What is a .HHC file?

The .HHC file extension stands for HTML Help Table of Contents. It is a type of file specifically used in creating help documentation for Windows software. These files are generated by a program called HTML Help Workshop, which was designed to help developers create help systems that are integrated into Windows applications.

The .HHC file contains the table of contents for the help documentation. This table of contents acts like a site map, organizing and linking the different sections and topics of the help documentation so that users can easily navigate through them. The format allows the help content to be viewed and navigated using a web browser, making it accessible and user-friendly.

Although the .HHC files are crucial for structuring help documentation, it's important to note that the primary software used to create and open these files, Microsoft HTML Help Workshop, has been discontinued. This means that while existing .HHC files can still be used, the software to create new ones or edit existing ones might not be supported or available in the future. However, users who still have access to this software can use it to open and work with .HHC files.
