   It's a 265MB file with 71 slides, and it's corrupt (according to   
   PowerPoint 2003 anyway).   
      
   Tried to open it with LibreOffice Impress 25.2.7.2 (X86_64)   
      
   The GuhNoo crapware hard-locked my Win11 system??!?!?  wtf?  Complete   
   freeze - couldn't even open Task Mgr.  No mouse or keyboard.  Just a   
   frozen screen.  Waited about 5 minutes.  No change.  Nothing to do but   
   hard shutdown.  Unbelievable!   
      
   Restarted and tried LO Impress again, with smaller known good .pptx   
   files.  This time LO ran some kind of 'updating...' code.  Then it   
   opened the known good files just fine.   
      
   Then it opened the corrupted file!!!!   yeah!   
      
   Saved it to .pdf and .odp, and both files were the same 265MB. Normally,   
   71 slides should be ~10MB to 50MB max in .pdf format.   
      
   So I saved it to Powerpoint 2003 format, and the output file was 42MB.   
      
   Opened that in PP2003 and printed to .pdf, and the .pdf was 15MB.   
      
    From 265MB to 15MB!  Success!   
      
   Couldn't have done it without LO (without searching for an online file   
   recovery service).
