I have sent a large (>1GB) binary file to a friend over a slow metered data plan and now I need to send the second version of the same file only slightly changed. I want to send only the delta/diff-ed part of it to save the data plan and I want the recipient to easily patch it. We both are using Windows 7. What is the easiest and the most efficient way to do this?

I used xdelta and xdeltagui for Windows to make an XZ-compressed patch file and apply it at the recipient's.
There is another XDelta GUI too, but I have not tested it.
Binary Diff
? There are a number of software packages, but this site isn't for software recommendations I'm afraid.
