It is necessary in order to open files.

We're not mind-readers. If you want help you need to provide more details.

What files? What do you need? etc.

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,
