回复 7# pcl_test

谢谢，原来有这个参数，才知道，修改如下

@echo off&setlocal enabledelayedexpansion
set D=A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
for %%i in (%D%) do set #%%i=%%i
for /f "delims=" %%i in ('dir/b/l *.*') do (
	set "var=%%~ni"
	set "num=!var:~0,1!"
	if defined #!num! (
		for %%k in (!num!) do set num=!#%%k!
		ren "%%i" "!num!!var:~1!%%~xi"
	)
)
