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 osimport os.pathimport Imageimport 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 osimport os.pathimport Imageimport 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
