.MNU File Extension

Interface layout definition file used by AutoCAD 2D and 3D CAD software as well as 3ds Max 3D modeling software; contains ASCII text definitions that specify the display properties of user interface elements; used for customizing the layout of the user workspace.

MNU files were used by older AutoCAD versions prior to AutoCAD 2006. The default interface layout was stored in a file named acad.mnu, which could be supplemented with additional custom layouts.

For AutoCAD software, MNU files are similar to .MNS files, which use the same format, but do not contain any comments or special formatting.

NOTE: MNU files were replaced by .CUI files in AutoCAD 2006. CUI files were then replaced by the new .CUIX files in AutoCAD 2010. CUIX files can be generated from MNU files in AutoCAD 2010 using the Transfer tab of the CUI command.

File used by Adobe Photoshop, an image-editing program; contains menu configuration information, such as which menu items are displayed; also can be used for specifying highlighted menu items.

The Photoshop CS5 installation includes a file named "New in CS 5.mnu," which highlights all of the new menu options available with the CS5 version. You can double-click this file to set the menu configuration, or access it by selecting Window → Workspace... → New in CS 5.

Menu file used by TomTom GPS navigation devices; contains definitions for the menu items that are displayed on the device's interface; can be edited with a text editor to customize the order of the menu options.

To customize the TomTom menu, users can create a TomTom.mnu text file that specifies the menu items and display order, and place it in a SdkRegistry directory on the device.

Menu declarations are divided into several sections, which include headers such as MENUBLOCK|BLOCK_MAIN|BTM_GPS_POSITION| followed by statements such as
MENUPAGE|TASK_PAGE1|Main Menu 1 of 3|, and MENUITEM|TASK_NAVIGATE_TO|.

TomTom files can be uploaded by connecting your device to a Windows or Mac computer via a USB connection.
