Trash emptied - restore files?

I just emptied my laptop and then emptied the trash.
Now I can no longer find my important folder on the desktop, which I must have unconsciously dragged along too…

Is there still a way to save the files despite emptying?

There should be enough Youtube guides I haven't looked at any of them myself but I know that you can also restore the completely deleted ones.

Mostly already. There are many programs that promise exactly that and are free. Search for such programs and see which one appeals to you the most
