Information processing method, apparatus, and system for a multimedia presentation system with a file update process
First Claim
1. An information processing method in which material files and scenario files that control the material files are recorded in storage means and in which data of a set of material files is reproduced based on a corresponding scenario file recorded in the storage means, said method comprising:
- a first processing step of processing a predetermined scenario file recorded in the storage means so as to make the predetermined scenario file nonreadable;
a determination step of determining unnecessary material files from the material files recorded in the storage means, wherein the unnecessary material files are material files that are not controlled by any scenario file other than the predetermined scenario file that has been processed to be unreadable; and
a second processing step of processing the unnecessary material files controlled by the predetermined scenario file to make the unnecessary material files nonreadable.

Abstract
In a system for recording scenario and material files into a storage unit and reproducing the material files based on the scenario file, an information processing method easily and surely prevents unnecessary material files from accumulating in the storage unit by, when a scenario file recorded in a hard disk is deleted, unnecessary material files in this hard disk are automatically deleted. Namely, in the hard disk, the scenario file to be deleted and a scenario file to remain are compared with each other, and material files that are used by the scenario file to be deleted and not used by the remaining scenario file are deleted.
