How to remove unreferenced blobs from my git repo

Question

I have a GitHub repo that had two branches - master & release.

The release branch contained binary distribution files that were contributing to a very large repo

To add another tip, don't forget to use git remote prune to delete the obsolete branches of your remotes before using git gc

you can see them with git branch -a

It's often useful when you fetch from github and forked repositories...
