codingdirectional: Search for any duplicate file with python

Welcome to the new chapter of this remove duplicate file project. After creating a thread class, open a file and open a folder in the previous few chapters, we can now start to move toward our main objective which is to search for a duplicate file in another folder.

What we will do in this chapter is to write a program to select a file and select a folder which we want to look for the file with the same filename as the one which we have just selected earlier. If the file with the same name does exists in another folder then we will print the file found statement on the application’s label or else we will print out no file with the same name found statement on that same application’s label.

Lets get started. First of all we will edit the main program file to select a file and the folder, the open folder dialog will only open if and only if a file has been selected.

from tkinter import *
from tkinter import filedialog
from Remove import Remove

win = Tk() # 1 Create instance
win.title("Multitas") # 2 Add a title
win.resizable(0, 0) # 3 Disable resizing the GUI
win.configure(background='black') # 4 change background color

# 5 Create a label
aLabel = Label(win, text="Remove duplicate file", anchor="center")
aLabel.grid(column=0, row=1)
aLabel.configure(foreground="white")
aLabel.configure(background="black")

# 6 Create a selectFile function to be used by button
def selectFile():

    filename = filedialog.askopenfilename(initialdir="/", title="Select file")
    if(filename != ''):
        filename = filename.split('/')[-1] # this is for the windows separator only
        folder = filedialog.askdirectory() # 7 open a folder then create and start a new thread to print those filenames from the selected folder
        remove = Remove(folder, aLabel, filename)
        remove.start()

# 8 Adding a Button
action = Button(win, text="Open Folder", command=selectFile)
action.grid(column=0, row=0) # 9 Position the button
action.configure(background='brown')
action.configure(foreground='white')

win.mainloop()  # 10 start GUI

Now we will modify our Remove thread class to search for a file inside another folder.

import threading
import os

class Remove(threading.Thread):

   def __init__(self, massage, aLabel, filename):

      threading.Thread.__init__(self)
      self.massage = massage
      self.label = aLabel
      self.filename = filename

   def run(self):
      text_filename = 'There is no duplicate item'
      filepaths = os.listdir(self.massage)
      for filepath in filepaths:
         if(filepath == self.filename):
            text_filename = 'Found duplicate item'
      self.label.config(text=text_filename)
      return

If you run the above program you will see this statement appears if the duplicate file has been found!

Found the duplicate item

In the next chapter we will start to remove the duplicate file from another folder!
