Open MSO files
You cannot say in general which program can be used to open MSO files, as they are used in different areas. We give you an overview of the most common file formats with the extension .MSO.
MSO from Microsoft Office
If a user sends an e-mail from a Microsoft Office application such as Word or Excel (from version 2000), there is a file with the MSO extension in its attachment. This so-called Microsoft Office rendering data file should correctly represent the email.
- If you are using Outlook from version 2000, the file is not displayed.
- Other mail programs such as Thunderbird cannot handle the file extension. You will then see the file as an attachment and can easily ignore it.
MSO as Microsoft Office macro reference file
If you save a document as an HTML file with Microsoft Office, the software sometimes creates an additional MSO file. This contains the information necessary to display the document correctly.
- The file can therefore not be executed or edited directly.
MSO from "Microsoft Organization Chart"
MSO files can belong to the "Microsoft Organization Chart" software. With this application, organization charts can be created and edited in Office 2003 programs.
- You can open the file with the free tool "Microsoft Organization Chart 2.0".
MSO as a "Microsoft ActiveX ActiveMime" file
Files with the MSO extension can also be associated with Microsoft's ActiveX framework. The operating system automatically accesses the files if required; you do not have to open them separately.
MSO from "MathLab" and "LabView"
The "LabView" programming environment can also create and edit MSO files together with the "MathScript" extension. These then contain corresponding program codes.
- To open the MSO file, you must install both "LabView" and the "MathScript" extension.
- The program automatically links MSO files to LabView so that you can then simply open the files with a double click.
- Alternatively, the file can also be loaded via LabView itself.
MSO from MedlySound
The music software "MedlySound" also uses the file extension MSO. The program is only available for AmigaOS.
- There is no PC software that allows you to play or edit the file. You must either use an Amiga computer and "MedlySound" or install an emulator like "WinUAE".
Did you know? Windows 7 can simply hide unnecessary file extensions. You can read here how it works.
