Abstract: A file system shell is provided. One aspect of the shell provides virtual folders which expose regular files and folders to users in different views based on their metadata instead of the actual physical underlying file system structure on the disk. Users are able to work with the virtual folders through direct manipulation (e.g., clicking and dragging, copying, pasting, etc.). Filters are provided for narrowing down sets of items. Quick links are provided which can be clicked on to generate useful views of the sets of items. Libraries are provided which consist of large groups of usable types of items that can be associated together, along with functions and tools related to the items. A virtual address bar is provided which comprises a plurality of segments, each segment corresponding to a filter for selecting content. A shell browser is provided with which users can readily identify an item based on the metadata associated with that item.

Abstract: A previewing system that permits selection from a plurality of interactive previewers for use in a system shell browser is disclosed. The previews may be extensible, such that different application developers may write custom previews for different file types, and the shell browser may follow established criteria to select an appropriate preview. The user may enter criteria to control which previewers are used for different situations, such as when certain file types are selected for previewing. Size of an available display area for the preview may be a criterion, such that resizing the preview area may cause a different preview to be displayed. The preview may be executed as a separate process from the browser so that crashes and hangs in the previewer process do not fatally affect the browser process. Previews may be incorporated within common file dialogs offered by an underlying operating system, such that different applications may share the common previewer.

Abstract: A system and method for device selection in a computer system. In certain systems a user may be required to pick a device from a known set of devices. For example, in a video conferencing application, a user may be required to pick which video camera will be utilized for the session. In one embodiment of the invention, the device selection process comprises the following steps. First, the caller creates the device picker (which in turn creates the common file dialog object). Then, the caller may choose an item filter to use and then initializes the device picker with that item filter. Then the device picker displays all the relevant devices in a common file dialog, and the user may choose a device. After a device is chosen, the device picker returns the reference to that device back to the caller.
