What file format does ActivePrez create?

Active Prez > Pre-sales Questions
Because ActivePrez is fully integrated into Microsoft PowerPoint, it supports/creates files in the formats supported by PowerPoint such as .ppt and .pps for PowerPoint 2003 and .pptx, .ppts, .pptm for PowerPoint 2007 and later. For PowerPoint 2007 and later, when certain active features are enabled in ActivePrez, the file format needs to be changed from the default .pptx to a macro enabled file format such as .pptm.
