Hi, Everyone. This is Bo Chen. I am interested in the idea of "Better big-file support".

As it is described in the idea page, "Many large files (like media) do not delta very well. However, some do (like VM disk images). Git could split large objects into smaller chunks, similar to bup, and find deltas between these much more manageable chunks. There are some preliminary patches in this direction, but they are in need of review and expansion."

Can anyone elaborate a little bit why many large files do not delta very well? Is it a general problem or a specific problem just for Git? I am really new to Git, can anyone give me some hints on which source codes I should read to learn more about the current code on delta operation? It is said that "there are some preliminary patches in this direction", where can I find these patches?

I will appreciate it if anyone can offer some help.
Thanks.
Bo Chen
