What is a MO file

MO files mostly belong to Gettext by Free Software Foundation. A MO file is an object generated from source code (M3 file) written in Modula-3 programming language. This file can be created, edited, and compiled using CM3-IDE. A different MO file contains a thermal, mechanical, hydraulic, or electrical model written in Modelica multi-domain modeling language. Computer-aided engineering programs that use Modelica scripting language to create models include CATIA, SimulationX, and Dymola. Another type of MO file is a machine object which defines language/country specification for a multilingual application developed with Gettext. The contents of a machine object (MO) file are generated from a portable object (PO) file containing source material.

How can I open a MO file?

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

Programs that open and convert MO files:

  1. Gettext by Free Software Foundation
    See the previous paragraphs to learn more about the main application. MO files are often referred to as Gettext developers because this type of file is primarily created or used by this software.
  2. CM3-IDE (object) by elego
    CM3-IDE is an integrated development environment for building applications in Modula-3 programming language. Modula-3 source code is saved in an M3 file. An object generated from an M3 file is saved in a MO file. This file format is classified as Developer.
  3. Dymola (model) by Dassault Systèmes
    Dymola is a computer-aided engineering software used for 3D modeling and simulation. It uses a MO file to store a model written in Modelica language. This file format is classified as CAD. Related links: Modelica Language

MO file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the MO files:

The MO extension is very commonly found and uses a standardized format supported by many programs. The file formats most commonly found in MO files are:

All other MO files (13%) have different formats, such as JSON, within and model. Tagged as global, translation, vehicles, builder, event, texts or base. If you want to find out which format your MO file belongs to, just click on the button "Choose your .mo file to analyze".

a mo machine object is a special file format by Free Software Foundation and should only be edited and saved with the appropriate software.

How to solve problems with MO files

  • Associate the MO file extension with the correct application.
  • Update your software that should actually open machine objects. Because only the current version supports the latest MO file format. Search, therefore, e.g. on the Free Software Foundation manufacturer website after an available Gettext update.
  • To make sure that your MO file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
