Title: Remove old copy before saving new one

Hi Shaun,

I think we should remove the old copies before adding the new ones or we'll end up with ambiguous copies (since we have no concept of revisions here...).

I don't know if this will also get rid of the files as well, so can you please tell me if it doesn't?

Huw.
