What is an HXA file?
An HXA file is an attribute definition file used by Microsoft Help 2.x documentation systems. It defines attributes and their possible values, allowing the help viewer to categorize and filter documentation based on selected criteria, such as product, language, or technology. HXA files are stored in the XML standard, making them readable and easy for Help 2.x tools to process.
More Information
Software developers create HXA files when building Microsoft Help 2.x documentation collections. The files work together with other Help 2.x components to control which help topics appear under different filtering conditions, allowing a single documentation set to support multiple products or audiences.
NOTE: Microsoft Help 2.x has been replaced by newer documentation technologies, but HXA files are still encountered in legacy Visual Studio documentation projects and archived Help 2.x collections.
How to open an HXA file
You can open HXA files with Microsoft Help 2.x systems, which are typically used by software developers to manage and deploy help files within applications. To view or edit an HXA file, use an Integrated Development Environment (IDE), such as Microsoft Visual Studio. Alternatively, you can open the file with a text editor, such as Microsoft Notepad or Microsoft Visual Studio Code, as the HXA format is text-based.
