Abstract
An information processing apparatus that enhances reliability for complete deletion while shortening response time required for the next process to become executable. A request for deletion of a data file stored in a nonvolatile storage medium is issued. Based on the issuance of the deletion request, data composition information is acquired from file management information in the data file requested to be deleted. The acquired data composition information is moved to a complete deletion data file. The file management information in the data file requested to be deleted is completely deleted by overwriting. After the file management information is completely deleted, a data portion corresponding to the data composition information moved to the complete deletion data file is completely deleted by overwriting. After the data portion is completely deleted, the data composition information moved to the complete deletion data file is completely deleted.
