VB Script to Delete Old Backup Files.

I have created VB Script which deletes 7 days old file in Folder and Sub Folder.

iDaysOld = 7
strPath = "C:\BACKUP"

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(strPath)
Set colSubfolders = objFolder.Subfolders
Set colFiles = objFolder.Files

For Each objFile in colFiles
   If objFile.DateLastModified < (Date() - iDaysOld) Then
       objFile.Delete
   End If
Next

For Each objSubfolder in colSubfolders
   Set colFiles = objSubfolder.Files
   For Each objFile in colFiles
       If objFile.DateLastModified < (Date() - iDaysOld) Then
           objFile.Delete
       End If
   Next
Next
