My First VB Script to rename folder names

My First VB Script to rename folder names.

This script helped to rename and arrange movie files and movie folders in external hard disk.

Set objFS = CreateObject("Scripting.FileSystemObject")

strFolder = "i:\Movies"

Set objFolder = objFS.GetFolder(strFolder)

For Each Folder In objFolder.SubFolders

strFolderName = Folder.Name

if InStr(strFolderName,"[DVD~RIP]") <> 0 Then

WScript.StdOut.WriteLine "Inside if"

WScript.StdOut.WriteLine strFolderName

strFolderName = Replace(strFolderName, "[DVD~RIP]", "")

Folder.Name=strFolderName

End If
