the local directories, so you can put a video file in the VLC folder or a PDF in the Acrobat folder. You can of course also AirDrop to the ipad already into these apps, but if you want complete control.
