Here is a VBS script to delete all file older then 10 days in d:\backup.

Set the active constraint to “True” if you want to delete the files.

Const Active = False
Const sSource = "d:\backup"
Const MaxAge = 10 'days
Const Recursive = True

Checked = 0
Deleted = 0

Set oFSO = CreateObject("Scripting.FileSystemObject")
if active then verb = "Deleting """ Else verb = "Old file: """
CheckFolder oFSO.GetFolder(sSource)

WScript.echo
if Active then verb = " file(s) deleted" Else verb = " file(s) would be
deleted"
WScript.Echo Checked & " file(s) checked, " & Deleted & verb

Sub CheckFolder (oFldr)
For Each oFile In oFldr.Files
Checked = Checked + 1
If DateDiff("D", oFile.DateLastModified, Now()) > MaxAge Then
Deleted = Deleted + 1
WScript.Echo verb & oFile.Path & """"
If Active Then oFile.Delete
End If
Next

if not Recursive then Exit Sub
For Each oSubfolder In oFldr.Subfolders
CheckFolder(oSubfolder)
Next
End Sub
