File explorer

[DPaul]

Hi,
In a win11 python 10.x environment, I can start the file explorer from within python like so:

import os
def show_explorer(path):  
    os.startfile(path)
show_explorer(os.path.abspath("c:/windows/explorer.exe"))

Almost what I want. I would like it to open on a specific directory outside python.
Why?
The setup: inside python resides a tree and each extremity is a directory.
I want to click on a tree node, automatically navigate to the directory and manipulate it. (paste a pdf, click on a pdf, view a pic...etc)
If I do this inside tKinter, I cannot manipulate the directory.
Can this be done?
thx,
Paul
