I am trying to open a .pptx file through a URL. When I click on the URL, it asks me to Open or Save; when I click Open, a prompt again appears asking to either Save or Cancel. If I click Save, I am able to open it.
Whereas, when I click on the URL with the .ppt file, it directly opens up in PowerPoint without the dialog prompting for Open or Save.
I am wondering why the open behavior is different for .pptx versus .ppt' and how I can make.pptxopen like the.ppt` does (i.e. directly)?
