What is a HPJ File?

A HPJ file is a project file that is created using RoboHelp, a popular program by Adobe Systems Incorporated for creating help files. These files include project settings and links to other files that are used in the Help project. Despite its general usage in creating Help documentation, the utility of HPJ files extends to other areas too.

HPJ Files and RoboHelp

The RoboHelp application by Adobe is the prevalent tool for creating HPJ files. RoboHelp is a Help authoring tool (HAT) that allows users to create help systems and e-learning content for desktop and web applications. Once a Help project has been completed, the HPJ file can be compiled into a final Help file with another extension, like CHM, HLP, or HTML.

Alternative Methods to Open HPJ Files

There are other alternative software that can open HPJ files. These include KeyTools HpjToChm and Help & Manual. The former is a conversion tool that transfigures HPJ files into CHM files, whereas the latter is a full-featured software for creating help and tutorials.

Furthermore, be aware that HPJ files originated from a time when Windows had an 8.3 filename limitation. This might cause compatibility issues with modern systems.
