When a Microsoft HTML Help 1.0 help system is generated, all HTML files, images and scripts are compiled into a single, consolidated help file with the extension .CHM. To view the help system, only the .CHM file itself is needed. The .CHM file can be found in the output folder, which is located in the same folder as your Word document. All other generated files in the output folder can be safely discarded.
