What is the difference between .pptm and .fb2?

Description: Macro-enabled presentation created by Microsoft PowerPoint, a program used to create presentations and slide shows; contains a collection of slides, including their text, layout, images, and embedded macros; commonly used to store business, marketing, and academic presentation materials.; The FB2 (FictionBook 2.0 File) format is an open XML-based ebook format specifically designed for fictional literature, although it can also accommodate non-fiction. Unlike other ebook formats, FB2 focuses on the structure and content of the book, rather than its appearance. This means that the layout, font, and styling are determined by the e-reader device or software, offering a more uniform reading experience across different platforms.
