Alexander_88,

вариант (на всякий случай) для NNNNstart

Код:

@Echo Off
cls
>nul Chcp 1251
 
	Set "BoxIn=Z:\Soft_In"
	Set "Kword=start"
rem	Set "Reg=^%Kword%[0-9][0-9][0-9][0-9]\..*"
	Set "Reg=^[0-9][0-9][0-9][0-9]%Kword%\..*"
	Set /A M=4

	Set "Mask=*.*"
	Set /A Max=2

	Set /A NMax=0	
rem	FOR /F "usebackq delims=" %%a IN (`2^>nul Dir "%BoxIn%\%Kword%*.*" /B /O:N /A:-D ^|findstr /I /R /C:"%Reg%"`) DO (
	FOR /F "usebackq delims=" %%a IN (`2^>nul Dir "%BoxIn%\*%Kword%.*" /B /O:N /A:-D ^|findstr /I /R /C:"%Reg%"`) DO (
		Set "NMax=%%~na"
rem		Call Set "NMax=1%%NMax:~-%M%%%"
		Call Set "NMax=1%%NMax:~0,%M%%%"
	)

	Set /A Num=1000000
	Set /A Num=%Num%+%NMax% 
	Set /A MMax=%Max%+%Num%

	Set /A MMax=%Max%+%Num%
	FOR /F "usebackq delims=" %%a IN (`2^>nul Dir "%BoxIn%\%Mask%" /B /O:N /A:-D ^|findstr /I /R /V /C:"%Reg%"`) DO (
		Call :RenNNN "%BoxIn%" "%%a" "%Kword%" %M% %MMax% ||Exit /B 1 
	)
Pause
Exit /B

:RenNNN
	Set /A Num+=1
	If %Num% GTR %5 Exit /B 1 
	Call Set "NNum=%%Num:~-%4%%"
rem	2>nul Ren "%~1\%~2" "%~3%NNum%%~x2" ||GoTo :RenNNN
	2>nul Ren "%~1\%~2" "%NNum%%~3%~x2" ||GoTo :RenNNN
Exit /B 0

Спасибо, удалил красные строки, теперь все работает для NNNNstart
