How to import file directly from my system download folder into the raw directory Using Laravel

I want to push a button in my laravel application. That button should copy the excel file from the download folder and save it into symlink storage directory. What should I use then to grab a file from downlaods.

I'm new and I don't see a lot of good explanations of the process. I would be just as happy if someone just pointed me in the right direction. Thanks in advance.
