Abstract: A system and method for presenting related items to a user. A universal data store is provided which contains a plurality of items. A portion of the items contain relational information that allows relationships between two or more of the plurality of items to be determined. A shell presents a selected item to a user and is configured to utilize the relational information to present one or more items in the data store which are related to the selected item.

Abstract: A system and method for filtering and organizing items from computer memories based on common elements. In accordance with one aspect of the invention, filters are provided for manipulating the items. The filters are essentially tools for narrowing down a set of items. In one embodiment, the filters are dynamically generated based on the properties of the separate items. The system utilizes virtual folders. The virtual folders 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. In accordance with another aspect of the invention, quick links are provided. In one embodiment, quick links are a set of predefined links (e.g., located on the left side of the display) that can be clicked on to generate useful views of the sets of items. In accordance with another aspect of the invention, libraries are provided. Libraries consist of large groups of usable types of items that can be associated together.

Abstract: A system and method utilizing virtual folders. The virtual folders 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. The virtual folders contain collections of items. The system includes a folder processor that obtains queries from a user and a relational database for storing information about the items. The folder processor first obtains a query from a user and passes the query to the relational database. The relational database provides results back to the folder processor, and based on the results from the relational database, the folder processor provides the results to the user as virtual folders. Users are able to work with the virtual folders through direct manipulation (e.g., clicking and dragging, copying, pasting, etc.).

Abstract: A file system for displaying items of different types and from different physical locations. In accordance with one aspect of the invention, a wide scope of items may be available. In other words, the system is able to represent items from multiple physical locations (e.g., different hard drives, different computers, different network locations, etc.) so that to a user all the items appear to be from one location. The file system utilizes virtual folders. The virtual folders 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. In accordance with another aspect of the invention, non-file items may be represented in the virtual folders. In other words, files that are stored in memory are located in a physical store. The virtual folders can be made to include items that are not currently represented in the physical store. Examples of non-file items are e-mails and contacts.

Abstract: A standard user interface enables a user to filter an arbitrary unfamiliar data set intuitively and effectively. The illustrated interface includes a header control presenting labels, filters, and pulldown menus for each attribute of a data set, presented by an associated display control. The control communicates with a data provider through a set of APIs included in the computer's operating system. Through these APIs the data provider indicates the labels and menus to be displayed, while the header control passes new filter criteria to the data provider as it is specified by the user. The data provider filters the data set according to the user-specified filter criteria, and returns the filtered data set for display by the display control. Desirably, new filter criteria are passed to the data provider as they are being typed by the user, allowing the data provider to return successively smaller sets of result data, thus giving the visual impression of a shrinking data set.
