Abstract
An embodiment of the invention is directed to providing robust file system information for non-native devices. In operation, a file system includes both a file storage area for providing access to the contents of files, and a metadata store. The metadata store stores metadata associated with each file or device. When a device is connected to the file system, metadata for that device, and its items, is generated and stored in the metadata store. The metadata persists within the metadata store when the device is disconnected from, or no longer available to, the file system.
