How to place a resourse in the applicationDocumentsDirectory
<p>I have an App that will come with a video clip.  The user will be able to add video clips at a later stage.  These will end up in the applicationDocumentsDirectory. 
How, and where, do I place the first clip so it ends up in the right place?  The clip is about 25Mb so I don't really want to duplicate it.</p>
