HXK File – What is .hxk file and how to open it?

HXK File Format

An HXK file is a Microsoft Help 2 Index File, storing index information used by Microsoft Help 2, an older help system developed by Microsoft for use with its software applications. Index information assists in the efficient searching and retrieval of specific content within help documentation. HXK files organize and structure index data, facilitating quick access to relevant information.

HXK files contain references to help topics, including file names, topic titles, stop words (commonly used words excluded from search results), and other metadata. They provide an efficient way to create and manage indexes, enabling users to navigate help content quickly and easily. HXK files are often used in conjunction with .HHP (Microsoft Help Project File) files, which define the structure and content of help systems. By leveraging HXK files, Microsoft Help 2 provides users with a comprehensive and user-friendly help experience.

Opening HXK Files Using Microsoft Help Viewer

HXK files, also known as Microsoft Help 2 Index Files, are associated with Microsoft’s HTML Help system. These files serve as indices for HTML Help files (.CHM) and contain cross-references and keyword lists to facilitate quick and efficient searching within the help documentation.

To open an HXK file, you will need Microsoft Help Viewer, which is included in most versions of the Windows operating system. Simply double-click on the HXK file, and the Help Viewer will automatically launch and display the associated HTML Help file (.CHM). Within the Help Viewer, you can use the search function to locate specific topics or keywords using the index information stored in the HXK file. This enables convenient navigation and instant access to relevant help content.

Third-Party Software for HXK Files

If you do not have Microsoft Help Viewer installed or encounter compatibility issues, you can use third-party software to open HXK files. Several programs support HXK file viewing, including:

• CHM Viewer: A dedicated application designed specifically for opening and viewing CHM (Compiled HTML Help) files, including HXK index files.
• File Viewer Plus: A comprehensive file viewer that supports a wide range of file formats, including HXK files.
• Universal Viewer: A versatile file viewer that allows you to view and convert HXK files to other formats, such as PDF or TXT.

These third-party software options provide alternative ways to access the information contained in HXK files, particularly when the Microsoft Help Viewer is unavailable or incompatible with your system.

HXK File Format

HXK files are Microsoft Help 2 Index files used to store indexes for Microsoft Help 2 (HLP) files. These files facilitate the navigation and search functionality within HLP help systems, allowing users to quickly locate specific information. HXK files contain a structured index of the topics and keywords found in the associated HLP file.

HXK File Structure

HXK files consist of a header followed by a series of data blocks. The header contains metadata about the HLP file, including its version and the number of data blocks. Each data block represents a different aspect of the HLP index, such as a list of topics, a list of keywords, or a cross-reference table. The data blocks are organized into a hierarchical structure that allows for efficient searching and retrieval of information. The structured format of HXK files ensures fast and reliable searching within HLP help systems.
