Well, off the top of my head, you could use something like:
Public Iterator Function AllFiles(RootDirectory As String) As
IEnumerable(Of String)
Dim Roots As New Queue(Of String) From {RootDirectory}
While Roots.Any
Dim Root = Roots.Pop
Roots.AddRange(IO.Directory.GetDirectories(Root))
For Each Filename in IO.Directory.GetFiles(Root)
Yield Filename
Next
End While
End Function
