What is an IRX file?
An .IRX file typically functions as a PlayStation 2 IOP module. Sony designed these files as ELF executables to control hardware components like audio and USB devices on the PlayStation 2. However, the .IRX extension has multiple possible meanings. It can also be an application security scan result created by HCL AppScan (structured internally as a ZIP archive), a CAD application runtime extension for AutoCAD (formatted as a Windows EXE file), a raster image index file for Intergraph systems (formatted as a TIFF), or a Brewer Irradiation File used by Brewer Data Management Software.
How to open IRX files?
Because the extension represents several distinct formats, you must first identify the correct type. Developers analyzing PlayStation games often use reverse-engineering tools or emulators like PCSX2 to inspect ELF modules. Security professionals use HCL AppScan or a dedicated IRX Viewer to read zipped scan results. CAD professionals use AutoCAD to load runtime extensions, while IrfanView can display Intergraph image indexes.
Best practices and troubleshooting
If your file does not open in these tools, do not rename the extension to guess the format. Instead, viewer.online/irx analyzes .IRX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because the most common .IRX files use the known ELF format, viewer.online/irx can safely open and display them online, eliminating compatibility problems.
