What is a RO file?

RO files mostly belong to Google Chrome.

RO files serve different roles depending on the creator.
Some RO files are web pages saved by the Blink engine used in Google Chrome. They hold page data such as HTML, CSS, and images so you can view a snapshot of a site offline.
Other RO files store 3D dental models used in dental design and 3D printing. Software like the 3Shape Dental System creates these files, and similar files are handled by programs such as exocad DentalCAD. You can find more details on the 3Shape website.
Additionally, some RO files are formatted as read-only containers used with machine learning tools. In these cases the files may include an internal format called Source2 and are associated with utilities like tensorflow-converter for neural network models, including those from Qualcomm.
This file extension is not standardized. Its function is defined by the application that creates it. It is important to use the correct software to open and work with each variant.

  • Web content: Use a web browser such as Google Chrome.
  • 3D models: Use dental design programs like 3Shape Dental System or exocad DentalCAD.
  • Neural network models: Use machine learning tools like tensorflow-converter.

How to open RO files

You need a suitable software like Google Chrome to open a RO 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 RO file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RO file directly in the browser:. Just drag the file onto this browser window and drop it.

    ROwin is a firefighting system design software from Procedimientos. It allows users to calculate requirements and design systems consisting of sprinklers and hydrants as well as to conduct simulations. It also allows the users to create their own 3D models. The RO file format stores a project created in ROwin. ROwin is now discontinued and the RO file format is no longer supported.
