ASF is a proprietary audio and video container format developed by Microsoft and used mainly for streaming multimedia content over the internet.

Advanced Systems files can store both video and audio data and may also contain metadata such as author, title or copyright information. The ASF format only indicates the structure of the audio stream, not the compression method used.

Usually, ASF files contain Windows Media Video or Windows Media Audio data. They can also be compressed with a wide range of video codecs.
