if you already have a file named arch00.zip and arch01.zip, we have to do something with the arch00.zip file first if you want to rename arch01.zip to arch00.zip.

this will rename this file arch00.zip to arch00_1.zip and then rename the others
I Didn't test it so make sure u test it in a copy of your files first
Code: Select all
@echo off
cls
Mode 50,10
setlocal enabledelayedexpansion
IF exist "arch00.zip" Ren "arch00.zip" "arch00_1.zip"
For /R %%z in (*.zip) Do (
set file=%%~nz
For /F "tokens=*" %%a in ("!file:~5!") Do (
set num=%%a
set /a Nnum = num - 1
Ren "%%~nz.zip" "arch0!Nnum!.zip1" >nul
)
) >nul
Ren "*.zip1" "*.zip" >nul
Exit /B

I was trying to think what the user was possibly thinking and I assumed that the file names were also greater than 09 (arch10 arch11 etc). I didn't recurse the directory tree like abc0502 did. This would only work on a single folder and I don't have anything to take care of the initial 00 file but you could just use the same code abc0502 did to test for the existance of the 00 file and rename it.
Code: Select all
@echo off
setlocal enabledelayedexpansion
for %%G in (arch*.zip) do (
set num=
set base1=%~nG
set base2=!base1:~0,-2!
set ext=%~xG
IF "!base1:~-2,1!"=="0" (
set num=!base1:~-1!
) else (
set num=!base1:~-2!
)
set /a num=!num! - 1
IF !num! LSS 10 (
rename "%%G" "!base2!0!num!!ext!"
) else (
rename "%%G" "!base2!!num!!ext!"
)

You did code per the example. I was just thinking out of the box. I should stop thinking!

Infact you shouldn't, making a batch that work in general to work on any case is always better
