Python: How to choose file with a GUI but prevent browsing to other directories?

I would like to let user delete files from a specific directory. Thus I use:

from Tkinter import Tk
from tkFileDialog import askopenfilename

Tk().withdraw()
filename = askopenfilename()

It opens a file browser and user selects a file. But user can browse to other directories in this GUI window.

I want to prevent user to browse to other directories, so that he/she won't be able to delete files from other folders. User should only be allowed to choose files from that starting directory.

How to do this?

I think you'll be stuck subclassing the standard dialogs for a UI way to do it. However, for the quick and dirty it should be possible to use askopenfilename() in a loop. Something along the following:

while True:
    filename = askopenfilename()
    if not filename:
        raise FileDeleteAbortError()
    if os.path.dirname(filename) == expected_directory:
        break
    tkMessageBox.showwarning() # pick another file, this one's in the wrong directory

I don't think this is possible with the standard file dialogs. But you could write your own. Just use a treeview widget to display all files (and relevant information) in the directory. The User can multi select the files and you can delete them after the user dismisses the dialog.
