List every files of every folder of every share

I saw the commands for listing files and share in the Repo's home page, but i noticed that the way for locating a folder is still "static" <<correct me if I'm wrong>> (with the dir("/path"); method). How can i list every folder with all of its file/subfolder and print their name with their size?

p.s. i mean recursively, to have a "real time" listing
