What is a .HHK file?
The .HHK file extension stands for HTML Help Index. It is a type of file used specifically for help documentation within Windows operating systems. These files are created by a program called Microsoft HTML Help. The main purpose of an .HHK file is to store an index or list of keywords. When someone using the help documentation clicks on one of these keywords, they are directed to a specific help page related to that term. This makes it much easier and faster for users to find the information they need, as they can simply click on a keyword instead of searching through the entire documentation.
To open or work with .HHK files, you would typically use the Microsoft HTML Help Workshop program. However, it's important to note that this program has been discontinued, which means it is no longer being updated or supported by Microsoft. Despite this, the program might still be available for download from third-party websites, and existing installations can still open and manage .HHK files. Since it's a specialized file type, there aren't many other programs designed to open .HHK files, so if you're working with HTML Help documentation, Microsoft HTML Help Workshop, despite being discontinued, remains one of the primary tools for this purpose.
