Copying a folder to another disk in python

Question

I have made this code to copy a folder to another disk, and it works, but I think there is a better way.

If don't use the replace(), it says the folder exists and it is correct. The 'T': is real. Can someone point me to the right path?

The folder_path is the path for the torrent folder. it is a normal path, like: 'D:/FILES/MYFOLDER'. The file_path is a variable as to make a torrent, if a folder=folder_path, if a file=file_path, but its not important for the question.

folder_path = 'D:/FILES/MYFOLDER'
file_path = ''

src = folder_path
folder_path_copy = folder_path.replace('D:/FILES/', '')
destination = 'T:' + folder_path_copy
logging.info('Copying files')

if file_path == '':
    shutil.copytree(src, destination)
    logging.info('Folder copied')
else:
    pass

Answer 1

We can simply copy any folder to any disk by using shutil.copytree() function. I think the name you are using to copy your folder to disk T already exist. So check that. I copied one of my folder from disk C to disk D with following lines of code without using replace() function. Here's the code:

import shutil

# your source and destination path could be different

src = 'C:\\Users\\Lenovo\\PycharmProjects\\practice\\invitations'
destination = 'D:\\invitations'
shutil.copytree(src, destination)

The above code successfully copies the invitations folder in disk D.

1. Your code is broken, since it has uninitialized variables.
2. Your empty else block is redundant and can be removed.
3. You can use pathlib to calculate the relative paths.

from logging import info
from pathlib import Path
from shutil import copytree

src_dir = Path(r'D:\FILES\my_folder')
relpath = src_dir.relative_to(r'D:\FILES')
dest_dir = Path('T:') / relpath
info('Copying files')
copytree(src_dir, dest_dir)
logging.info('Folder copied')
