What is an FRW file?
An .FRW file is most often a KOMPAS-3D Fragment file. ASCON develops KOMPAS-3D, a popular Computer-Aided Design (CAD) software. Engineers use .FRW files to store 2D drawing fragments, sketches, or specific mechanical parts. These files allow users to reuse standard elements across different CAD projects.
However, the .FRW extension has other uses. It can be a RollerCoaster Tycoon 3 Fireworks Effects File used by games published by Atari. It is also used as a batch process log file by Interference Prediction Software (IPS) or a process summary report by CSPro. Because an .FRW file can contain different types of data, viewer.online/frw analyzes .FRW files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
How to open FRW files?
To open an .FRW CAD file on your computer, you need KOMPAS-3D or the free KOMPAS-3D Viewer application. If the file is a text-based log from CSPro or IPS, you can use any standard text editor. For game files, the .FRW file must be placed in the correct installation folder for RollerCoaster Tycoon 3 to read the custom firework effects.
Best practices and troubleshooting
If you do not know the origin of your .FRW file, do not rename the extension. Renaming does not convert the file. Instead, inspect the file contents. Many modern .FRW CAD files are structured as compressed archives.
Summary
Because .FRW files use the known ZIP format under the hood, viewer.online/frw can safely open and display them online, eliminating compatibility problems.
