当前文件夹下，把所有文件名中的“50076“替换成”50092“，用Python实现，代码所下：

# encoding: utf-8

import os

import os.path  

curDir = os.getcwd()

oldId = "50076"

newId = "50092"

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

    for filename in filenames:

        if filename.find(oldId)!=-1:

            newName = filename.replace(oldId, newId)

            print(filename, "---->", newName)

            os.rename(os.path.join(parent, filename), os.path.join(parent, newName))  

os.system("pause")

附：遍历特定文件夹中的文件以及子文件夹，代码如下：

# encoding: utf-8

import os

import os.path

rootdir = r'D:\game'    # 指明被遍历的文件夹  

#三个参数：分别返回1.父目录 2.所有文件夹名字（不含路径） 3.所有文件名字

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

    for dirname in dirnames:    #输出文件夹信息

        print "parent is: " + parent

        print "dirname is: " + dirname  

    for filename in filenames:  #输出文件信息

        print "parent is: " + parent

        print "filename is: " + filename

        print "the full name of the file is: " + os.path.join(parent,filename) #输出文件路径信息
