A CHM help file is a type of file format for providing help documentation and user manuals for software applications. CHM stands for “Compiled HTML Help”, which means that the help file is a compiled collection of HTML pages, images, and other multimedia resources that are designed to be accessed through a user interface.
CHM help files are commonly used in Windows-based software applications, and they are accessed through a dedicated viewer program called the HTML Help Viewer. They can be created using the HelpNDoc help authoring tool.
