VS2017如何放到别的盘

最近收到不少朋友私信，说电脑C盘总被VS2017占满空间。今天咱们就来唠唠这事儿——其实换个安装路径没想象中复杂，但有几个关键步骤要特别注意，我把自己折腾两小时的经验都整理在这儿了。

安装时的路径选择

哎，C盘又红了！这时候千万别急着点"下一步"。安装向导进行到工作负载选择界面时，仔细看右下角有个"安装位置"的齿轮图标。点进去后你会发现三个路径设置：

  • 主程序安装路径（建议保持默认）
  • 下载缓存路径（这个必须改到其他盘）
  • 共享组件路径（建议与缓存路径同盘）

这里有个坑要注意：下载缓存占空间最大，动辄20GB起步。记得把第二个路径改成类似"D:\VS2017Cache"这样的位置，共享组件可以设为"D:\VSShared"。

已安装的迁移方案

要是已经装在C盘了也别慌，咱们还有补救办法。先在控制面板完整卸载VS2017，别用第三方卸载工具，容易残留注册表信息。重新安装时按上述方法设置路径就行。

特殊需求处理

遇到需要保留原有配置的情况，可以试试这招：

  1. 把整个"C:\Program Files (x86)\Microsoft Visual Studio"文件夹剪切到新位置
  2. 用管理员权限打开cmd
  3. 输入mklink /J "C:\Program Files (x86)\Microsoft Visual Studio" "D:\NewLocation"

这样创建目录联接后，系统会认为程序还在C盘，实际文件都存放在新位置。

避坑指南

  • 移动前备份项目文件
  • 不要直接修改安装目录权限
  • 遇到错误代码先查微软官方文档

最后唠叨一句：完成迁移后记得运行磁盘清理工具，把原先的安装残留清干净。有次我偷懒没清理，结果系统更新时又自动在C盘生成临时文件，白折腾一场...
