.HPJ File

The hpj file extension is associated with Microsoft WinHelp.

The hpj files are help projects created with either WinHelp or RoboHelp help authoring software. The programs are used for creating program Help documentation, which contains information that defines the behaviour, 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.

The HPJ is the native format used by WinHelp's Help Workshop, but is also recognized by some third-party help authoring tools, such as RoboHelp program, which was originally created by eHelp, but was acquired by Adobe Systems.

A hpj file extension is related to the Microsoft WinHelp, a tool for creating and viewing Help documents in Microsoft Windows apps.
