What are THMX files and how to open them
Are you having problems opening a THMX file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.
What is a THMX file?
A .THMX file is a Microsoft PowerPoint 2007 theme / template file.
Files that contain the .thmx file extension are most commonly associated with theme files that have been created for 2007 and later versions of a variety of Microsoft Office applications.
The THMX files that are used by these programs contain themes that a user can apply to a document or to a presentation that has been created by the associated software. THMX files often contain pre-defined colors, formatting, and fonts and can be used as a template that lets a user create multiple files with a similar look.
THMX files are similar to application template files, but they can be shared across multiple Microsoft Office applications, unlike application template files. For example, a THMX file can be used in both PowerPoint and Word instead of creating a template for both applications.
