CodePudding user response：

You just get the selected item iid inside Open_file_from_list_box():

def Open_file_from_list_box(value):
    global file
    file = tree.selection() # return item iid, not the file name
    ...

It should be:

def Open_file_from_list_box(value):
    global file
    item_id = tree.selection()
    file = tree.item(item_id, 'text') # get the filename from 'text' option
    ...
