Description

Help project created with either WinHelp or RoboHelp help authoring software; used for creating program Help documentation; contains information that defines the behavior, look, and content of the Help system.

Help project files include all the information the compiler needs to combine topic files and other elements into a single Help file. They typically include the following sections: Alias, Baggage, Buildtags, Config, Files, Map, and Windows.

HPJ is the native format used by WinHelp's Help Workshop, but is also recognized by third-party help authoring tools. RoboHelp program was originally created by eHelp, but is now owned by Adobe Systems.
