No. It's theoretically possible to reverse a delta, but to do that, you must have both A and B available. This is because the representation of the delta between A and B does not show content that was removed, only content that was copied from a and new content added to B. -- Brane -- Branko Čibej Director of Subversion | WANdisco | www.wandisco.com
