Large text files comparison

I need a solution to compare 2 large text files (4-6 gb / 200-300 millions lines each) and save the unique lines to another text file.

Example :

[login to view URL]

With "Display Uniques Per List" option checked.

I'd prefer using windows command line but I'm opened to all suggestions.
