Then click 'Open with' and choose an application. If you cannot open your MU file correctly, try to right-click or long-press the 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. You need a suitable software like KSP to open a MU file. Also, earlier versions of Quattro Pro, a spreadsheet application used MU filename extension to store its menu definitions. The part.cfg file found in the directory created by Kerbal Space Program references the model.mu file as a mesh. model.mu files reference texture files in the same directory. MU 3D models are usually saved as model.mu using a proprietary format that is only supported and used by Kerbal Space Program (KSP), a flight simulation game set in space. The MU file extension is primarily associated with 3D meshes used to create the in-game appearance of space shuttle parts and other 3D objects created using Unity 3D, a 3D modelling software. MU files mostly belong to KSP by Private Division.
