What can a single media file include?

A single media file can include various types of content, such as audio, video, images, or text. It may also contain metadata that provides information about the file, such as its title, artist, or duration. Additionally, multimedia files can incorporate multiple elements, like a video that combines both visual and audio components or an interactive file that allows user engagement. Formats like MP4, MP3, and JPEG exemplify how diverse media can be encapsulated in a single file.
