This program is supported under Windows and Linux

#coding: UTF8

#批量修改一个文件下的文件后缀
 sys
os
Rename ():
    #Path = "z:\\test\\"             # Windows file directory
    Path = raw_input ("Please enter the directory you want to manipulate (format like ' z:\\test '):")
    FileList = Os.listdir (Path)
    filelist:
        olddir = Os.path.join (path,files)
         files
        #打印出老的文件夹里的目录和文件 os.path.isdir (olddir):    #判断是否是文件, is a file that skips
             Continue
filename = os.path.splitext (files) [0] #filetype        
        = os.path.splitext (Files ) [1]
        newdir = os.path.join (Path,filename + '. jpg ')    #只要修改后缀名就可以更改成任意想要的格式
        os.rename (Olddir,newdir)
Rename ()

Newdir = Os.path.join (Path,str (Random.randint (1,1000)) +filetype)    #可以修改文件名为随机名称

Is that the file already has an error, the file to be changed to the name already exists, to change a conflicting name on it.
