有一段脚本，只能看懂一点点，上网查有些说的不明不白，求翻译一下

@echo off
set b=%data:~0,4%%data:~5,2%%data:~8,2%

setlocal enabledelayedexpansion
for /d %%i in (源路径) do (
set n=%%i
set name=%%~ni
set a!=name!
set d=%%~fi
set c=!a:~0,8!


 if "!c!"=="%b%" (
set DataPath=!n!\
set DestPath=D:\TEST\
set DataExt=*.文件格式
set w=\文件格式\
set rar=rar.exe
set rarname=!a!.rar

 
set ftpserver=地址
set user=用户名
set pass=密码
set ftppath=目的路径
set Ftp=目的路径/!a!

@echo open !ftpserver!>ftpcmd3
