Advanced Streaming Format is Microsoft’s own digital audio/video container format and is part of the Windows media framework. It can store compressed audio and video content that can be played back using a media player equipped with the proper codec. This extensible file format is designed to keep coordinated multimedia data and supports advanced multimedia capabilities that include extensible media types, component download, and scaleable media. Windows Media Video (WMV) and Windows Media Audio (WMA) are the most common files found in an ASF file and can use the ASF extension. These files can also include the metadata for the audio/video file similar to ID3 tags for MP3 files.
