The hxc file extension is used by Microsoft Help Workshop. The *.hxc file defines properties and points to other files. When using Help Workshop, it adds the file to a new Help project. The file updates when you save or compile. The .hxc files are in XML format.
You cannot access HXC files although HelpStudio is installed. Make sure the software is up to date. Updated versions may support more formats. Older HelpStudio versions can handle formats of older software versions.
HXC files are not compatible with HelpStudio. One cause is outdated software. Most recent HelpStudio versions are backward compatible. They can handle older supported formats.
How to open HXC files: Use Microsoft Visual Studio. It will handle the file if HelpStudio does not. Other programs also support HXC files. Make sure to update software that handles HXC files.
Be careful with .hxc files from unknown sources. They may be harmful. Various programs can use the .hxc file extension, not just expected ones. This includes potentially harmful software or malware that creates .hxc files.
