What is a AX file (a file with file extension AX)?

The .ax file extension is used by a number of video playback applications, but it is most commonly associated with the Microsoft DirectShow filter file. This file format allows a user to view Internet videos in real time without having to download the entire file onto his or her hard drive and watch the video after the file download.

The AX file format allows for video file decompression, rendering of video files, decoding and encoding, file parsing and de-multiplexing in order to stream the video over the Internet. This enhances video play-back functionality.

AX files can act as plug-in files, incorporating several of the functions of the file into the programs that support the file format. Apple QuickTime Player and Microsoft Windows Player both support the AX file format.
