Abstract: Computer system navigation tools provide “links” to various different files, lists, folders, and/or other storage elements and allow users to organize files, e.g., by hierarchical properties, lists, auto lists, folders, and the like. Such systems and methods allow users to assign properties to a file (optionally in a hierarchical manner), to change assigned properties, to search, view, and retrieve information based on the assigned properties, and the like.

Abstract: In a graphical user interface environment, a situational-specific browser may be used to provide contextually appropriate levels of information for files whose information is to be displayed. As different views of files are to be displayed, the browser may dynamically adjust its configuration to display different types of information, features and/or command options. Different views may be predefined, or new views may be dynamically created in response to user navigation.

Abstract: Systems and methods are provided for storing and retrieving thumbnail images in a per-user/per-system thumbnail cache. One or more data files may be used to store thumbnail images of varying sizes. An index is updated with the location or locations of thumbnails for a particular file, the URL and modification time of which may be used as a key to finding the thumbnails within the index. Direct memory mapping of thumbnail images are provided. Concurrency techniques are utilized to maintain cooperative access to the cache among multiple processes. Cache contents which are orphaned or unused are reclaimed for use by newer or more frequently used thumbnail images.

Abstract: One or more task page dialogs are housed within a frame. Each task page includes a header region and a content region. The header region includes a title serving as a main instruction regarding what input is expected within the content region. The content region includes text and/or user interface controls as defined by an application program requesting creation of the task page. A task page may also contain a footer region having button controls for a user to indicate that he or she has completed the task page and/or to terminate the task (or series of tasks) with which the page is associated. An application program requests creation of a task page by calling a programming interface function. Included in the function call are references to data for each of one or more pages.
