The ASF format is an extensible format for storing synchronized media data. ASF data is often transmitted over various types of networks using various protocols, and may also be played back from your local computer. ASF supports features like extensible media types, component loading, scalable media types, author-defined stream importance, multilingual support, and rich content and document management.

Typically, ASF files that contain sound recordings that happen to be rich in the Windows Media Audio (WMA) codec have the WMA extension. Likewise, ASF files containing audio, video, or mixed recordings which are packed using the Windows Media Audio (WMA) and Windows Media Video (WMV) codecs develop the WMV extension. If the content in the file is packed using a new codec, then a file provides the ASF extension.
