What is an ARR file?

ARR files mostly belong to CNC Simulator. ARR files are not a single standard format. They serve many purposes depending on the software that created them.

CNC Simulation Data: These files store game data for simulation software. For example, CNC Simulator uses an ARR file to keep its simulation settings and game assets. Visit CNC Simulator for details.

MFU Game Data Storage: Some ARR files hold game data for MFU systems, working as storage containers for in‑game arrays.

Pyret Source Code: In some cases, ARR files contain source code for the Pyret programming language. Such files can be opened in specialized editors (like PyCharm) or via environments that support Pyret. More info is available at Pyret.

Affymetrix Array Data: An ARR file may be in XML format and store microarray data used in genetic expression analysis. This format is supported by tools such as Expression Console and GenomeStudio. See Thermo Fisher for further information.

Fuzor Asset Archives: Certain ARR files are proprietary archives that hold digital assets for Fuzor software.

3D Model Archives: Some ARR files are crafted as compressed archives to store 3D models. They are used with tools like 3D-Tool.

FilExt.com notes: Each ARR file’s structure and content is defined by the originating application. To open and view an ARR file, use its native software. If the file is text based, a plain text editor might reveal its contents.

How to open an ARR file

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

ARR file format:

To view or edit ARR files you need to know the file format, because it determines how the data in this file is stored. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the ARR files is as follows:

An ARR file covers different formats for different programs. However, the following two file formats are common:

20% of all ARR files have the same signature CNC ARRAY. These are binary files, so they do not contain words or text. The file size is in the range of 590 bytes to 310 KB. The file type is relatively new. The following keywords are characteristic: CNC ARRAY. A common filename is ini.arr or da.arr. Files like these are about save and array.
15% of all ARR files use the same file format, which can be identified by the letters "MFU ARRAY" at the beginning. If you open these files in a text editor, you will see only illegible characters. Most of these files are 430 bytes to 870 KB in size. The files contain the following words: MFU ARRAY. The file name Save1.arr or save.arr is typical for these files.

All other ARR files (65%) have no uniform format, often, for example, XML, Source, include, use, Arrival and VRAK. Tagged as group, module, small, problem, solving or code. If you want to find out which format your ARR file belongs to, just click on the button "Choose your .arr file to analyze".

How to solve problems with ARR files

Associate the ARR file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest ARR file format. Search, therefore, e.g. on the manufacturer website after an available CNC Simulator update.
To make sure that your ARR file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
