Do you have to be a "nerd"?

I don't understand the app, especially the instructions that don't lead anywhere. I have to go to "Available Shares" because dragging and dropping the movie folder directly into the app doesn't work. Where do I find that? There's a "My SMB" section, whatever that is. But after three minutes, it says there's an error. It's definitely not intuitive. I can access all my data smoothly through Finder. I thought that would be enough.
