What is an MNU file?
An .MNU file is typically a menu configuration file. Many different software programs use this extension to store the layout of user interface menus, toolbars, and palettes. Because the extension is shared across different industries, an .MNU file can contain plain text, XML, or binary data. Notable examples include the AutoCAD Interface Layout File created by Autodesk, palette menus for National Instruments LabVIEW, custom interface menus for racing simulators like Assetto Corsa, and even POS system menus.
How to open MNU files?
If the .MNU file is saved as plain text or XML, you can open it with text editors like Notepad++ or Visual Studio Code. However, if the file is a binary database (such as those used by the Microsoft Jet Database Engine) or a compiled game asset, a simple text editor will show unreadable characters. To use the menu properly in a working environment, you usually need the exact software that created the file, such as AutoCAD, LabVIEW, or Adobe Photoshop.
