09 Sep, 2021
Kivy is a platform independent GUI tool in Python. As it can be run on Android, IOS, linux, and Windows, etc. It is basically used to develop the Android application, but it does not mean that it can not be used on Desktops applications.
Kivy Tutorial – Learn Kivy with Examples.
The FileChooser module provides various classes for describing, displaying, and browsing file systems. It is Simple like the My computer from where we can choose any file in the system.  
The FileChooserListView displays file entries as text items in a vertical list, where folders can be collapsed and expanded.
The FileChooserIconView presents icons and text from left to right, wrapping them as required.
Note: The both above points provide for scrolling, selection and basic user interaction. 
Basic Approach 
1) import kivy
2) import kivyApp
3) import Boxlayot
4) Set minimum version(optional)
5) create layout class
6) create App class
7) create .kv file
8) return Layout/widget/Class(according to requirement)
9) Run an instance of the class or App
Implementation of the Approach:.py file 
Python3
# Program to explain how to use File chooser in kivy        # import kivy module    import kivy           # base Class of your App inherits from the App class.    # app:always refers to the instance of your application   from kivy.app import App        # this restrict the kivy version i.e  # below this kivy version you cannot  # use the app or software  kivy.require('1.9.0')  # BoxLayout arranges widgets in either in# a vertical fashion that is one on top of# another or in a horizontal fashion# that is one after another.from kivy.uix.boxlayout import BoxLayout # create the layout classclass Filechooser(BoxLayout):    def select(self, *args):        try: self.label.text = args[1][0]        except: pass # Create the App classclass FileApp(App):    def build(self):        return Filechooser() # run the Appif __name__ == '__main__':    FileApp().run()
.kv file 
Python3
#, kv file implementation <Filechooser>:         label: label     # Providing the orientation    orientation: 'vertical'     # Creating the File list / icon view         BoxLayout:         # Creating list view one side        FileChooserListView:            canvas.before:                Color:                    rgb: .4, .5, .5                Rectangle:                    pos: self.pos                    size: self.size            on_selection: root.select(*args)         # Creating Icon view other side        FileChooserIconView:            canvas.before:                Color:                    rgb: .5, .4, .5                Rectangle:                    pos: self.pos                    size: self.size            on_selection: root.select(*args)     # Adding label    Label:        id: label        size_hint_y: .1        canvas.before:            Color:                rgb: .5, .5, .4            Rectangle:                pos: self.pos                size: self.size
