用vbs会简单一些，bat会很累赘，楼主把old.txt改成你的文件名就可以了

@ECHO OFF
Setlocal enableDelayedExpansion
for /l %%i in (0,1,62) do (
	set /a count1=%%i+1&set count1=00!count1!&set count1=!count1:~-2!
	set str1=&set count=
	for /f "tokens=1,2" %%j in (old.txt) do (
		set str=%%k&set str=!str:~%%i,1!
		set str1=!str1! !str!&set /a count+=1
		if !count! geq 3 echo %%j !str1:~-5!>>!count1!.txt
	)
)
