        **oApp.Namespace(FileNameFolder).CopyHere oApp.Namespace(FNAME).items**



        MsgBox "You find the files here: " & FileNameFolder

        On Error Resume Next
        Set FSO = CreateObject("scripting.filesystemobject")
        FSO.DeleteFolder Environ("Temp") & "\Temporary Directory*", True
    End If
End Sub

я получил ошибку 91 (переменная объекта или переменная блока не установлена) в отмеченной строке, и я не понимаю, почему? у кого есть идеи?
