Help with locating fonts

[BeastlyHex]

Im using SFML 2.1 on Codeblocks and i want to use arial text on my window but i cant find a way of accessing the arial font with my code. I tried putting the font in the SFML file under graphics but that still does not seem to work. this is the part of the code which is about it.

text.setFont(E:\SFML-2.1\include\SFML\Graphics\arial);
text.setString("hello world");
text.setCharacterSize(24);
text.setColor(sf::Color::Red);

How do i make it so it gets the arial font. Thanks for helping.
