今天在安装 ollama 时发现无法指定安装目录，而且它的命令行反馈内容很像 docker ，而且它下载的模型也是放在 C 盘，那么如果我 C 盘空间不足，就装不了 deepseek-r1:70b ，于是想起来之前安装 Docker 的时候也遇到过类似问题:
也是无法指定路径，导致 C 盘空间不足时制作容器失败，因此想试试看 ollama 安装能不能也这样玩，但是后来用不到就忘记了当初是怎么弄的了，刚刚翻了下硬盘，还好找到当初的安装过程记录文件，但是博客里面居然没有记录，于是写篇文章记录下：
mklink /J "C:\ProgramData\Docker" "E:\Studio\docker\images"
mklink /J "C:\Program Files\Docker" "D:\Program Files\Docker"看起来用的虚拟目录映射法搞定的。
PS E:\Studio\docker> echo "以下为重新设置安装目录后"
以下为重新设置安装目录后
PS E:\Studio\docker> docker info

补充： ollama 也用此法搞定了自定义安装路径以及模型安装路径。
