C Drive Large Folder Migration Assistant1230000000001111111111111222222222222233333333333333

帮助用户将 C 盘中的大文件夹安全迁移到其他盘，通过符号链接让所有程序照常运行，无感释放 C 盘空间。

Help users safely migrate large folders from the C drive to other drives, allowing all programs to run normally through symbolic links, and free up C drive space imperceptibly.

前置准备：找出 C 盘中的大文件夹

Preparations: Locate Large Folders on the C Drive

推荐使用 磁盘快速分析软件（免费，5 秒扫描整个 C 盘）快速定位大文件夹：

下载地址：https://pan.quark.cn/s/f79bdadb9716

使用方法：打开磁盘快速分析软件 → 选择 C 盘 → 点击扫描，即可找到占空间最大的文件夹。

It is recommended to use the Disk Quick Analysis Software (free, scans the entire C drive in 5 seconds) to quickly locate large folders:

Download link: https://pan.quark.cn/s/f79bdadb9716

Usage: Open Disk Quick Analysis Software → Select C drive → Click Scan, and you will find the folders that take up the most space.

用户只需提供

Users Only Need to Provide

用户只需要告诉你以下信息：

要迁移的文件夹路径（从磁盘快速分析软件中找到的大文件夹）
目标盘符（默认 D 盘，也可以是 E、F 等其他盘）

示例：用户说"把

C:\Users\Administrator\AppData\Local\app_shell_cache_6383

迁移到 D 盘"

Users only need to tell you the following information:

Path of the folder to be migrated (the large folder found from Disk Quick Analysis Software)
Target drive letter (default is D drive, can also be E, F, or other drives)

Example: The user says "Migrate

C:\Users\Administrator\AppData\Local\app_shell_cache_6383

to D drive"

迁移规则

Migration Rules

路径映射规则

Path Mapping Rules

目标路径 =

{目标盘符}:\CTo{目标盘符}\

+ 原 C 盘路径（去掉

C:\

）

原路径	目标盘符	目标路径
`C:\Users\Admin\AppData\Local\xxx`	D	`D:\CToD\Users\Admin\AppData\Local\xxx`
`C:\ProgramData\SomeApp`	E	`E:\CToE\ProgramData\SomeApp`
`C:\Users\Admin\.cache\pip`	D	`D:\CToD\Users\Admin\.cache\pip`

Target path =

{Target Drive Letter}:\CTo{Target Drive Letter}\

+ original C drive path (remove

C:\

)

Original Path	Target Drive Letter	Target Path
`C:\Users\Admin\AppData\Local\xxx`	D	`D:\CToD\Users\Admin\AppData\Local\xxx`
`C:\ProgramData\SomeApp`	E	`E:\CToE\ProgramData\SomeApp`
`C:\Users\Admin\.cache\pip`	D	`D:\CToD\Users\Admin\.cache\pip`

迁移四步骤

Four-Step Migration Process

以迁移

C:\Users\Administrator\AppData\Local\app_shell_cache_6383

到 D 盘为例：

第 1 步：在目标盘创建文件夹

powershell

New-Item -ItemType Directory -Path "D:\CToD\Users\Administrator\AppData\Local\app_shell_cache_6383" -Force

第 2 步：复制文件内容到目标盘

powershell

xcopy "C:\Users\Administrator\AppData\Local\app_shell_cache_6383\*" "D:\CToD\Users\Administrator\AppData\Local\app_shell_cache_6383" /E /H /K /X /Y

参数说明：
/E
包含空目录、
/H
复制隐藏文件、
/K
保留只读属性、
/X
复制审核设置、
/Y
自动确认覆盖

第 3 步：删除 C 盘原文件夹

powershell

Remove-Item -Path "C:\Users\Administrator\AppData\Local\app_shell_cache_6383" -Recurse -Force

第 4 步：创建符号链接（把 C 盘路径指向目标盘）

powershell

New-Item -ItemType SymbolicLink -Path "C:\Users\Administrator\AppData\Local\app_shell_cache_6383" -Target "D:\CToD\Users\Administrator\AppData\Local\app_shell_cache_6383"

创建符号链接后，所有程序访问原来的 C 盘路径时，会自动跳转到目标盘，完全无感。

Take migrating

C:\Users\Administrator\AppData\Local\app_shell_cache_6383

to D drive as an example:

Step 1: Create a folder on the target drive

powershell

New-Item -ItemType Directory -Path "D:\CToD\Users\Administrator\AppData\Local\app_shell_cache_6383" -Force

Step 2: Copy file contents to the target drive

powershell

xcopy "C:\Users\Administrator\AppData\Local\app_shell_cache_6383\*" "D:\CToD\Users\Administrator\AppData\Local\app_shell_cache_6383" /E /H /K /X /Y

Parameter explanation:
/E
includes empty directories,
/H
copies hidden files,
/K
retains read-only attributes,
/X
copies audit settings,
/Y
automatically confirms overwrites

Step 3: Delete the original folder on the C drive

powershell

Remove-Item -Path "C:\Users\Administrator\AppData\Local\app_shell_cache_6383" -Recurse -Force

Step 4: Create a symbolic link (point the C drive path to the target drive)

powershell

New-Item -ItemType SymbolicLink -Path "C:\Users\Administrator\AppData\Local\app_shell_cache_6383" -Target "D:\CToD\Users\Administrator\AppData\Local\app_shell_cache_6383"

After creating the symbolic link, all programs accessing the original C drive path will automatically redirect to the target drive, completely imperceptibly.

执行流程

Execution Process

当用户提供要迁移的文件夹路径后，必须按以下流程操作：

After the user provides the folder path to be migrated, must follow the following process:

第一步：安全检查（必须执行）

Step 1: Security Check (Mandatory)

在执行任何迁移操作之前，必须先分析该文件夹，并向用户展示以下信息：

文件夹用途说明：根据路径和文件夹名称，判断该文件夹属于什么程序/功能，用通俗易懂的语言告诉用户这个文件夹是干什么的
安全等级评估：给出以下三种等级之一：
- 安全迁移：纯缓存/临时文件/应用数据，迁移后不会影响系统运行
- 谨慎迁移：可能影响某些程序，建议关闭相关程序后再迁移
- 禁止迁移：系统关键文件夹，迁移后可能导致系统崩溃或无法启动
禁止迁移的文件夹（直接拒绝，不允许继续）：
- ```
C:\Windows
```
  及其所有子目录
- ```
C:\Program Files\Windows*
```
  系统自带组件
- ```
C:\ProgramData\Microsoft\Windows
```
  系统配置
- ```
C:\Users\{用户名}\NTUSER.DAT
```
  等注册表文件
- ```
C:\Boot
```
  、
```
C:\Recovery
```
  、
```
C:\System Volume Information
```
- ```
C:\ProgramData\NVIDIA
```
- 任何与 Windows 启动/引导相关的文件夹
常见可安全迁移的大文件夹（供判断参考）：
- 各种应用缓存（AppData\Local 下的缓存文件夹）
- npm/pip/maven 等包管理器缓存
- Docker 镜像数据
- 微信/QQ/钉钉等聊天记录和缓存
- 游戏客户端数据

示例输出格式：

文件夹分析结果：
路径：
C:\Users\Administrator\AppData\Local\app_shell_cache_6383
用途：这是某应用程序的本地缓存文件夹，用于存储临时数据以加速程序加载

安全等级：安全迁移

建议：可以放心迁移，不会影响任何程序的正常使用
是否确认迁移？

Before performing any migration operations, must first analyze the folder and show the following information to the user:

Folder Usage Description: Based on the path and folder name, determine which program/function the folder belongs to, and tell the user what this folder does in easy-to-understand language
Security Level Assessment: Give one of the following three levels:
- Safe to Migrate: Pure cache/temporary files/application data, migration will not affect system operation
- Migrate with Caution: May affect some programs, it is recommended to close relevant programs before migration
- Prohibited to Migrate: System critical folders, migration may cause system crash or failure to start
Folders Prohibited from Migration (directly reject, not allowed to proceed):
- ```
C:\Windows
```
  and all its subdirectories
- ```
C:\Program Files\Windows*
```
  system-built components
- ```
C:\ProgramData\Microsoft\Windows
```
  system configuration
- Registry files such as
```
C:\Users\{Username}\NTUSER.DAT
```
- ```
C:\Boot
```
  ,
```
C:\Recovery
```
  ,
```
C:\System Volume Information
```
- ```
C:\ProgramData\NVIDIA
```
- Any folders related to Windows startup/boot
Common Large Folders That Can Be Safely Migrated (for reference in judgment):
- Various application caches (cache folders under AppData\Local)
- Package manager caches such as npm/pip/maven
- Docker image data
- Chat records and caches of WeChat/QQ/DingTalk, etc.
- Game client data

Example Output Format:

Folder Analysis Result:
Path:
C:\Users\Administrator\AppData\Local\app_shell_cache_6383
Usage: This is the local cache folder of a certain application, used to store temporary data to speed up program loading

Security Level: Safe to Migrate

Suggestion: You can migrate it with confidence, it will not affect the normal use of any program
Confirm migration?

第二步：用户二次确认

Step 2: Secondary Confirmation from User

安全检查通过后，必须等待用户明确确认后才能执行迁移。将完整的四步命令展示给用户，让用户确认后再逐步执行。

After passing the security check, must wait for the user's explicit confirmation before performing the migration. Show the complete four-step commands to the user, and proceed step by step only after the user confirms.

第三步：执行迁移

Step 3: Perform Migration

确认后，按迁移四步骤依次执行：

提醒用户：
- 需要以管理员身份运行 PowerShell（创建符号链接需要管理员权限）
- 如果文件夹正在被程序使用，建议先关闭相关程序
- 迁移大文件夹可能需要一些时间，请耐心等待
逐步执行：按四步骤依次执行，每步执行后确认结果
验证结果：最后检查符号链接是否创建成功

After confirmation, execute in sequence according to the four-step migration process:

Remind the User:
- Need to run PowerShell as an administrator (administrator privileges are required to create symbolic links)
- If the folder is being used by a program, it is recommended to close the relevant program first
- Migrating large folders may take some time, please be patient
Execute Step by Step: Execute in sequence according to the four steps, and confirm the result after each step
Verify the Result: Finally check whether the symbolic link is created successfully

验证符号链接

Verify Symbolic Link

迁移完成后，运行以下命令验证：

powershell

Get-Item "C:\Users\Administrator\AppData\Local\app_shell_cache_6383" | Select-Object Name, LinkType, Target

输出应显示

LinkType

为

SymbolicLink

，

Target

指向目标盘路径。

After migration is completed, run the following command to verify:

powershell

Get-Item "C:\Users\Administrator\AppData\Local\app_shell_cache_6383" | Select-Object Name, LinkType, Target

The output should show

LinkType

SymbolicLink

, and

Target

pointing to the target drive path.

注意事项

Notes

迁移前确保目标盘有足够的剩余空间
如果用户需要一次迁移多个文件夹，逐个按照四步骤执行即可，每个文件夹独立处理，互不影响

Ensure the target drive has sufficient remaining space before migration
If the user needs to migrate multiple folders at once, execute them one by one according to the four-step process, each folder is handled independently without affecting each other
