Documented steps
Clone the repository (optionally as a partial/blobless clone for large repos): `git clone <url> && cd <repo>`. Sparse-checkout can be layered onto any existing clone.
Enable cone-mode sparse-checkout and populate it in one step: `git sparse-checkout set DIR1 DIR2`. Cone mode is the default. This sets `core.sparseCheckout`, `core.sparseCheckoutCone`, and `index.sparse`, writes the directory list to `$GIT_DIR/info/sparse-checkout`, and updates the working tree so all files under DIR1/ and DIR2/ (at any depth) are present, plus files immediately under each ancestor directory and the toplevel.
Verify the active cone: `git sparse-checkout list` — prints the directories currently defining the sparse checkout.
Add more directories without discarding the existing selection: `git sparse-checkout add DIR3`.
Feed directories from a file or pipe instead of CLI args: `printf 'DIR1
DIR2
' | git sparse-checkout set --stdin`.
If a merge, rebase, or conflict resolution materializes files outside the cone, restore sparsity: `git sparse-checkout reapply`.
Remove stray files left outside the cone (requires cone mode): preview with `git sparse-checkout clean --dry-run`, then actually delete with `git sparse-checkout clean --force` (deletion needs `-f`/`--force` unless `clean.requireForce=false`).
Return to a full checkout of all tracked files at any time: `git sparse-checkout disable`.
Known gotchas
Non-cone mode (`--no-cone`, raw gitignore-style patterns) is explicitly called out as deprecated in the docs — always prefer cone mode (plain directory names), which is also the default.
`git sparse-checkout init` is documented as a 'Deprecated command that behaves like set with no specified paths. May be removed in the future.' Use `set` (or `add`) instead of `init`.
The whole sparse-checkout feature is marked experimental in the docs: 'THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR, AND THE BEHAVIOR OF OTHER COMMANDS IN THE PRESENCE OF SPARSE-CHECKOUTS, WILL LIKELY CHANGE IN THE FUTURE.'
`--sparse-index` (opt-in, off by default) rewrites the index into a format older Git versions and some external tools don't understand; if compatibility breaks, disable it to rewrite the index back to a normal (non-sparse) one.
Narrowing the cone can silently delete now-out-of-cone directories that contain only ignored/untracked files; if unignored untracked files remain there, Git warns and skips deletion instead — commit or relocate anything important first.
`git sparse-checkout set` upgrades the repo to use `extensions.worktreeConfig` so sparsity can be worktree-specific; be aware this changes where sparse-checkout config is stored across worktrees.
