What is an RP file?
An .RP file is primarily an Axure RP Project File created by Axure Software Solutions. These files store interactive wireframes, user interface designs, and website prototypes. The file uses a standard ZIP compression format internally to hold data and image assets.
However, the .RP file extension is not exclusive to Axure. It also has multiple possible meanings across different software ecosystems. For example, it can be a match replay file for the game Minion Masters by BetaDwarf. It is also used as an XML test execution report collection by Katalon Studio, a Result package by Diatron, or a RealPix Clip file developed by RealNetworks.
How to open RP files?
To open and edit an Axure RP Project File, you need the official Axure RP software. Because the file structure is essentially a compressed archive, you can rename the .RP extension to .ZIP and extract the internal contents using command-line tools or desktop archive utilities like 7-Zip or WinRAR.
If the file is an XML report from Katalon Studio, you can open it with any standard text editor or code editor like Notepad++ or Visual Studio Code.
Best practices and troubleshooting
Because the .RP extension is shared by completely different programs, opening the file in the wrong software will result in corruption warnings or generic error messages. Before trying to open an .RP file, verify whether it is a UI prototype, an XML report, or a game replay.
If you cannot open your file, do not immediately assume the file is broken. It is highly likely that your computer lacks the specific software needed to interpret that particular version of the .RP format.
Summary
viewer.online/rp analyzes .RP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Since the .RP extension has multiple possible meanings, we strongly recommend using viewer.online/rp to identify the actual format of your specific file. Ultimately, viewer.online/rp directly opens and previews .RP files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
