What is a ROU file?

ROU files mostly belong to EnRoute CAD. This file extension is used in specialized design environments. It may serve as an EnRoute project file for CAD/CAM design. In some cases, it is a PCB routing file that holds board layout and routing data.
Main Usages:

  • Used in EnRoute CAD/CAM systems. It stores project details and design layouts. For more details, visit Thinksai EnRoute Family.
  • Used in PCB design. It functions as a route outline file for design applications such as those from Altium Designer and Cadence Allegro. More information is available at Altium.

File Handling:
FilExt.com note: These files are not meant for manual editing. They require the proper design software to open, view, and modify the embedded routing and project information.

How to open ROU files
