.AX File

The ax file extension is related to DirectShow (sometimes abbreviated as DS or DShow), codename Quartz, a multimedia framework and API produced by Microsoft for software developers to perform various operations with media files or streams. It is the replacement for Microsoft's earlier Video for Windows technology.

Based on the Microsoft Windows Component Object Model (COM) framework, DirectShow provides a common interface for media across many programming languages, and is an extensible, filter-based framework that can render or record media files on demand at the behest of the user or developer.

The DirectShow development tools and documentation were originally distributed as part of the DirectX SDK, however, they are currently distributed as part of the Windows SDK (formerly known as the Platform SDK).

The ax files contain filter data and basically tell the computer how to read the specific compression method.

An ax file extension is associated with the DirectShow (sometimes abbreviated as DS or DShow).

How to open:

The ax files are used for internal purposes of DirectShow and compatible tools.

How to convert:

As far as we know, this .ax file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
