[文本处理] 求批处理：依据文本空行来分割成独立带编号的.txt文件

@echo off

rem 设置源文件
set "TXT=C:\Users\CaoFei\Desktop\test.txt"
if not exist "%TXT%" echo;源文件不存在&pause&exit

set "dd=%date:~,4%%date:~5,2%%date:~8,2%"
set "n=101"

for /f "tokens=1,*delims=:" %%a in ('findstr /n ".*" "%TXT%"') do (
	set "str=%%b"
	if "%%b"=="" set/a "n+=1"
	setlocal enabledelayedexpansion
	if "%%b" neq "" echo;!str!>>"%dd%-!n:~-2!.txt"
	endlocal
)
