Git Garbage Collection Visualized
Git Garbage Collection will clean up any files in the repository that are unreachable. This tutorial using #VisualGit shows the internals of Git once a commit is made unreachable by resetting the branch to the previous commit and then removing the unreachable commit from the Reflog. Running Git Prune then simulates the purge without placing our objects into the Pack file as would occur if we ran the full Git GC command.
