Use the BFG Repo-Cleaner, a simpler, faster alternative to
git-filter-branch specifically designed for removing unwanted files from Git history.
Carefully follow the usage instructions, the core part is just this:
$ java -jar bfg.jar --strip-blobs-bigger-than 100M my-repo.git
Any files over 100MB in size (that aren’t in your latest commit) will be removed from your Git repository’s history. You can then use
git gc to clean away the dead data:
$ git gc --prune=now --aggressive
The BFG is typically at least 10-50x faster than running
git-filter-branch, and generally easier to use.
