Arranging Icons Annoying Problem

when i go in the finder menu bar then click view>arrange by>name, osx always puts them in alphabetical order but in two columns so i have to scroll down for ages get to the bottom. No matter if i move one icon to make the begining of the 3rd it always goes into 2 columns

I have tried get them into 3 columns but it just puts them in to 2 which is annoying. Anyway i believe this is to do with the .ds_store files. (correct me if im wrong). My questions is this how do i get rid of the ds file and if this is in fact the problem

Cheers
