What is an RTA file?

RTA files mostly belong to iA Writer. When you see a file with the RTA extension, its meaning depends on the context in which it was created.
One common use is as a Rich Text Editor Document produced by iA Writer. In this case the file uses a plist structure to store formatted text. You can open it with iA Writer.
Other RTA files serve very different purposes. For example:
  • Maritime Navigation: These files hold data for a ship voyage plan and work as a route file for navigation systems.
  • Game Resource: Some RTA files contain animation data or other resources. They may be used by tools described as a Real-Time Analyzer or be associated with game resources like those for Resident Evil or Grand Theft Auto.
  • Embedded Systems: In industrial contexts, a RTA file can be an assembler output or a Real-Time Application Protocol file. Such files are handled by tools like Renesas Flash Programmer and RealView Debugger (Renesas).
  • RTOS Loader: There are also RTA files that serve as loader programs for real-time operating systems such as RTOS-32.
  • FilExt.com note: Check the file’s header or its source application to decide which type of RTA file you have.

    How to open RTA files

    You need a suitable software like iA Writer to open an RTA file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your RTA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RTA file directly in the browser:. Just drag the file onto this browser window and drop it.
