how to automatic. rename many txt files?
this
john - 1
john - 2
john - 3
john - 4
john - 5
john - 6

i WANT to change them to this, i have 1200 so is hard to do that manually:

john1
john2
john3
john4
john5 etc...



I just WROTE this in about 5 minutes, here you go:
Code: [Select]@ECHO off
set var1=1
:start
cls
REN "john - %var1%.txt" "john%var1%.txt"
set /a var1+=1

if %errorlevel% == 1 goto done
goto start

:done
cls
echo Finished!
pause
exitAin't gonna work...
Do you see the error ? ?Uh...
It WORKS perfectly to me...the difference between the two lists is
" -"
without the quotes.
I thin it can can be down with Windows Explore.

Batch script:

@echo off
setlocal enabledelayedexpansion
echo Before:
echo.
dir /b John*.txt
echo.
echo Renaming...
echo.
for /f "delims=" %%A in ('dir /b John*.txt') do (
set oldname=%%A
set newname=!oldname:John - =John!
if not exist "!newname!" ren "!oldname!" "!newname!"
)
echo.
echo Done
echo.
echo After:
echo.
dir /b John*.txt
echo.
Pause

Console output:
