一个批处理,可以方便的备份桌面上的文件.

代码:

@echo off
mode con cols=78 lines=10&color b0
setlocal enabledelayedexpansion
Title 载入中...


::备份文件次数,超过此次数，依次向前替换上一次备份
set strBakCount=10
::目的确路径
set strBakPath=BakFile
::备份路径
set strFo=%userprofile%桌面
::备份类型
set strOP=txt doc xls pdf lnk
::执行命令
set strRunName=桌面文档备份


::备份文件夹初始化
