Corrupt PowerPoint

[JTPOTATO]

Hi Guys,

 

I've got a powerpoint file that just decided to corrupt itself, after trying to run the auto repair in office, it still fails and says "Can't read file"

 

I've unblocked the file in properties, just wondering if there's anything that I can really try?

 

Thanks

It's very possible that the presentation is unrecoverable, though you can try opening the presentation with the following methods:

• Run PowerPoint in Safe Mode. (Win+R, enter powerpoint.exe /safe in Run)
• Open the file in Word and recover if prompted.
• Open the file in LibreOffice Impress and recover if prompted.

... along with these untested methods suggested on Technet:
