If you use OS X then you might be familiar with the infamous hidden ".DS_Store" files that are produced as a result of using Finder.
The challenge is to write code that will go through the entire file system and delete any file named ".DS_Store".
Classic code golf - shortest code wins.
The code does not need to delete any .DS_Store files that require superuser; assume no such files exist.
The code should only delete the relevant .DS_Store files and nothing else.
