# Reach another folder with \input

How do I reach a file in another folder when using \input?

E.g. I have my main document frontpage.tex in a folder called main and a file chapter1.tex in a folder chapters. How do I in frontpage.tex reach the chapter1.tex with a command like the following, which I can't get working:

\input{..\chapters\chapter1}
