.MNU File Extension

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.

To open a .mnu file, you need compatible software that supports this file format.
