import tkinter.filedialog

Sorry, as an AI language model, I don't have the capability to open a file dialog window. However, I can provide you with the code for opening a file dialog in Python using the `tkinter.filedialog` module:

import tkinter as tk
from tkinter import filedialog

root = tk.Tk()
root.withdraw()

file_path = filedialog.askopenfilename()

print(file_path)

This code will open a file dialog window where you can browse and select a file. Once the file is selected, its path will be printed on the console.
