    Dim vArray() As String
    Dim x As Long

    ' Change "*.PPT" to "*.PPTX" or whatever if necessary:
    EnumerateFiles ActivePresentation.Path & "\", "*.PPTX", vArray

    With ActivePresentation
        For x = 1 To UBound(vArray)
            If Len(vArray(x)) > 0 Then
                .Slides.InsertFromFile vArray(x), .Slides.Count

    ByVal sFileSpec As String, _
    ByRef vArray As Variant)
    ' collect all files matching the file spec into vArray, an array of strings

    Dim sTemp As String
    ReDim vArray(1 To 1)

    sTemp = Dir$(sDirectory & sFileSpec)
    Do While Len(sTemp) > 0
        ' NOT the "mother ship" ... current presentation
        If sTemp <> ActivePresentation.Name Then
            ReDim Preserve vArray(1 To UBound(vArray) + 1)
            vArray(UBound(vArray)) = sDirectory & sTemp
        End If
        sTemp = Dir$
    Loop
