用Python查询目录文件大小

查看自己电脑硬盘的文件占用情况

问题：想删除C盘的一些内容，又不知道哪些文件占用的，就自己写了个，查询内容存在csv里，自己排序看看，简单粗暴

import os
from os.path import join, getsize

def getdirsize(dir):
    for root, dirs, files in os.walk(dir):
        try:
            for name in files:
                filename = join(root, name)
                size = getsize(filename )
                print('There are {:.3f} Mbytes in {}'.format(size/1024/1024,filename))
                with open(r'size.csv','a+') as f:
                    f.write('{:.3f},{}\n'.format(size/1024/1024,filename))
        except WindowsError:
            pass

if __name__ == '__main__':
    getdirsize(r'c:\\')
