Robust File Container
The Advanced Systems Format file container stores the following in one file: audio, multi-bit-rate video, metadata (such as the file's title and author), and index and script commands (such as URLs and closed captioning). The file container supports files as large as 17 million terabytes.
To ensure that content is associated with compatible players, there are several different file extensions. The file extension used should be:
- .WMA for files that include audio compressed with the Windows Media Audio codec, or
- .WMV for files that include both audio and video compressed with Windows Media Audio and Windows Media Video codecs.
- Content compressed with other codecs should be stored in file and use the .ASF extension.
By using separate extensions, users can install multiple players on their system some which may play only audio, and associate with the .WMA extension, and different players that play both audio and video, and associate with the .WMV extension.
