What is an HHC file?

HHC files mostly belong to HTML Help Workshop. HHC files are HTML Help Contents files used by Microsoft HTML Help Workshop.
They store the organized list of help topics that form the table of contents for compiled help systems such as .CHM files. The file is written in plain text using HTML markup, which means you can open it with any text editor to see or edit the code.
Key details compiled by FilExt.com include:

Purpose: It provides the navigation structure for help documents by listing topics and subtopics.

Format: The file is encoded in HTML or UTF-8 and employs standard HTML tags (like <li>) for list items.
