摘要

Methods for generating file relationship data, and media file systems that generate file relationship data A method of generating, in a media file system comprising a data store and a file record database, file relationship data for a first media file in the media file system. The method determines the essence data in the data store from which the first media file was derived, by determining from the file record for the media file in the file record database details of any previous media files in the media file system from which the media file was created. If the media file was not created from any previous media files, the essence data in the data store that constitutes the media file is determined from the file record. If on the other hand the media file was created from any previous media files, the previous steps are repeated for the previous media files. The file relationship data is the generated using the details of the determined essence data.
