Replace substring in all files in all subfolders


I'm looking for a vb script or a .bat script to rename all my files in a folder (and subfolders).


There are 4 subfolders in a folder, with names like newyear2010, easter2010, christmas2010.
And I would like to rename the 2010 into 2011.

Can you guys help me?

Powershell variation:

$RootPath = "C:\TEMP\Subfolder"

$Files = Get-ChildItem $RootPath -Recurse | ? {$_.PSIsContainer -eq $False}

foreach ($File in $Files)
	if ($File.Name -match "2010")
		$NewFileName = ($File.Name).Replace("2010","2011")
		Rename-Item $File.FullName $NewFileName
		Write-Host -ForegroundColor "yellow" "Renamed File : $($File.FullName) to $NewFileName"

Dim fso, f, sf

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.GetFolder("c:\folder")
For Each sf In f.SubFolders
    If Right(sf.Name, 4) = "2010" Then sf.Move Replace(sf.Path, "2010", "2011")
Set sf = Nothing
Set f = Nothing
Set fso = Nothing

Here's a BAT approach, since that was one of the ones you showed interest in.  If you go this route I'd appreciate it if you could ad the NS-DOS zone to the question before closing it.  Save the below and adjust the BaseDir as needed.

@echo off
setlocal EnableDelayedExpansion
set BaseDir=c:\EE\EE27327959
for /F "tokens=*" %%A in ('dir /B /S /AD "%BaseDir%\*2010*"') do (
  set NewName=%%~nA
  set NewName=!NewName:2010=2011!
  ren "%%~A" "!NewName!"
