Abstract:
1. A method of managing user data-files in a portable digital apparatus having a display device, and an interface for a recording medium, the method comprising the steps of: generating representative voice files and data-files in a corresponding directory through manipulation by a user, each representative voice file for describing a group of the data-files to be stored in the corresponding directory, the representative voice files and data-files having respective names including sequentially arranged file indices based on the order of generation of the representative voice files and the data-files; grouping the data-files into groups of files such that each respective group is associated with its representative voice file based on the file indices of the representative voice files and the data-files; selectively displaying on the display device representative data-files of each of the groups in the corresponding directory; locating the corresponding directory to store data-files among directories formed on the recording medium; and setting the located corresponding directory as a present directory; wherein the name of the corresponding directory includes a directory index and a characteristic code therein; wherein by the file generation step, the name of each of the representative voice files includes the directory index of the corresponding directory, a characteristic code, and a data-file index; wherein by the file generation step, the name of each of the data-files includes a characteristic code and a data-file index; wherein the file generation step comprises the steps of: increasing the highest index of the indices of the files stored in the corresponding directory by “1” to set the increased index as a present data-file index (i.e., a first step); generating a representative voice file to which the present data-file index is assigned, according to manipulation by the user, and increasing the present data-file index by “1” (i.e., a second step); and generating at least one data-file to which the present data-file index is assigned according to manipulation by the user and increasing the present data-file index by “1” (i.e., a third step).
