Phones just don't make a good analog to computers with a robust file system browser. My experience is if you're downloading something on a phone, it's never going be used again. It will sit there until a factory reset.
How many restaurant menus have I downloaded read once and never cleared off? I don't know. I also don't care. If I did care, I would want to use "Save As..." and save to google drive.
