What is a RED file?

RED files mostly belong to Visual Studio Code by Microsoft. A RED file contains redline markup created with CADViewer design review API. A redline markup comprises tags, annotations, notes, comparisons, and comments added to a 2D or 3D design during a review session. Such a RED file is usually displayed as the uppermost layer of a design document. Another type of RED file contains source code written in RED programming language. You can edit this file with a text editor. RED 3D video titling and visual effects editor uses a RED file to store a project. Clarion database application development environment's Modula-2 compiler saves path data in a RED file.

How do you open RED files?

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