What is an RPX file?
An .RPX file usually stores a report layout for ActiveReports, a reporting software component created by MESCIUS (formerly GrapeCity). These files contain design structures for data reports and use standard XML or UTF-8 formats.
Alternatively, an .RPX file can be a Wii U Executable file. Developers use these ELF format files to test and run games on the Nintendo Wii U console. Other uses include power and timing summary reports in the Xilinx Vivado design suite or business documents in Računovodstvo Pro Plus.
How to open RPX files?
To open a report layout, developers use ActiveReports. Because these report files use standard XML, you can also open and inspect them with any basic text editor like Notepad++ or Visual Studio Code.
For Wii U game files, you need specific console emulators like Cemu to load the executable code.
Best practices and troubleshooting
If your .RPX file does not open, check its contents in a simple text editor. If you see readable text and tags, it is a report layout. If you see scrambled characters, it is likely a compiled Wii U game or a compressed file. Do not rename the file extension, as this will not change the actual file type.
Software and tools
Summary
viewer.online/rpx analyzes .RPX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because many .RPX files use the known UTF-8 format, viewer.online/rpx can safely open and display them online, eliminating compatibility problems. Since .RPX has multiple possible meanings, we recommend using viewer.online/rpx to identify the actual format of your file.
