  • Search for *.tmp files on your computer.
    Windows may have saved the latest version before it was corrupted or your computer crashed/froze. If you find a.*tmp file (temporary file) which seems to correspond to your ppt file, rename it with the extension .ppt and open it in PowerPoint.
  • Use your latest back-up to repopulate a new presentation.
