Python comes with a standard module called os that is used to handle file management using Python. With the help of Python
modules, we can perform many file management tasks like creating, renaming, moving, copying, searching, and deleting files and directories. If you want to know more about Python file management with the
In this tutorial, we will not be covering all the important methods of the
module. Instead, we will be using it to find specific extension files from a directory. For example, we will be writing a python script that can find all the .txt, .doc, .py, .jgeg, etc., files from a specific directory.
Python program to find all the
files from a directory
We will start with finding all the
files present in a specific directory. For this tutorial, I will be searching all the
files present in the same directory where my Python script is located and printing the complete path as an output.
import os for file in os.listdir(): if file.endswith(".txt"): print(os.path.join(os.getcwd(),file))
C:\Users\tsmehra\Desktop\code\data.txt C:\Users\tsmehra\Desktop\code\external_css.txt C:\Users\tsmehra\Desktop\code\external_script.txt C:\Users\tsmehra\Desktop\code\passwords_list.txt C:\Users\tsmehra\Desktop\code\vulnarable_banners.txt
function will return a list of all the files and directories present in the current directory. The
is a Python string function that will check if a file ends with an extension of
function returns the absolute path of the current working directory. The
method will join the current working directory path with the file name. In the above example, I have listed all the .txt files that are present in the same directory where the Python script is located. If you want to find files of different directories there you need to change the working directory by using the
import os directory = r'C:\Users\tsmehra\Documents' os.chdir(directory) #change the current working directory for file in os.listdir(): if file.endswith(".txt"): print(os.path.join(os.getcwd(),file))
C:\Users\tsmehra\Documents\allnew.txt C:\Users\tsmehra\Documents\config.txt C:\Users\tsmehra\Documents\Python has many built.txt
It's very important to use the
prefix before the directory name else we need to specify the escape characters.
Python program to find all the Python
files from a directory
The program will remain the same. The only change we need to make in order to retrieve all the
files is in the
import os #directory = r'<mention directory path>' #os.chdir(directory) #change the current working directory for file in os.listdir(): if file.endswith(".py"): #only python .py files print(os.path.join(os.getcwd(),file))
C:\Users\tsmehra\Desktop\code\assambaly.py C:\Users\tsmehra\Desktop\code\attack.py C:\Users\tsmehra\Desktop\code\checkweather.py C:\Users\tsmehra\Desktop\code\client.py C:\Users\tsmehra\Desktop\code\colorful.py C:\Users\tsmehra\Desktop\code\compareimage.py C:\Users\tsmehra\Desktop\code\contours.py C:\Users\tsmehra\Desktop\code\crackpassword.py C:\Users\tsmehra\Desktop\code\CssJSlinks.py C:\Users\tsmehra\Desktop\code\dDosattqack.py C:\Users\tsmehra\Desktop\code\deconde.py C:\Users\tsmehra\Desktop\code\DecryptFile.py .........
Python program to find all the Images
.jpeg, .jpg, .png
files from a directory
Now let's find all the images present in a specific directory. The code will remain pretty the same as we have written for the above examples, but here will be making some changes in the conditional if statement.
import os directory = r'C:\Users\tsmehra\Pictures' os.chdir(directory) #change the current working directory to pictures for file in os.listdir(): if file.split(".")[-1].lower() in ["apng", "avif", "gif","jpeg", "jpg", "png", "svg"]: print(os.path.join(os.getcwd(),file))

Let's sum up the above Python tutorial. In this tutorial, you learned how to find specific file extensions in Python. The module we used in our tutorial is
which is a Python standard module for file and directory management. If you are searching for the files that are present in the same directory of your Python script, then you do not need to change the working directory, but if you wish to find files from another directory there, you need to change the working directory using the
will list out all the directories and files present in the current working directory, and using the if statement and endswith() statement we can find the specific extension files.
