The description isn't specific enough to answer, but it sounds like
maybe you want the listbox to hold a list of filenames and a Text
widget to hold the contents of the highlighted filename?

The Tkinter Text widget is a powerful widget capable of displaying
a lot more than text, it can also hold images etc.

A Listbox takes a data item and inserts it at the specified
position. The easiest being END:

L = Listbox(root, width=20)
L.pack()
for item in [1,2,3,4,5]
   L.insert(END, item)   # appends item at the end

L.insert(0, 0)  # inserts at front

That's it... not too hard is it?
