New document opening all previously made files

[Carla250278201tjj]

Everytime I create make a "New File" or even Open one from my desktop, All previously made documents and files open into the workboard as well. As seen below i only intended to create a single new file but it has opened a previously made one as well, Is there a way of turning this feature off so each file opens in its own workboard?

Did you already try to restart your machine? Reset preferences?

I just did and it still opens all files
