git - remove file from the repository

I just realised that my binaries have been version-controlled since I started my git repository, which has resulted in a .git of 10MB -- way too large for 40 revisions of a small project.

How can I retroactively remove these files from the repository? A simple git removal would not remove their history, so th开发者_JS百科ey would keep taking up space.

I'm using TortoiseGit with Unfuddle.

This calls for git filter-branch. You will be able to get rid of the files you never intended on tracking.

Take a look here for more information:

Hope this helps.
