Interactive File Searching Using File Metadata

Navigation and browsing on a computer system are usually done using the file system hierarchy. However, this is not the most adequate method to search or locate a given file at a later time, unless we know exactly where it is. In this paper, we present a new approach for interactive file search•ing, which takes advantage of the (implicit) metadata asso•ciated to files. With this information we specify a semantic hierarchy that is both used for browsing and filtering the found files. We combine this with an interactive histogram, for overviewing and filtering according to specific metadata, and a dynamic view mechanism, which selects the most ap•propriate representation for the type of file being presented. Experimental tests with users revealed that they can find files faster than with a conventional browser or searching tool and that the semantic hierarchy and filtering mecha•nism were well understood by users.
