前天不小心把硬盘格式化了，丢了好多照片，后来用Recuva这款软件成功把文件恢复过来，可是恢复的文件中有好多重复的文件和无法打开的图片，所以写了两个python的小程序用来解决这个问题

删除相同文件：

#coding=utf-8

import os

import os.path

import Image

import hashlib

def get_md5(filename):

m = hashlib.md5()

mfile = open(filename, "rb")

m.update(mfile.read())

mfile.close()

md5_value = m.hexdigest()

return md5_value

if __name__ == '__main__':

ipath = "E:\\20161019_photo"

uipath = unicode(ipath, "utf8")

for parent, dirnames, filenames in os.walk(uipath):

md5_list = []

#for dirname in dirnames: # 输出文件夹信息

#print "parent is:" + parent

#print "dirname is: " + dirname

for filename in filenames:

#print "parent is :" + parent

#print "filename is:" + filename

#print "md5_list is : "

if(get_md5(os.path.join(parent, filename)) in md5_list):

os.remove(os.path.join(parent, filename))

else:

md5_list.append(get_md5(os.path.join(parent, filename)))

#print md5_list

#md5 = []

删除无法打开文件：

#coding=utf-8

import os

import os.path

import Image

import hashlib

def get_md5(filename):

m = hashlib.md5()

mfile = open(filename, "rb")

m.update(mfile.read())

mfile.close()

md5_value = m.hexdigest()

return md5_value

if __name__ == '__main__':

ipath = "E:\\20161019_photo"

uipath = unicode(ipath, "utf8")

for parent, dirnames, filenames in os.walk(uipath):

for filename in filenames:

name ,ext = os.path.splitext(filename)

if((ext == ".png") or (ext == ".tif") or (ext == ".gif")):

os.remove(os.path.join(parent, filename))

else:

if(ext == ".jpg"):

try:

fp = open(os.path.join(parent, filename), 'rb')

img = Image.open(fp)

except:

fp.close()

os.remove(os.path.join(parent, filename))

else:

continue
