Moving log files

I am using log4net and other logging in my apps, and the logs are filling up the disks of the test server, so I created a Windows Scheduled Task to move logs to an archive disk, and also delete very old logs from the archive. I move logs older than 2 weeks to the archive and delete logs older than a year from that archive. I created this vb-script (started from the scheduled task) to do the job:

'VBScript that moves old log files from C:\LogFiles to E:\LogArchive

'Folders
Const FOLDER = "C:\LogFiles" 
Const BACKUP_FOLDER = "E:\LogArchive" 

'Objects
Dim objFSO, objFolder, objFolder2, objFile 
Set objFSO = CreateObject("Scripting.FileSystemObject") 
Set objFolder = objFSO.GetFolder(FOLDER)

'Loop and move
For Each objFile In objFolder.Files 
  If objFile.DateLastModified < DateAdd("w", -2, Now) Then 
    objFile.Move BACKUP_FOLDER & "\" & objFile.Name 
  End If 
Next

'Delete very old files from target BACKUP_FOLDER
Set objFolder2 = objFSO.GetFolder(BACKUP_FOLDER)
For Each objFile In objFolder2.Files 
  If objFile.DateLastModified < DateAdd("w", -52, Now) Then 
    objFile.Delete
  End If 
Next

Plain old ASP-like code. No Types, everything is just Variant types.
