How do I clone a subdirectory only of a Git repository?

I have my Git repository which, at the root, has two sub directories:

/finisht
/static

When this was in SVN, /finisht was checked out in one place, while /static was checked out elsewhere, like so:

svn co svn+ssh://[email protected]/home/admin/repos/finisht/static static

Is there a way to do this with Git?

What you are trying to do is called a sparse checkout, and that feature was added in git 1.7.0 (Feb. 2012). The steps to do a sparse clone are as follows:

mkdir <repo>
cd <repo>
git init
git remote add -f origin <url>

This creates an empty repository with your remote, and fetches all objects but doesn't check them out. Then do:

git config core.sparseCheckout true

Now you need to define which files/folders you want to actually check out. This is done by listing them in .git/info/sparse-checkout, eg:

echo "some/dir/" >> .git/info/sparse-checkout
echo "another/sub/tree" >> .git/info/sparse-checkout

Last but not least, update your empty repo with the state from the remote:

git pull origin master

You will now have files "checked out" for some/dir and another/sub/tree on your file system (with those paths still), and no other paths present.

You might want to have a look at the extended tutorial and you should probably read the official documentation for sparse checkout and read-tree.

As a function:

function git_sparse_clone() (
  rurl="$1" localdir="$2" && shift 2

  mkdir -p "$localdir"
  cd "$localdir"

  git init
  git remote add -f origin "$rurl"

  git config core.sparseCheckout true

  # Loops over remaining args
  for i; do
    echo "$i" >> .git/info/sparse-checkout
  done

  git pull origin master
)

Usage:

git_sparse_clone "http://github.com/tj/n" "./local/location" "/bin"

---

Note that this will still download the whole repository from the server – only the checkout is reduced in size. At the moment it is not possible to clone only a single directory. But if you don't need the history of the repository, you can at least save on bandwidth by creating a shallow clone. See udondan's answer below for information on how to combine shallow clone and sparse checkout.

---

As of git 2.25.0 (Jan 2020) an experimental sparse-checkout command is added in git:

git sparse-checkout init
# same as: 
# git config core.sparseCheckout true

git sparse-checkout set "A/B"
# same as:
# echo "A/B" >> .git/info/sparse-checkout

git sparse-checkout list
# same as:
# cat .git/info/sparse-checkout

git clone --filter from git 2.19 now works on GitHub (tested 2021-01-14, git 2.30.0)

This option was added together with an update to the remote protocol, and it truly prevents objects from being downloaded from the server.

E.g., to clone only objects required for d1 of this minimal test repository: https://github.com/cirosantilli/test-git-partial-clone I can do:

git clone \
  --depth 1  \
  --filter=blob:none  \
  --sparse \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git sparse-checkout set d1

Here's a less minimal and more realistic version at https://github.com/cirosantilli/test-git-partial-clone-big-small

git clone \
  --depth 1  \
  --filter=blob:none  \
  --sparse \
  https://github.com/cirosantilli/test-git-partial-clone-big-small \
;
cd test-git-partial-clone-big-small
git sparse-checkout set small

That repository contains:

• a big directory with 10 10MB files
• a small directory with 1000 files of size one byte

All contents are pseudo-random and therefore incompressible.

Clone times on my 36.4 Mbps internet:

• full: 24s
• partial: "instantaneous"

The sparse-checkout part is also needed unfortunately. You can also only download certain files with the much more understandable:

git clone \
  --depth 1  \
  --filter=blob:none  \
  --no-checkout \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git checkout master -- d1

but that method for some reason downloads files one by one very slowly, making it unusable unless you have very few files in the directory.

Analysis of the objects in the minimal repository

The clone command obtains only:

• a single commit object with the tip of the master branch
• all 4 tree objects of the repository:
  • toplevel directory of commit
  • the the three directories d1, d2, master

Then, the git sparse-checkout set command fetches only the missing blobs (files) from the server:

• d1/a
• d1/b

Even better, later on GitHub will likely start supporting:

  --filter=blob:none \
  --filter=tree:0 \

where --filter=tree:0 from Git 2.20 will prevent the unnecessary clone fetch of all tree objects, and allow it to be deferred to checkout. But on my 2020-09-18 test that fails with:

fatal: invalid filter-spec 'combine:blob:none+tree:0'

presumably because the --filter=combine: composite filter (added in Git 2.24, implied by multiple --filter) is not yet implemented.

I observed which objects were fetched with:

git verify-pack -v .git/objects/pack/*.pack

as mentioned at: https://stackoverflow.com/questions/7348698/git-how-to-list-all-objects-in-the-database/18793029#18793029 It does not give me a super clear indication of what each object is exactly, but it does say the type of each object (commit, tree, blob), and since there are so few objects in that minimal repo, I can unambiguously deduce what each object is.

git rev-list --objects --all did produce clearer output with paths for tree/blobs, but it unfortunately fetches some objects when I run it, which makes it hard to determine what was fetched when, let me know if anyone has a better command.

TODO find GitHub announcement that saying when they started supporting it. https://github.blog/2020-01-17-bring-your-monorepo-down-to-size-with-sparse-checkout/ from 2020-01-17 already mentions --filter blob:none.

git sparse-checkout

I think this command is meant to manage a settings file that says "I only care about these subtrees" so that future commands will only affect those subtrees. But it is a bit hard to be sure because the current documentation is a bit... sparse ;-)

It does not, by itself, prevent the fetching of blobs.

If this understanding is correct, then this would be a good complement to git clone --filter described above, as it would prevent unintentional fetching of more objects if you intend to do git operations in the partial cloned repo.

When I tried on Git 2.25.1:

git clone \
  --depth 1 \
  --filter=blob:none \
  --no-checkout \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git sparse-checkout init

it didn't work because the init actually fetched all objects.

However, in Git 2.28 it didn't fetch the objects as desired. But then if I do:

git sparse-checkout set d1

d1 is not fetched and checked out, even though this explicitly says it should: https://github.blog/2020-01-17-bring-your-monorepo-down-to-size-with-sparse-checkout/#sparse-checkout-and-partial-clones With disclaimer:

> Keep an eye out for the partial clone feature to become generally available[1]. > > [1]: GitHub is still evaluating this feature internally while it’s enabled on a select few repositories (including the example used in this post). As the feature stabilizes and matures, we’ll keep you updated with its progress.

So yeah, it's just too hard to be certain at the moment, thanks in part to the joys of GitHub being closed source. But let's keep an eye on it.

Command breakdown

The server should be configured with:

git config --local uploadpack.allowfilter 1
git config --local uploadpack.allowanysha1inwant 1

Command breakdown:

• --filter=blob:none skips all blobs, but still fetches all tree objects

• --filter=tree:0 skips the unneeded trees: https://www.spinics.net/lists/git/msg342006.html

• --depth 1 already implies --single-branch, see also: https://stackoverflow.com/questions/1778088/how-to-clone-a-single-branch-in-git

• file://$(path) is required to overcome git clone protocol shenanigans: https://stackoverflow.com/questions/47307578/how-to-shallow-clone-a-local-git-repository-with-a-relative-path

• --filter=combine:FILTER1+FILTER2 is the syntax to use multiple filters at once, trying to pass --filter for some reason fails with: "multiple filter-specs cannot be combined". This was added in Git 2.24 at e987df5fe62b8b29be4cdcdeb3704681ada2b29e "list-objects-filter: implement composite filters"

  Edit: on Git 2.28, I experimentally see that --filter=FILTER1 --filter FILTER2 also has the same effect, since GitHub does not implement combine: yet as of 2020-09-18 and complains fatal: invalid filter-spec 'combine:blob:none+tree:0'. TODO introduced in which version?

The format of --filter is documented on man git-rev-list.

Docs on Git tree:

Conclusions: all blobs from outside of d1/ are missing. E.g. 0975df9b39e23c15f63db194df7f45c76528bccb, which is d2/b is not there after checking out d1/a.

Note that root/root and mybranch/mybranch are also missing, but --depth 1 hides that from the list of missing files. If you remove --depth 1, then they show on the list of missing files.

I have a dream

This feature could revolutionize Git.

Imagine having all the code base of your enterprise in a single repo without ugly third-party tools like repo.

Imagine storing huge blobs directly in the repo without any ugly third party extensions.

Imagine if GitHub would allow per file / directory metadata like stars and permissions, so you can store all your personal stuff under a single repo.

Imagine if submodules were treated exactly like regular directories: just request a tree SHA, and a DNS-like mechanism resolves your request, first looking on your local ~/.git, then first to closer servers (your enterprise's mirror / cache) and ending up on GitHub.

EDIT: As of Git 2.19, this is finally possible, as can be seen in this answer.

Consider upvoting that answer.

Note: in Git 2.19, only client-side support is implemented, server-side support is still missing, so it only works when cloning local repositories. Also note that large Git hosters, e.g. GitHub, don't actually use the Git server, they use their own implementation, so even if support shows up in the Git server, it does not automatically mean that it works on Git hosters. (OTOH, since they don't use the Git server, they could implement it faster in their own implementations before it shows up in Git server.)

---

No, that's not possible in Git.

Implementing something like this in Git would be a substantial effort and it would mean that the integrity of the clientside repository could no longer be guaranteed. If you are interested, search for discussions on "sparse clone" and "sparse fetch" on the git mailinglist.

In general, the consensus in the Git community is that if you have several directories that are always checked out independently, then these are really two different projects and should live in two different repositories. You can glue them back together using Git Submodules.

You can combine the sparse checkout and the shallow clone features. The shallow clone cuts off the history and the sparse checkout only pulls the files matching your patterns.

git init <repo>
cd <repo>
git remote add origin <url>
git config core.sparsecheckout true
echo "finisht/*" >> .git/info/sparse-checkout
git pull --depth=1 origin master

You'll need minimum git 1.9 for this to work. Tested it myself only with 2.2.0 and 2.2.2.

This way you'll be still able to push, which is not possible with git archive.

For other users who just want to download a file/folder from github, simply use:

svn export <repo>/trunk/<folder>

e.g.

svn export https://github.com/lodash/lodash.com/trunk/docs

(yes, that's svn here. apparently in 2016 you still need svn to simply download some github files)

Courtesy: https://stackoverflow.com/questions/7106012/download-a-single-folder-or-directory-from-a-github-repo

Important - Make sure you update the github URL and replace /tree/master/ with '/trunk/'.

As bash script:

git-download(){
	folder=${@/tree\/master/trunk}
	folder=${folder/blob\/master/trunk}
	svn export $folder
}

Note This method downloads a folder, does not clone/checkout it. You can't push changes back to the repository. On the other hand - this results in smaller download compared to sparse checkout or shallow checkout.

If you never plan to interact with the repository from which you cloned, you can do a full git clone and rewrite your repository using

git filter-branch --subdirectory-filter <subdirectory>

This way, at least the history will be preserved.

This looks far simpler:

git archive --remote=<repo_url> <branch> <path> | tar xvf -

Git 1.7.0 has “sparse checkouts”. See “core.sparseCheckout” in the git config manpage, “Sparse checkout” in the git read-tree manpage, and “Skip-worktree bit” in the git update-index manpage.

The interface is not as convenient as SVN’s (e.g. there is no way to make a sparse checkout at the time of an initial clone), but the base functionality upon which simpler interfaces could be built is now available.

It's not possible to clone subdirectory only with Git, but below are few workarounds.

Filter branch

You may want to rewrite the repository to look as if trunk/public_html/ had been its project root, and discard all other history (using filter-branch), try on already checkout branch:

git filter-branch --subdirectory-filter trunk/public_html -- --all

^{Notes: The -- that separates filter-branch options from revision options, and the --all to rewrite all branches and tags. All information including original commit times or merge information will be preserved. This command honors .git/info/grafts file and refs in the refs/replace/ namespace, so if you have any grafts or replacement refs defined, running this command will make them permanent.}

> Warning! The rewritten history will have different object names for all the objects and will not converge with the original branch. You will not be able to easily push and distribute the rewritten branch on top of the original branch. Please do not use this command if you do not know the full implications, and avoid using it anyway, if a simple single commit would suffice to fix your problem.

---

Sparse checkout

Here are simple steps with sparse checkout approach which will populate the working directory sparsely, so you can tell Git which folder(s) or file(s) in the working directory are worth checking out.

1. Clone repository as usual (--no-checkout is optional):

    git clone --no-checkout git@foo/bar.git
    cd bar
   

^{You may skip this step, if you've your repository already cloned.}

^{Hint: For large repos, consider shallow clone (--depth 1) to checkout only latest revision or/and --single-branch only.}

1. Enable sparseCheckout option:

    git config core.sparseCheckout true
   

2. Specify folder(s) for sparse checkout (without space at the end):

    echo "trunk/public_html/*"> .git/info/sparse-checkout
   

or edit .git/info/sparse-checkout.

1. Checkout the branch (e.g. master):

    git checkout master
   

Now you should have selected folders in your current directory.

You may consider symbolic links if you've too many levels of directories or filtering branch instead.

---

This will clone a specific folder and remove all history not related to it.

git clone --single-branch -b {branch} git@github.com:{user}/{repo}.git
git filter-branch --subdirectory-filter {path/to/folder} HEAD
git remote remove origin
git remote add origin git@github.com:{user}/{new-repo}.git
git push -u origin master

I just wrote a script for GitHub.

Usage:

python get_git_sub_dir.py path/to/sub/dir <RECURSIVE>

Just to clarify some of the great answers here, the steps outlined in many of the answers assume that you already have a remote repository somewhere.

Given: an existing git repository, e.g. [email protected]:some-user/full-repo.git, with one or more directories that you wish to pull independently of the rest of the repo, e.g. directories named app1 and app2

Assuming you have a git repository as the above...

Then: you can run steps like the following to pull only specific directories from that larger repo:

mkdir app1
cd app1
git init
git remote add origin [email protected]:some-user/full-repo.git
git config core.sparsecheckout true
echo "app1/" >> .git/info/sparse-checkout
git pull origin master

I had mistakenly thought that the sparse-checkout options had to be set on the original repository, but this is not the case: you define which directories you want locally, prior to pulling from the remote. The remote repo doesn't know or care about your only wanting to track a part of the repo.

Hope this clarification helps someone else.

here is what I do

git init
git sparse-checkout init
git sparse-checkout set "YOUR_DIR_PATH"
git remote add origin https://github.com/AUTH/REPO.git
git pull --depth 1 origin <SHA1_or_BRANCH_NAME>

Simple note

• sparse-checkout

• git sparse-checkout init many articles will tell you to set git sparse-checkout init --cone If I add --cone will get some files that I don't want.

• git sparse-checkout set "..." will set the .git\info\sparse-checkout file contents as ...

  Suppose you don't want to use this command. Instead, you can open the git\info\sparse-checkout and then edit.

Example

Suppose I want to get 2 folder^{full repo size>10GB↑ (include git)}, as below ^{total size < 2MB}

1. chrome/common/extensions/api
2. chrome/common/extensions/permissions

git init
git sparse-checkout init
// git sparse-checkout set "chrome/common/extensions/api/"
start .git\info\sparse-checkout   👈 open the "sparse-checkut" file

/* .git\info\sparse-checkout  for example you can input the contents as below 👇

git remote add origin https://github.com/chromium/chromium.git

// or
// git pull --depth 1 origin master

• partialclonefilter = blob:none

  I know to add this line because I know from: git clone --filter=blob:none it will write this line. so I imitate it.

git version: git version 2.29.2.windows.3

Here's a shell script I wrote for the use case of a single subdirectory sparse checkout

coSubDir.sh

localRepo=$1
remoteRepo=$2
subDir=$3


# Create local repository for subdirectory checkout, make it hidden to avoid having to drill down to the subfolder
mkdir ./.$localRepo
cd ./.$localRepo
git init
git remote add -f origin $remoteRepo
git config core.sparseCheckout true

# Add the subdirectory of interest to the sparse checkout.
echo $subDir >> .git/info/sparse-checkout

git pull origin master

# Create convenience symlink to the subdirectory of interest

I wrote a .gitconfig [alias] for performing a "sparse checkout". Check it out (no pun intended):

On Windows run in cmd.exe

git config --global alias.sparse-checkout "!f(){ [ $# -eq 2 ] && L=${1##*/} L=${L%.git} || L=$2; mkdir -p \"$L/.git/info\" && cd \"$L\" && git init --template= && git remote add origin \"$1\" && git config core.sparseCheckout 1; [ $# -eq 2 ] && echo \"$2\" >> .git/info/sparse-checkout || { shift 2; for i; do echo $i >> .git/info/sparse-checkout; done }; git pull --depth 1 origin master;};f"

Otherwise:

git config --global alias.sparse-checkout '!f(){ [ $# -eq 2 ] && L=${1##*/} L=${L%.git} || L=$2; mkdir -p "$L/.git/info" && cd "$L" && git init --template= && git remote add origin "$1" && git config core.sparseCheckout 1; [ $# -eq 2 ] && echo "$2" >> .git/info/sparse-checkout || { shift 2; for i; do echo $i >> .git/info/sparse-checkout; done }; git pull --depth 1 origin master;};f'

Usage:

# Makes a directory ForStackExchange with Plug checked out
git sparse-checkout https://github.com/YenForYang/ForStackExchange Plug

# To do more than 1 directory, you have to specify the local directory:
git sparse-checkout https://github.com/YenForYang/ForStackExchange ForStackExchange Plug Folder

The git config commands are 'minified' for convenience and storage, but here is the alias expanded:

# Note the --template= is for disabling templates.
# Feel free to remove it if you don't have issues with them (like I did)
# `mkdir` makes the .git/info directory ahead of time, as I've found it missing sometimes for some reason
f(){
	[ "$#" -eq 2 ] && L="${1##*/}" L=${L%.git} || L=$2;
	mkdir -p "$L/.git/info"
		&& cd "$L"
		&& git init --template=
		&& git remote add origin "$1"
		&& git config core.sparseCheckout 1;
	[ "$#" -eq 2 ]
		&& echo "$2" >> .git/info/sparse-checkout
		|| {
			shift 2;
			for i; do
				echo $i >> .git/info/sparse-checkout;
			done
		};
	git pull --depth 1 origin master;
};
f

Lots of great responses here, but I wanted to add that using the quotations around the directory names was failing for me on Windows Sever 2016. The files simply were not being downloaded.

Instead of

"mydir/myfolder"

I had to use

mydir/myfolder

Also, if you want to simply download all sub directories just use

git sparse-checkout set *

If you're actually ony interested in the latest revision files of a directory, Github lets you download a repository as Zip file, which does not contain history. So downloading is very much faster.

While I hate actually having to use svn when dealing with git repos :/ I use this all the time;

function git-scp() (
  URL="$1" && shift 1
  svn export ${URL/blob\/master/trunk}
)

This allows you to copy out from the github url without modification. Usage;

--- /tmp » git-scp https://github.com/dgraph-io/dgraph/blob/master/contrib/config/kubernetes/helm                                                                                                                  1 ↵

Lots of good ideas and scripts above. I could not help myself and combined them into a bash script with help and error checking:

#!/bin/bash

function help {
  printf "$1
Clones a specific directory from the master branch of a git repository.

Syntax:
  $(basename $0) [--delrepo] repoUrl sourceDirectory [targetDirectory]

If targetDirectory is not specified it will be set to sourceDirectory.
Downloads a sourceDirectory from a Git repository into targetdirectory.
If targetDirectory is not specified, a directory named after `basename sourceDirectory`
will be created under the current directory.

If --delrepo is specified then the .git subdirectory in the clone will be removed after cloning.


Example 1:
Clone the tree/master/django/conf/app_template directory from the master branch of
[email protected]:django/django.git into ./app_template:

\$ $(basename $0) [email protected]:django/django.git django/conf/app_template

\$ ls app_template/django/conf/app_template/
__init__.py-tpl  admin.py-tpl  apps.py-tpl  migrations  models.py-tpl  tests.py-tpl  views.py-tpl


Example 2:
Clone the django/conf/app_template directory from the master branch of
https://github.com/django/django/tree/master/django/conf/app_template into ~/test:

\$ $(basename $0) [email protected]:django/django.git django/conf/app_template ~/test

\$ ls test/django/conf/app_template/
__init__.py-tpl  admin.py-tpl  apps.py-tpl  migrations  models.py-tpl  tests.py-tpl  views.py-tpl

"
  exit 1
}

if [ -z "$1" ]; then help "Error: repoUrl was not specified.\n"; fi
if [ -z "$2" ]; then help "Error: sourceDirectory was not specified."; fi

if [ "$1" == --delrepo ]; then
  DEL_REPO=true
  shift
fi

REPO_URL="$1"
SOURCE_DIRECTORY="$2"
if [ "$3" ]; then
  TARGET_DIRECTORY="$3"
else
  TARGET_DIRECTORY="$(basename $2)"
fi

echo "Cloning into $TARGET_DIRECTORY"
mkdir -p "$TARGET_DIRECTORY"
cd "$TARGET_DIRECTORY"
git init
git remote add origin -f "$REPO_URL"
git config core.sparseCheckout true

echo "$SOURCE_DIRECTORY" > .git/info/sparse-checkout
git pull --depth=1 origin master

if [ "$DEL_REPO" ]; then rm -rf .git; fi

You can still use svn:

svn export https://admin@domain.com/home/admin/repos/finisht/static static --force

to "git clone" a subdirectory and then to "git pull" this subdirectory.

(It is not intended to commit&push.)

git init <repo>
cd <repo>
git remote add origin <url>
git config core.sparsecheckout true
echo "<path you want to clone>/*" >> .git/info/sparse-checkout
git pull --depth=1 origin <branch you want to fetch>

Example for cloning only Jetsurvey Folder from this repo

git init MyFolder
cd MyFolder 
git remote add origin [email protected]:android/compose-samples.git
git config core.sparsecheckout true
echo "Jetsurvey/*" >> .git/info/sparse-checkout
git pull --depth=1 origin main

• If you want to clone

  git clone --no-checkout <REPOSITORY_URL>
  cd <REPOSITORY_NAME>
  

  1. Now set the specific file / directory you wish to pull into the working-directory:

     git sparse-checkout set <PATH_TO_A_SPECIFIC_DIRECTORY_OR_FILE_TO_PULL>
     

  2. Afterwards, you should reset hard your working-directory to the commit you wish to pull. > For example, we will reset it to the default origin/master's HEAD commit.

     git reset --hard HEAD
     

• If you want to git init and then remote add

  git init
  git remote add origin <REPOSITORY_URL>
  

  1. Now set the specific file / directory you wish to pull into the working-directory:

     git sparse-checkout set <PATH_TO_A_SPECIFIC_DIRECTORY_OR_FILE_TO_PULL>
     

  2. Pull the last commit:

     git pull origin master
     

> NOTE: > > If you want to add another directory/file to your working-directory, you may do it like so: > > git sparse-checkout add <PATH_TO_ANOTHER_SPECIFIC_DIRECTORY_OR_FILE_TO_PULL> > > > If you want to add all the repository to the working-directory, do it like so: > > git sparse-checkout add * > > > If you want to empty the working-directory, do it like so: > > git sparse-checkout set empty >

If you want, you can view the status of the tracked files you have specified, by running:

git status

If you want to exit the sparse mode and clone all the repository, you should run:

git sparse-checkout set *
git sparse-checkout set init
git sparse-checkout set disable

I don't know if anyone succeeded pulling specific directory, here is my experience: git clone --filter=blob:none --single-branch <repo>, cancel immediately while downloading objects, enter repo, then git checkout origin/master <dir>, ignore errors (sha1), enter dir, repeat checkout (using new dir) for every sub-directory. I managed to quickly get source files in this way

It worked for me- (git version 2.35.1)

git init
git remote add origin <YourRepoUrl>
git config core.sparseCheckout true
git sparse-checkout set <YourSubfolderName>
git pull origin <YourBranchName>

So i tried everything in this tread and nothing worked for me ... Turns out that on version 2.24 of Git (the one that comes with cpanel at the time of this answer), you don't need to do this

echo "wpm/*" >> .git/info/sparse-checkout

all you need is the folder name

wpm/*

So in short you do this

git config core.sparsecheckout true

you then edit the .git/info/sparse-checkout and add the folder names (one per line) with /* at the end to get subfolders and files

wpm/*

Save and run the checkout command

git checkout master

The result was the expected folder from my repo and nothing else Upvote if this worked for you
