ASF File - What Is an ASF File and How do I Open It?

Mac and Windows PCs come baked with their own media players. For example, Windows users can open an ASF file (Microsoft developed) using Windows Media Player. But the same can't be said about Apple QuickTime Player. Because it supports a limited number of formats, Mac users must convert ASF to MP4 or MOV to open this file format. Also, you must do the same to open ASF on Android or iOS devices. So, this post reviews some excellent ASF multimedia players for Mac/Win and how to encode ASF to MP4 and other formats quickly and losslessly.

Part 1. What is an ASF file?

ASF (Advanced Systems Format) is a video container released by Microsoft in 1996. ASF is meant for streaming digital audio/video, and it has a .asf filename extension. That aside, ASF is not a media format per se. Instead, it's a container for WMA (Windows Media Audio) and WMV (Windows Media Video). ASF can also contain metadata like genre, year, artist, etc.

Unfortunately, ASF isn't compatible with open-source licenses. In other words, you need to get a license from Microsoft to distribute files in ASF. Also, Mac, iPhone, and Android don't offer native support for ASF. This container-based format is common for distributing files over the internet using RTSP or MMS protocol.
