解决方法是：

1. 找到你想下载的文件夹

2. 打开文件夹，新建一个ipynb

3. 粘贴下面代码并运行

4. 回到文件夹，刷新，看到多了个archive.tar的压缩文件，下载这个文件解压就行。

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)
