| Description | .ASF is a file format created by Microsoft, formerly known as Active Streaming Format or Advanced Streaming Format.

| Technical Details | An .asf file may contain video and audio, and can also contain metadata in the same way that MP3 files do. This allows the definition of artist, album etc. The file format allows streaming in a similar method to other formats, allowing the user to view the file once a certain amount of bytes have been downloaded. The file continues to download while the user watches. Due to it being designed for streaming, one disadvantage of ASF is that the maximum resolution is a relatively small 352x288. |
