I need in order to open file

@Joseph Kunihiro 

To open/view PDF files on your computer, you need a .pdf format-supported application.

You can download the Acrobat Reader desktop app (freeware) from here: https://helpx.adobe.com/reader/get-started.html 

If you had another question and was referring to something else, then please share more details as requested above.

Thanks,

What files? What do you need? etc.
