Files with an RPN extension have multiple applications in the digital realm. This article aims to acquaint you with the possible formats and ways to make most out of these file formats.

RPN files are used by the Revolutions Pack software as an "add-on" file. These files usually contain additional functionalities, tweaks or themes that can be added to the base software. The Revolutions Pack is a software utility developed to improve the user interface of older Windows versions (like Windows 9x and ME). To open an RPN file with Revolutions Pack, install and run the software, and then select the "Load Add-On" command from the "Add-Ons" menu. Here, select your RPN file.

HP-48GX uses RPN files to store user-entered data or program. To use an RPN file in HP-48GX, transfer the file to the calculator using an HP 48GX connectivity kit.
