Notes about the ASF file extension:



Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The ASF file type is primarily associated with 'Advanced Streaming Format' by Microsoft Corporation. Advanced Streaming Format is an open file format specification for streaming multimedia files containing text, graphics, sound, video, and animation. Advanced Streaming Format (ASF) does not define the format for any media streams within the file. Rather, it defines a standardized, extensible file container that is not dependent on a particular operating system or communication protocol, or on a particular method (such as HTML or MPEG 4) used to compose the data stream in the file. An ASF file consists of three objects: a Header object containing information about the file itself, a Data object containing the media streams, and an optional Index object that can help support random access to data within the file. The ASF specification has been submitted to the ISO (International Organization for Standardization) for consideration. A number of programs capture this file extension.
