python 实现文件批量拷贝

场景:某个文件夹下面包含数量巨大的文件,需求需要将这些文件按组(比如5000个一组)存放到不同的目录中去。

 

# Filename: CopyFiles.py

import os

import os.path



folder_capacity = 20



def copy_files(src_dir, dest_dir):

    count = 0

    current_folder = ''

    

    for item in os.listdir(src_dir):

        abs_item = os.path.join(src_dir, item)

        if os.path.isfile(abs_item):

            count += 1

            if count%folder_capacity == 1:

                current_folder = os.path.join(dest_dir, str(count/folder_capacity))

                os.mkdir(current_folder)

            open(os.path.join(current_folder, item), 'wb').write(open(abs_item, 'rb').read())



copy_files(r'C:\\src', r'C:\\dest')
