What is a THMX file?

THMX files mostly belong to Office by Microsoft. THMX is the file format associated with an Office theme. Office is a suite of productivity software developed by Microsoft. It includes a word processor, a spreadsheet software, a presentation software, a database management system, an email software, and a desktop publishing software. THMX files are used to customize the appearance of Office documents and apply the same style and formatting consistently. They can be used to modify the colors, fonts, and effects in a document. Office themes can be applied across different Office applications. The THMX format is a binary format and was introduced in Office 2007. Office comes with pre-defined themes, and users can also create custom Office themes using PowerPoint, which are saved as THMX files. To save the current appearance settings as a theme in an Office application, select Save As in the File menu. In the Save As dialog box, select Office Theme as the file type and click on Save.

How do you open THMX files?
