List Top File-size Files

This Python script is designed to list the top files by size on a file drive (under Windows-OS), as determined by the user.

Requirements

In order to use this script, you must have Python 3 installed on your system. You will also need to have the os and sys modules installed.

	import os
	# ask user for device id and number of files to list
	while True:
	device_id = input("Enter the device id (e.g. C:): ")
	if os.path.isdir(device_id):
	break
	print("Invalid device id. Please enter a valid device id.")
	while True:
	num_files_str = input("Enter the number of files to list: ")
	if not num_files_str.isdigit():
	print("Invalid input. Please enter a positive integer.")
	continue
	num_files = int(num_files_str)
	if num_files > 0:
	break
	print("Invalid input. Please enter a positive integer.")
	# get list of files on device and sort by size
	file_list = []
	for root, dirs, files in os.walk(device_id):
	for name in files:
	try:
	file_size = os.path.getsize(os.path.join(root, name))
	file_list.append((os.path.join(root, name), file_size))
	except:
	# ignore file if it cannot be accessed
	pass
	file_list.sort(key=lambda x: x[1], reverse=True)
	# print top n files and ask user to select a file to open
	while True:
	print("\nSelect a file to open:")
	for i in range(num_files):
	if i >= len(file_list):
	break
	file_path = file_list[i][0]
	file_size = file_list[i][1]
	print(f"{i+1}. {file_path} ({file_size} bytes)")
	print("0. Exit")
	# ask user to enter the index of the file to open
	while True:
	file_index_str = input("Enter the index of the file to open: ")
	if not file_index_str.isdigit():
	print("Invalid input. Please enter a positive integer.")
	continue
	file_index = int(file_index_str)
	if 0 <= file_index <= num_files:
	break
	print(f"Invalid input. Please enter a number between 0 and {num_files}.")
	# exit if user enters 0
	if file_index == 0:
	break
	# open explorer window for the selected file
	file_path = file_list[file_index-1][0]
	os.startfile(os.path.dirname(file_path))

Usage

1. Run the script from the command line using python listTopFilesizedFiles.py.
2. Enter the path of the drive you would like to search when prompted.
3. Enter the number of files you would like to see listed when prompted.
4. Choose an action from the menu that appears:
   • Enter a file number to open that file’s location in Windows Explorer
   • Enter 0 to exit the program
   • Enter r to run the script again from the beginning
5. If you choose to open a file location, a Windows Explorer window will open to the directory containing the selected file.
6. If you choose to exit the program, the script will end.
7. If you choose to run the script again, you will be prompted to enter a new drive path and number of files to list.
