Close All But Active

From time to time I find that I have opened a slew of documents, just to help me understand the one document I'm working on.
In this case I want to violate my Golden Rule of "Never Close, never Minimize", and close all open documents EXCEPT THE ACTIVE DOCUMENT without saving a single one; discard all recent changes.
This little macro does the trick.

Public Sub CloseAllButActive()
    ''' Close all open documents EXCEPT THE ACTIVE DOCUMENT without saving a single one; discard all recent changes.
    If Documents.Count > 0 Then
        Dim docSave As Document
        Set docSave = ActiveDocument
        Dim doc As Document
        For Each doc In Application.Documents
            If doc <> docSave Then
                doc.Close savechanges:=wdDoNotSaveChanges
            Else
            End If
        Next doc
    Else ' nothing to do
    End If
End Sub
