Abstract

A method of providing file data for a media file from a file system, where the format of the file requires that the file comprise a plurality of segments of file data located at pre-declared locations within the file. The file data making up the file is based upon derived file data. After receiving a request to open the file, a maximum segment length for the file is determined based on the desired properties of the file. In response to a request for the location of a segment within the file, a location calculated by considering each segment of the file to have the maximum segment length is returned. In response to a request for file data from a segment of the file, generated file data for the segment is returned, where the generated file data comprises the derived file data and padding data to give the generated file data the maximum segment length.
