示例：在中创建新文件夹Application Data

Question

在我的用户文件夹中，( C:\Users\user) 有一堆符号链接不会显示在文件资源管理器中，即使启用了 show>hidden 也是如此。我之所以注意到它们，是因为我在 VS Code 中打开了我的文件夹。如果我尝试通过在文件资源管理器中输入其路径来打开一个文件夹，它会显示以下弹出窗口。

我可以Set-Location在管理员中对它们进行操作pwsh，但如果我尝试Get-ChildItem，它会说
Get-ChildItem: Access to the path 'C:\Users\user\Application Data' is denied.
在管理员中cmd，dir输入它们会返回

 Volume in drive C is Windows
 Volume Serial Number is B426-88EF

 Directory of C:\Users\user\Application Data

File Not Found

以下是链接列表：

Application Data
Cookies
Local Settings
My Documents
NetHood
PrintHood
Recent
SendTo
Start Menu
Templates

（我还没有尝试打开所有这些，只打开了几个。如果我应该尝试某个特定的，请在评论中说出来）

...所以我的问题是：这些是怎么回事？它们是一些遗留问题吗？超级管理员权限是怎么回事？

微软在 Windows Vista/Windows Server 2008 中引入了新的文件夹结构，出于向后兼容性的原因，他们决定用连接点替换所有已移动的文件夹。

连接点的文件夹和文件无法列出，您只能使用其完整路径直接访问或创建/保存/编辑文件或文件夹。原因是连接点的 ACL。

示例：在中创建新文件夹Application Data

New-Item "$Env:USERPROFILE\Application Data\test" -Type Directory

创建文件夹%AppData%\test

示例：列出现有子目录中的目录Application Data

Get-ChildItem "$Env:USERPROFILE\Application Data\Microsoft"

列表%AppData%\Microsoft

示例：我的电脑上的其他连接点和符号链接

以下 PS 命令将C:\Users\All Users递归列出所有连接点以及符号链接（如，可以无权限问题进行访问）。

Get-ChildItem C:\ -Force -Attributes ReparsePoint+System+Hidden -Recurse | 
    ? { $_.FullName -notlike 'C:\Windows.old*' } | Select LinkType, FullName, Target
