Git Worktrees Let You Manage Multiple Branches Without Duplicate Clones

Developers often end up with multiple cloned copies of the same repository for different branches or experiments, leading to duplicated history and inconsistent remote tracking. Git worktrees solve this by allowing multiple checked-out working directories to share a single underlying repository. Each worktree maintains its own branch, staged changes, and working files, while commits, tags, remotes, and fetched objects remain common across all of them. A single fetch from any worktree instantly updates remote references for all others, eliminating the need to sync each clone separately. The approach also reduces disk usage on large repositories by avoiding redundant copies of the full Git object database.
