How to download all files and folder hierarchy from Jupyter Notebook?

问题

If I want to download all of the files and folder hierarchy from Jupyter Notebook as shown in the picture, do you know if there is anyway to do that by simple click other than go to every single file in every folder to open the file and click download hundreds of times?

Note: This Jupyter Notebook is created by the online course teacher, so it's not opened from my local Acaconda app but the online course webpage instead. Downloading is for future memory refreshing whenever needed.

import os
import tarfile

def recursive_files(dir_name='.', ignore=None):
    for dir_name,subdirs,files in os.walk(dir_name):
        if ignore and os.path.basename(dir_name) in ignore: 
            continue

        for file_name in files:
            if ignore and file_name in ignore:
                continue

            yield os.path.join(dir_name, file_name)

def make_tar_file(dir_name='.', tar_file_name='tarfile.tar', ignore=None):
    tar = tarfile.open(tar_file_name, 'w')

    for file_name in recursive_files(dir_name, ignore):
        tar.add(file_name)

    tar.close()


dir_name = '.'
tar_file_name = 'archive.tar'
ignore = {'.ipynb_checkpoints', '__pycache__', tar_file_name}
make_tar_file(dir_name, tar_file_name, ignore)

To use that, just create a new .ipynb notebook at the root folder, the one that you want to download. Then copy and paste the code above in the first cell and run it.

When it is done - you will see a tar file created in the same folder, which contains all the files and subfolders.

The above posted answer mostly works but its copying links instead of the files the links point to. If you add dereference=True as an argument to tarfile.open you will get the files themselves.

    tar = tarfile.open(tar_file_name, 'w', dereference=True)
