-Ttk is the new Tk themed widget set. \
-One of the widgets it includes is a tree widget, \
-which allows the user to browse a hierarchical data-set such as a filesystem. \
-The tree widget not only allows for the tree part itself, \
-but it also supports an arbitrary number of additional columns \
-which can show additional data (in this case, the size of the files \
-found in your filesystem). \
-You can also change the width of the columns \
-by dragging the boundary between them.
