What is a .Q3D file?
A .Q3D file is a type of file known as a Quest3D Project File. It is created using a software called Quest3D. Quest3D is a tool that people use to make 3D applications, which are programs that let you explore or interact with three-dimensional spaces or objects on a computer. Inside a .Q3D file, you will find everything that is needed for a 3D project. This includes .CGR files, which are a part of the 3D project. The main purpose of a .Q3D file is to gather all these pieces into one place so that the 3D applications made with Quest3D can be shared on the internet easily.
To open a .Q3D file, you can use a program called Act-3D Quest3D Viewer. This program lets you view the 3D projects contained in the .Q3D file.
There's something interesting about .Q3D files when it comes to sharing them. They can be published in a way that protects the 3D content inside. This is called "protected mode." When a .Q3D file is in protected mode, the .CGR files inside it are encoded. This means they are scrambled in a way that stops people from being able to open or change them. This is useful for keeping the 3D content safe from being copied or altered without permission.
When .Q3D files are prepared to be shared on the web, they come with two additional files: "index.html" and "createControl.js." These files help the 3D program to start up and run in a web browser, allowing people to view the 3D application online. Alternatively, .Q3D files can also be turned into a stand-alone executable file, which means they can be made into a separate program that runs by itself, without needing to be opened in a web browser.

Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
