A user-defined metalabel is assigned to each of the electronic files. The electronic files are organized as a function of the metalabels into a second hierarchical file structure existing simultaneously with the first hierarchical file structure on the recordable medium of the data processing system. A search query is received from a user and the metalabels of the second hierarchical file structure are searched as a function of the query. Each electronic file having a metalabel matching the query is returned to the user as a search result.
