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.

Step 1

Download and save a .flv and .f4v codec from the internet. The K Lite Mega Codec Pack (see Resources) is a safe and reliable package of codecs that not only includes what you need to play Flash videos, but many other file types as well.

Step 2

Run the .flv and .f4v codec executable files, following the installation instructions included.

Step 3

Restart your computer to save the installation changes.

Open Windows Media Player and select a Flash video to play.


  • Only download codecs from trusted websites to avoid viruses.


  • If you have trouble watching videos in Windows Media Player, consider using a more versatile media player, such as Windows Media Player Classic or VLC Media Player. These are available online for free.
