Open ASF File
An ASF format and extension file is a multimedia file stored in the Advanced Systems Format, hence the acronym.
The ASF format is a proprietary video and audio container format, which stores audio and video data, along with optional metadata, such as title, author, and bibliographic copyright data.
ASF files have been developed by Microsoft primarily for streaming media online.
The ASF container format only specifies the structure of how online video or audio is transmitted, which depends on several factors, such as network bandwidth and server performance.
It is important to know that the ASF format does not specify the encoder used to encode the audio or video stored in the container, which it assumes was designed for the ASF.
The ASF format has gradually been replaced by WMA and WMV files.
That is, if the ASF container format stores audio, it is usually saved as a Windows Media Audio file with a WMA extension, on the other hand, if it stores video, it is usually saved as a Windows Media Video WMV file.
The audio and video data stored in these files can be compressed using a variety of video codecs.
