Abstract: Methods and systems for media file management are provided. When a plurality of media files in the electronic device are viewed, media data is real-time generated for the media files. In the generation of the media data, the media files are analyzed to obtain a theme for the media files. Then, a script file is identified according to the theme, and media data is produced for the media files according to the script file. In some embodiments, a frame buffer used for storing the media data is refreshed after each frame of the media data is rendered.
