Rename files with a macro

I'm desperate to find/create a macro that will allow the user to specify a path to a folder that contains files... and then give a Find/replace form. This is the code I currently have, however this no longer works in 2007/2010 as Application.FileSearch is no longer an object.

User Forms within the attachment.

Sub FileRename()
 
'   Renames files in any directory by finding and replacing certain areas of the filename

    End With
    
    ActiveWindow.Close
    Application.ScreenUpdating = True
    Application.DisplayAlerts = True
    
End Sub

this is an example to show the files

Sub FileShow()
'   Renames files in any directory by finding and replacing certain areas of the filename
    Set fs = CreateObject("Scripting.FileSystemObject")
    Set f = fs.GetFolder("D:\DATI\prova\")
    Set fc = f.Files
    Range("A1:A1").Select
    Columns("A:A").ColumnWidth = 70
    Columns("B:B").ColumnWidth = 70
    i = 1
    For Each f1 In fc
    Cells(i, 1).Value = f1.Name
    i = i + 1
    Next
    
End Sub
