Opening ASF files

Did your computer fail to open an ASF file? We explain what ASF files are and recommend software that we know can open or convert your ASF files.

What is an ASF file?

ASF stands for Advanced Streaming Format. The ASF file format was developed by Microsoft for streaming media files. The ASF format is not a file in and of itself, but is rather a file container format.

Files with the .asf extension contain three different objects including a header file, a data object and an optional index object. The header file within the ASF container contains information about the media data. The data object is the actual media stream that the ASF file contains. The optional index object allows for random access to data within the ASF file.

ASF files allow for the compression of media files, making it easier to download the media files and stream them over the Web.
