every day work

[Magmaquito7]

Every day I work with my .pptx presentation in MS PowerPoint 2013. Some hours ago I have finished my work and saved it. I have decided to check my file. And file hasn't opened.

You have backups, right?

A couple of possible work-arounds. I like the "importing the slides in a blank presentation" option - as a suggestion.

Go to the previous versions tab of that folder and restore from there.

Not sure if this will help but best of luck. A previous version may be better than no version.
