An AX file is a DirectShow filter. DirectShow, codename Quartz, is a multimedia framework by Microsoft. It is used by Windows Media Player and video players to process video streams. Windows Media Player uses AX files when recording TV shows. Files with AX extension can be system, configuration or temporary files. They contain data used by one software for its own purposes.
To open an unknown AX file, determine its file format first. Files have an initial signature called “magic bytes” to indicate format. One extension can be used by different programs and formats. When a file has problems, finding its true format is the first troubleshooting step.
AX files are for internal use of DirectShow and its tools. The AX format likely can’t convert to other formats. Other software also uses the AX extension for its own types of data files. Overall AX files have a “Low” popularity rating. They are not very common on the average computer.
