Adobe RoboHelp is authoring software for creating help systems and technical documentation. An RTA file contains configuration information used by RoboHelp while working with a project.
The file is intended to work with the other files in its RoboHelp project. It is a software-specific configuration format, not a general-purpose document or interchange format, and is associated with Adobe RoboHelp for Microsoft Windows.
Open the RTA file with Adobe RoboHelp on Microsoft Windows. In normal use, RoboHelp reads the file as part of the relevant project or configuration data rather than displaying it as an independent document.
If opening the file directly does not work, open the associated RoboHelp project instead and allow RoboHelp to load its configuration files.
An RTA file is not normally converted as a standalone file. Its configuration data is intended for use by Adobe RoboHelp.
To change or preserve the associated help project, open the project in RoboHelp and use the software's export or publishing features where appropriate.
