APA - RSView Development Project Archive

What is a APA file

The APA format and files with the .apa extension are associated with the RSView Studio and RSView ME programs. These programs are used for software development. Projects that are created using the RSView programs save their projects in the APA format. These project files thus store all kinds of work-in-progress information for the software developed. The software in question is used to create Human-Machine-Interface (HMI) and control applications.

APA files are, technically archive files that store project information. Thanks to the archiving, these project work-in-progress files can be shared among multiple computers where RSView Studio or similar programs by Rockwell Automation are installed. APA files are commonly found on Windows computers since RSView Studio and RSView ME are Windows-based programs. The file format is mostly deprecated by now since it was used to create applications on Windows 2000 and XP, Windows versions that have been replaced for some by now.

Here's a small, but not exhaustive list of programs that can open APA documents:

  • Rockwell Automation RSView Studio (Windows)
  • RSView ME (Windows)
