Бесплатный онлайн конвертер LRF в PPS

Is a format developed by Sony for its proprietary Sony Reader devices. Files in this format may contain text and images. The format is XML-based.

The file stores slides with presentations and slide shows filled with graphics, audio, video, and textual information. The format is identical to the PPT file, except for the editing feature, and is a bit smaller. Can be opened only in preview mode and prevents other users from changing the structure and content of the presentation.
