For instance, if I subclass FolderItem as MyFolderItem and add a

return FolderItems?
You have to convert each standard FolderItem object into an instance
of your subclass. You do this by giving your class a constructor
that takes a FolderItem instance, and pass this into the superclass
constructor. It'd look something like this:
Sub Constructor( orig As FolderItem )
Super.Constructor( orig )
End Sub
...though I don't recall whether the FolderItem constructor is called
"Constructor" or "FolderItem", so you may have to adjust. Then,
whenever you have a FolderItem and want one of your MyFolderItems,
you'd make one like so:
Dim mf as New MyFolderItem( f )
where f is the FolderItem instance.
Is there a better way to do this?
Probably. Consider an extension method instead, or perhaps a wrapper class.
