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. An object previewer in a shell browser is provided which is configured to display a plurality of items representing multiple item types.

112. The method of claim 101, further comprising a virtual address bar method for providing a virtual path to items stored in a computer file system using a virtual address bar, the virtual address bar method comprising:

displaying a virtual address bar operable to include a first interactive segment, wherein the first interactive segment references items on the computer file system according to a corresponding filter for selecting items; and

adding one or more additional interactive segment to the virtual address bar, wherein each additional interactive segment further restricts the items referenced by the preceding interactive segments;

wherein the first interactive segment and the one or more additional interactive segments comprise a virtual path.

113. The method of claim 101, further comprising providing a virtual address bar user interface control for selecting items accessible to a computer system for display, the virtual address bar comprising:

a plurality of interactive segments, wherein each interactive segment corresponds to a filter for selecting items for display.

114. The method of claim 101, further comprising a method of filtering items, the method of filtering items comprising:

providing a plurality of display objects on the display that each represent one or more items;
