What is an ARR file?
An .ARR file is most commonly a MultiMedia Fusion Array File created by Clickteam software. Game developers use these files in Clickteam Fusion to store numerical and text data in grids. This data often includes level layouts, inventory items, and save game states.
Because the .ARR extension is generic, it is also used by other software. An .ARR file might be a source code script for the Pyret programming language, an Autodesk ArtCAM 3D relief model, a CNC Simulator data file, or an Affymetrix microarray XML data set.
How to open ARR files?
To open a MultiMedia Fusion .ARR file, you need Clickteam Fusion. If the file contains Pyret source code, you can open it with any standard text editor, such as Notepad++ or Visual Studio Code. ArtCAM 3D models require Autodesk ArtCAM or a specialized viewer like 3D-Tool.
Using viewer.online for ARR files
Since .ARR has multiple possible meanings, it is difficult to know which program you need. You can use viewer.online/arr to analyze .ARR files to identify the exact format and creator software. Our tool allows you to inspect the file structure, extract readable text, and check whether an online preview is available.
File conversion
If you need to convert an .ARR file, we recommend using convert.guru to convert it to a sensible target format. For example, Pyret source code files can be converted to standard .TXT or .PY files. If the file is an ArtCAM 3D model, you might be able to convert it to standard .STL or .OBJ 3D formats.
Summary
In summary, viewer.online/arr is useful for identifying, inspecting, and understanding .ARR files without installing software or dealing with compatibility problems. It is the fastest way to figure out if your file contains game data, code, or 3D models.
