You can use Show Package Contents on the .ofocus file and rename root=B0A416EB-7833-4258-A047-59DEEFAF57E9C80989A8-CCC9-485E-AD42-C88AE8EE6D0F.xml to root=B0A416EB-7833-4258-A047-59DEEFAF57E9C80989A8-CCC9-485E-AD42-C88AE8EE6D0F.xml to root=B0A416EB-7833-4258-A047-59DEEFAF57E9:C80989A8-CCC9-485E-AD42-C88AE8EE6D0F.xml
