I would like to integrate an effective patch building (producing very compact differences) for binary files into my application. Recently I have found a nice solution - DF SDK by Agensoft (http://www.agensoft.com/dfsdk.html
). Downloaded a free Demo - it works fine for me. The DF SDK itself is provided in the form of a single DLL which also suits my needs and moreover - as it is written on the authors website - they are giving a 200$ discount till 15 of December.
Could you please share you experience on this software product or even suggest another noteworthy solution (sold at a reasonable price).
Thanks in advance.
