看一下这个博客:

做到这一点的方法是复制内置文件系统格式文件，对其进行修改以指示连接，然后使用Update-FormatData加载该文件:

从博客:

The file system formatting rules are in $pshome\FileSystem.Format.ps1xml. I copied this, then in the element [ViewDefinitions –> View –> TableControl –> TableRowEntries –> TableRowEntry –> TableColumnItems –> TableColumnItem] I changed the content of PropertyName with value of 'Mode' to the following:

<ScriptBlock> 
   "$($_.Mode)$(if($_.Attributes -band [IO.FileAttributes]::ReparsePoint)
{'J'})" </ScriptBlock> 

This does a bitwise AND on the DirectoryInfo object Attributes property ($_.Attributes) against the .Net System.IO.FileAttributes.ReparsePoint enum value. If the result is not zero, it displays a ‘J’ next to the other file mode attributes. Next, load the new formatting file like this:

 PS> Update-FormatData -PrependPath myFilesystem.format.ps1xml

The PrependPath parameter ensures that the new formatting file is loaded before the built-in formatting files.

Directory alink has a ‘J’ in the mode column, seems to work!

It's in the Mode column J for Junction.
