Abstract
A card adapter includes a first memory card interface configured to be connected to a first memory card. The first memory card is associated with a first file system. The card adapter includes a second memory card interface that is configured to be connected to a second memory card. The second memory card is associated with a second file system. The card adapter also includes a host interface configured to connect to a host. The card adapter includes a controller operatively interposed between the first and second memory card interfaces and the host interface. The controller is configured to control the first memory card interface and the second memory card interface to control connections between each memory card that is connected thereto with the host. The controller is also configured to operate in each of two selectable modes. In a first mode the controller is operative to emulate a virtual file system that presents to the host the first file system and the second file system as a unified image. In a second mode, the controller presents to the host either the first file system of the first memory card connected to the first memory card interface or the second file system of the…
