File manager with an ncurses frontend written in Python

 Ranger is a free console file manager that gives you greater flexibility and a

 visualizes the directory tree in two dimensions: the directory hierarchy on
 one, lists of files on the other, with a preview to the right so you know

 The program is written in Python and uses curses for the text-based user
