What is a EFTX file?

Eftx file extension has Office 2007 Theme Effect file type, developed by Microsoft, which is associated with the "settings files" category.

These are theme effects that can be added to Microsoft Office 2007 (and later version as well) documents and presentations. Effects stored in EFTX files can be applied to tables, shapes, charts, pictures, WordArt, SmartArt graphics, and text. There are several types of effects that can be used: line effects, fills and special effects like shadows or 3D. Every EFTX file includes a data subset saved in a THMX file. With EFTX files editors can easily maintain the same look and feel for multiple documents and presentations. Office 2008 for Mac does not support the .EFTX format.
