ASF File Extension Details and Tips


ASF files are developed by Microsoft primarily for streaming media. You may have got a bunch of ASF videos. But what if you want to play ASF files on iPhone, iTunes, QuickTime or share on YouTube, Vimeo, etc? Do you know how to play, stream ASF files easily? Well, it is important to understand exactly what ASF files are. Now we'll introduce the ASF file extension details and tips in this page.

What is ASF

The Advanced Systems Format (ASF) is an extensible file format designed primarily for storing and playing synchronized digital media streams and transmitting them over networks. ASF is the container format for Windows Media Audio and Windows Media Video-based content. The extension wma or wmv is used to specify an ASF file that contains content encoded with the Windows Media Audio and/or Windows Media Video codecs. The Windows Media Format SDK can be used to create and read Windows Media files, as well as ASF files that contain other types of compressed or uncompressed data.

The most common file types contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). Note that the file extension abbreviations are different from the codecs which have the same name. Files containing only WMA audio can be named using a .WMA extension, and files of audio and video content may have the extension .WMV. Both may use the .ASF extension if desired.

How to Play ASF Videos

Microsoft Windows:
On Windows PC, you can use VLC or Windows Media Player to open and view ASF files.
