Once Git LFS is installed, you need to associate it with a large file in your repository.

If there are existing files in your repository that you'd like to use GitHub with, you need to first remove them from the repository and then add them to Git LFS locally. For more information, see "Moving a file in your repository to Git LFS."

  1. Open TerminalTerminalGit Bash.

  2. Change your current working directory to an existing repository you'd like to use with Git LFS.

  3. To associate a file type in your repository with Git LFS, enter git lfs track followed by the name of the file extension you want to automatically upload to Git LFS.

    For example, to associate a .psd file, enter the following command:

    git lfs track "*.psd"
    Adding path *.psd
    

    Every file type you want to associate with Git LFS will need to be added with git lfs track. This command amends your repository's .gitattributes file and associates large files with Git LFS.

    Tip: We strongly suggest that you commit your local .gitattributes file into your repository. Relying on a global .gitattributes file associated with Git LFS may cause conflicts when contributing to other Git projects.

  4. Add a file to the repository matching the extension you've associated:

    git add path/to/file.psd
    
  5. Commit the file and push it to GitHub:

    git commit -m "add file.psd"
    git push origin master
    

    You should see some diagnostic information about your file upload:

    Sending file.psd
    44.74 MB / 81.04 MB  55.21 % 14s
    64.74 MB / 81.04 MB  79.21 % 3s
