Opening an MNU File

The MNU file type is primarily associated with LabVIEW.

MNU	File extension: MNU
	File type:	configuration file

What is an MNU file?

MNU files mostly belong to LabVIEW. MNU files are files that store menu configuration data for various applications.
In many cases, these files define the structure and commands for application menus. For example, in LabVIEW environments they serve as a stored list of user interface commands.
Some software uses MNU files for game menus. They regulate how game options appear and function, as seen in setups related to Live for Speed and Grand Prix Legends.
Other implementations use an XML format inside the file, like those in certain point-of-sale systems (for instance, systems from Aspen POS). This XML structure details the hierarchy and functionality of each menu item.
Key points summarized by FilExt.com include:

LabVIEW Menu Files: They hold internal data for menu commands in LabVIEW and are tied to resources from National Instruments.

Game Menu Files: They configure in-game options and menu structure, as used by games like those from Live for Speed and referenced in Grand Prix Legends.

XML Menu Data Files: They use a text-based XML format to arrange menu options, common in applications like Aspen POS (Aspen POS).

FilExt.com tip: To open or view an MNU file, use its host application. If the file is text-based (XML), a plain text editor can also display its contents.

How to open an MNU file

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

MNU file format:

To view or edit MNU files you need to know the file format, because it determines how the data in this file is stored. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below is our analysis of the MNU files:

The MNU file extension is rarely used and includes different formats for the applicable programs. But the following two file formats are common:

• 25% of all MNU files have the same signature RSRC . If you open these files in a text editor, you will see only illegible characters. A typical file size is 2 KB. The file type was primarily used more than 10 years ago. Certain words are almost always found in the files, such as RSRC and LMNULBVW. The following filename is common: dir.mnu.
• 4% of all MNU files internally utilize the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. A typical file size is 340 KB. The files contain the following words: version.

All the rest of the MNU files (71%) have different formats. Tagged as menu. Drag & drop your file here to see the file format and a preview of your MNU file!
