The best part of PowerPoint Recovery is that it supports PowerPoint 2016 unlike others. I really like how it works and it provides detailed instructions to use it.This is the amazing utility which repairs corrupt PPT, PPTX and PPTM files to get back all the inaccessible data. The tool restores different objects of PowerPoint, such as header, tables, footers, WordArt objects and charts. Use Free Version & See Preview of Recoverable Lost PPT Files.
Good luck
