Raw 链接直接下载</h4><ol><li><strong>打开文件页面</strong>：在仓库中定位到目标文件（如 <code>README.md</code>、<code>config.yml</code>）。</li><li><strong>点击 Raw</strong>：右上角显示 <strong>Raw</strong> 按钮，点击后文件内容以纯文本或二进制流形式呈现。</li><li><strong>另存为</strong>：浏览器中右键 → “另存为”（或快捷键 <code>Ctrl+S</code> / <code>⌘S</code>），选择本地目录即可。</li></ol><blockquote><p><strong>注意</strong>：</p><ul><li><strong>文件类型</strong>：若是图片／二进制，Raw 页面会直接显示，另存时可保持原格式。</li><li><strong>大文件限制</strong>：浏览器下载大于 100 MB 文件可能失败，建议改用CLI或ZIP方式。</li></ul></blockquote><ul><li><ul><li>搜索 “GitHub Raw 下载 文件 方法”</li></ul></li><li><strong>中国大陆访问</strong>：配合 FastGit 镜像 Raw 链接：</li></ul>

DownGit 在线工具</h4><p>DownGit 是社区维护的单/多文件及子目录打包工具。</p><ol><li>访问 DownGit：https://minhaskamal.github.io/DownGit/#/home</li><li>将 GitHub 文件或文件夹页面 URL 粘贴到输入框。</li><li>自定义分支（<code>master</code>/<code>main</code> 等）与下载格式（ZIP）后，点击 <strong>Download</strong>。</li></ol><blockquote><p><strong>优势</strong>：</p><ul><li>可批量下载整个子目录</li><li>支持自定义 URL 前缀（结合 FastGit 镜像）</li><li>直观，无需本地安装</li></ul></blockquote>

<hr><h4>3. 脚本/CLI 自动化下载</h4><p>对于需要批量或定时获取文件场景，可使用脚本配合 GitHub API 或 <code>curl</code>/<code>wget</code>。</p>

</blockquote><hr><h3> 下载子目录 & 子模块</h3><p>大型 monorepo 或多语言项目中，下载整库不一定高效。以下方法可仅取所需模块。</p><h4>1. <code>git sparse-checkout</code></h4><p>从 Git 2.25+ 开始支持。仅检出指定路径，节省空间与带宽。</p>
<pre style="white-space: pre !important; word-wrap: normal !important; overflow-x: auto !important"><code class="prism language-bash"><span class="token comment"># 初始化仓库（空克隆）</span>

<pre style="white-space: pre !important; word-wrap: normal !important; overflow-x: auto !important"><code class="prism language-bash"><span class="token comment"># 添加子模块</span>

<ul><li><strong>子模块</strong>：保留子仓库历史，可独立更新</li><li><strong>子树</strong>：将子项目合并到主仓库，管理更简单</li></ul><hr><h3> 下载完整仓库</h3><h4>1. 原生 <code>git clone</code></h4>
<pre style="white-space: pre !important; word-wrap: normal !important; overflow-x: auto !important"><code class="prism language-bash"><span class="token function">git</span> clone https://github.com/用户名/仓库名.git

<h5>GEO 加速</h5><ul><li><p><strong>FastGit</strong>：</p> <pre style="white-space: pre !important; word-wrap: normal !important; overflow-x: auto !important"><code class="prism language-bash"><span class="token function">git</span> clone https://hub.fastgit.org/用户名/仓库名.git</code></pre> </li><li><p><strong>Gitee 镜像</strong>：在 Gitee 上搜索并 Clone 国内镜像</p></li></ul><p><img src="https://i-blog.csdnimg.cn/blog_migrate/94fd99f44452bc854b126f63df744dad.png"></p><hr><h4>2. GitHub CLI</h4><p>GitHub 官方 CLI (<code>gh</code>) 提供额外功能。</p>
<pre style="white-space: pre !important; word-wrap: normal !important; overflow-x: auto !important"><code class="prism language-bash"><span class="token comment"># 安装 gh：https://cli.github.com/</span>
gh auth login <span class="token comment"># 登录并授权</span>
