Apparatus for processing data of program

摘要

Most recorded data are necessary program data in the prior art. As the recording area of a recording medium such as a hard disk or an optical medium is increased, however, most recorded data become unnecessary data. Therefore, a demand of easily deleting such unnecessary data becomes stronger. To this end, there is provided a program deleting apparatus in which an unnecessary program extractor extracts specific program data or program data associated with program information and automatically deletes the specific program data and the extracted program data. The program deleting apparatus also can display a list of the extracted unnecessary program information on a monitor to prompt a user to specify unnecessary program or programs to be actually deleted on the basis of the displayed information.
