Description
A CHW file, or Compiled Help Index File, is a type of file associated with Microsoft Compiled HTML Help, a proprietary format for online help files developed by Microsoft. This file specifically stores the index for a help file, allowing users to search and locate information quickly within the help documentation. The CHW file works in conjunction with a CHM file, which contains the actual help content, including text, images, and navigation.
