What are files with the .asf extension used for?

Files with an .asf extension are multimedia documents created in order to reproduce and transfer audiovisual content online and in digital format, without having to download them completely beforehand. Files of the .asf type are thus used to play and transmit streaming media, also improving the quality of compressed audio and video content.

Although the usefulness of ASF files is recognized, there are still questions about how to open them on most devices. Next, you will see how to open your ASF extension documents according to the device you have.
