Answer 1

You can use Send To for this. It supports multiple files.

In case this website goes offline:

Open shell:sendto with Windows + R or paste it into your explorer address bar. It should redirect you to:

C:\Users\\AppData\Roaming\Microsoft\Windows\SendTo

Create a shortcut to your program in this folder and you should see it in your explorer right-click menu under Send to
