C盘空间清理方法 - 软链接迁移指南
通过将用户目录下的大型缓存目录迁移到其他盘（如D盘），可以有效释放C盘空间。
原理
Windows 支持两种目录链接方式：
- Junction (目录连接) - 兼容性好，支持跨分区
- Symbolic Link (符号链接) - 更灵活，需要管理员权限
本方案使用软链接将缓存目录从 C 盘指向 D 盘，应用程序仍按原路径访问，实际数据存储在 D 盘。
迁移步骤
1. 用户主目录下的目录
以下目录从 C:\Users\Administrator 迁移到 D:\Users\Administrator：
| 目录 | 说明 |
|---|---|
.android |
Android SDK 缓存 |
.bito |
Bito AI 工具缓存 |
.cache |
通用缓存目录 |
.cargo |
Rust Cargo 包缓存 |
.gradle |
Gradle 构建缓存 |
.m2 |
Maven 本地仓库 |
.npm |
npm 全局缓存 |
.bun |
bun 全局缓存 |
.rustup |
Rust 工具链 |
迁移命令：
batch
:: 创建 D 盘目标目录结构
mkdir D:\Users\Administrator
:: 1. .android 目录
## 使用powershell执行:
move C:\Users\Administrator\.android D:\Users\Administrator\.android
## 使用cmd执行
mklink /J C:\Users\Administrator\.android D:\Users\Administrator\.android
:: 2. .bito 目录
move C:\Users\Administrator\.bito D:\Users\Administrator\.bito
mklink /J C:\Users\Administrator\.bito D:\Users\Administrator\.bito
:: 3. .cache 目录
move C:\Users\Administrator\.cache D:\Users\Administrator\.cache
mklink /D C:\Users\Administrator\.cache D:\Users\Administrator\.cache
:: 4. .cargo 目录
move C:\Users\Administrator\.cargo D:\Users\Administrator\.cargo
mklink /D C:\Users\Administrator\.cargo D:\Users\Administrator\.cargo
:: 5. .gradle 目录
move C:\Users\Administrator\.gradle D:\Users\Administrator\.gradle
mklink /J C:\Users\Administrator\.gradle D:\Users\Administrator\.gradle
:: 6. .m2 目录
move C:\Users\Administrator\.m2 D:\Users\Administrator\.m2
mklink /D C:\Users\Administrator\.m2 D:\Users\Administrator\.m2
:: 7. .npm 目录
move C:\Users\Administrator\.npm D:\Users\Administrator\.npm
mklink /D C:\Users\Administrator\.npm D:\Users\Administrator\.npm
:: 8. .bun 目录
move C:\Users\Administrator\.bun D:\Users\Administrator\.bun
mklink /D C:\Users\Administrator\.bun D:\Users\Administrator\.bun
:: 9. .rustup 目录
move C:\Users\Administrator\.rustup D:\Users\Administrator\.rustup
mklink /D C:\Users\Administrator\.rustup D:\Users\Administrator\.rustup2. AppData\Local 目录下的目录
以下目录从 C:\Users\Administrator\AppData\Local 迁移到 D:\Users\Administrator\AppData\Local：
| 目录 | 说明 |
|---|---|
Yarn |
Yarn 包管理器缓存 |
npm-cache |
npm 缓存目录 |
pnpm-cache |
pnpm 缓存目录 |
迁移命令：
batch
:: 创建 D 盘目标目录结构
mkdir D:\Users\Administrator\AppData\Local
:: 1. Yarn 目录
move C:\Users\Administrator\AppData\Local\Yarn D:\Users\Administrator\AppData\Local\Yarn
mklink /D C:\Users\Administrator\AppData\Local\Yarn D:\Users\Administrator\AppData\Local\Yarn
:: 2. npm-cache 目录
move C:\Users\Administrator\AppData\Local\npm-cache D:\Users\Administrator\AppData\Local\npm-cache
mklink /D C:\Users\Administrator\AppData\Local\npm-cache D:\Users\Administrator\AppData\Local\npm-cache
:: 3. pnpm-cache 目录
move C:\Users\Administrator\AppData\Local\pnpm-cache D:\Users\Administrator\AppData\Local\pnpm-cache
mklink /D C:\Users\Administrator\AppData\Local\pnpm-cache D:\Users\Administrator\AppData\Local\pnpm-cache一键迁移脚本
