python list files and folder using tkinter

[Pascal B]

Hello,
I have already posted a message some time ago for this app. Since then, I didn't code in python or made any changes. I think before getting further with functionnalities a few things or the whole thing need to be changed.
For exemple, it would need a button to pick folders and maybe ask if the csv resulting file can be saved in the same folder.
And more important, files are listing ok in windows but not in linux after running it a few times.
