What is the tool for this?

Tim was just asking if you were talking about a file ending in .ppt or 
one ending in .pptx. You can just tell by the extension of the file name 
and you don't really need to know when it was created. The .pptx 
extension indicates that it's a newer file format being used by 
Microsoft, which is why Tim called it a newer .pptx file.

I too appreciate the information Tim provided, and if this lead me to 
files that had a better format and were easier to work with then I'd do 
whatever it would take to get them. I can always make things more 
efficient with scripting if I need to perform a task multiple times, but 
ending up with a more accurate file will end up saving time in the long 
run.
