免费在线 PPTM 转 PDB 转换器

A file that stores macro-enabled slide shows and presentations. It was introduced together with the development of PowerPoint 2007. PPTM stores audio, video, images and text with different formatting styles. The file contains an XML structure and can handle embedded macros. To use embedded macros in PPTX, you must first save the file as .PPTM.

This format was used for storing databases on the Pegasus and Palm PDA devices. Besides images, PDB allowed you to store tables, maps, e-books, and other data in a structured way. Today it has become obsolete and has been replaced by more flexible formats with DRM protection.
