Adobe Flash Player creates Flash video files. These videos can range from simple animations to high quality video files. Often, videos you find on the internet are Flash videos. The file extension that correlates with Flash videos is denoted either .flv or .f4v. Windows Media Player does not come with the ability to play .flv or .f4v files. To play Flash video files in Windows Media Player, you need to download and install a codec which Windows Media Player can use to play additional file types, including .flv and .f4v Flash videos.
