Specialized network fileserver

摘要

A method and apparatus of a portable storage device that provides a specialized network fileserver is described. In an exemplary method, the portable storage device retrieves a list of applications on the portable storage device, where each of the applications has a private filesystem. For each of the applications, the portable storage device determines if that application will share the corresponding private filesystem and adds that private filesystem to a shared filesystem of the portable storage device is that is shareable. The portable storage device further advertises the shared filesystem to a host that is coupled to the portable storage device.

1. A computerized method, comprising:
at a fileserver implemented on a portable storage device:
receiving, from a host computer that is communicatively coupled to the portable storage device, a request to construct within the portable storage device a shared filesystem;retrieving a list of a plurality of applications resident on the portable storage device, wherein each application of the plurality of applications has a corresponding private filesystem, and each private filesystem is in a security sandbox that prevents non-corresponding applications from accessing the private filesystem;constructing the shared filesystem within the portable storage device by carrying out steps that include:
determining, for each application of the plurality of applications, whether the application is configured to share with the host computer a specific category of data that is included in the private file system, andfor each application that is configured to share with the host computer the specific category of data:
adding, to the shared filesystem, a link to the corresponding private filesystem, wherein the link enables the host computer to access the specific category of data, but not other categories of data, via the shared filesystem; andadvertising the shared filesystem of the portable storage device to the host computer.
