[文本处理] [已解决]批处理如何把文本文件分割成N个文本文件？

@echo off
set file="abc.txt"

for %%a in (%file%) do set "dpn=%%~dpna" & set "x=%%~xa"
set /a line=0, m=0, n=0
setlocal enabledelayedexpansion
for /f "usebackq delims=" %%a in (!file!) do (
  set /a line+=1, m=line%%2, n+=m
  if !m!==0 (set last=%%a) else (echo !last!&echo %%a)>"!dpn!__!n!!x!"
)
if !m!==0 echo !last!>"!dpn!__!n!!x!"
