In this article, we will find the file having the largest size in a given directory using Python. We will check all files in the main directory and each of its subdirectories.
Modules required:
os:
The os module in Python provides a way of using operating system dependent functionality. OS module is available with Python’s Standard Library and does not require installation.
Explanation:
- The folder path is taken as input. We then walk through the entire directory using os.walk() function.
- os.walk() returns a tuple containing the root folder name, a list of subdirectories and a list of files.
- os.stat() is used to get the status of the file and st_size attribute returns its size in bytes.
Below is the implementation.
import os # folder path input print("Enter folder path") path = os.path.abspath(input()) # for storing size of each # file size = 0 # for storing the size of # the largest file max_size = 0 # for storing the path to the # largest file max_file ="" # walking through the entire folder, # including subdirectories for folder, subfolders, files in os.walk(path): # checking the size of each file for file in files: size = os.stat(os.path.join( folder, file )).st_size # updating maximum size if size>max_size: max_size = size max_file = os.path.join( folder, file ) print("The largest file is: "+max_file) print('Size: '+str(max_size)+' bytes') |
Output:
Input:
Enter folder path
/Users/tithighosh/Downloads/wordpressOutput:
The largest file is: /Users/tithighosh/Downloads/wordpress/wp-includes/js/dist/components.js
Size: 1792316 bytesInput:
Enter folder path
/Users/tithighosh/DesktopOutput:
The largest file is: /Users/tithighosh/Desktop/new/graph theory.pdf
Size: 64061656 bytes
