What is a FLR file?
A .FLR file is primarily a vector animation file created by Rive (formerly known as Flare by 2Dimensions). Designers use these files to build interactive vector animations for games and applications. Many of these .FLR files store data in a text-based JSON format.
Because file extensions can be shared between different programs, a .FLR file might also be a Flare Decompiled ActionScript File created by the Flare decompiler. Furthermore, classic games like *The Sims* or *SimCity 2000* by Maxis use the .FLR extension to store floor tile data.
How to open FLR files?
You can open Flare vector animations directly using the online Rive editor. Some users also export these animations using Adobe After Effects. If the file is a Flare Decompiled ActionScript File, you can open it with a simple text editor like Notepad++ or Visual Studio Code.
Best practices and troubleshooting
Since .FLR files can serve very different purposes, it is important to know the file's origin. Trying to open a game data file in a vector animation editor will cause errors. If you are unsure what software created your file, you should inspect the file contents first.
Analyze and view FLR files online
viewer.online/flr can analyze .FLR files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/flr is useful for identifying, inspecting, and understanding .FLR files without installing software or dealing with compatibility problems. Because the .FLR extension has multiple possible meanings, we recommend using viewer.online/flr to identify the actual format of your file.
