What is an APA file?
An .APA file is primarily an RSView Development Project Archive or an HMI application archive. Rockwell Automation uses these files in their FactoryTalk View software. Engineers use .APA files to back up and transfer machine interface screens and settings. Sometimes, an .APA file is an APA style citation export from the Authenticus publication repository.
How to open APA files?
To open industrial .APA files, you need FactoryTalk View Studio by Rockwell Automation. You must use the Application Manager tool to restore the .APA archive into an active project. If your .APA file is a citation export, you can open it with text editors like Notepad++ or import it into reference managers.
Best practices and troubleshooting
If an .APA archive fails to restore in FactoryTalk View, verify that your software version matches or is newer than the version used to create the archive. Because the .APA extension has multiple possible meanings, we recommend using viewer.online/apa to identify the actual format of your file.
Summary
viewer.online/apa analyzes .APA files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because .APA files use the known DOC format, viewer.online/apa can safely open and display them online, eliminating compatibility problems.
