Completely remove (old) git commits from history

Question

I\'m starting a project using git where I\'ll be committing very large files, but only a few times a week. I\'ve tried to use git as-is and it seems to store the entire file

Answer 1

This should be a simple git rebase -i where you have

p A
s B
s C
p D
p E

and then edit the commit message for A-C to be just C's commit message.

git-rebase will "squash" all the commits into a single commit, who's objects are the same as commit C's objects.

Note: It may be possible to use git filter-branch to change the big files in the previous commits to actually match the new ones, if you'd rather do that. But its a dangerous operation and I don't want to give you a bad command on accident.
