powershell - 使用 PowerShell 设置特殊文件夹的位置

Question

作为管理员，我想将特殊文件夹(文档、音乐、下载...)的默认位置更改为不同的路径。我可以手动执行此操作，但我想要一个 PowerShell 脚本来执行此操作。

是否有任何 PS 对象提供执行此操作的功能？我该怎么做？谢谢。

Answer 1

PowerShell 没有可让您开箱即用的 cmdlet(据我所知)，但您可以使用 P/Invoke 调用 SHSetKnownFolderPath shell 函数。我创建了一个名为 Set-KnownFolderPath 的包装函数来执行此操作:

<#
.SYNOPSIS
    Sets a known folder's path using SHSetKnownFolderPath.
.PARAMETER Folder
    The known folder whose path to set.
.PARAMETER Path
    The path.
#>
function Set-KnownFolderPath {
    Param (

public extern static int SHSetKnownFolderPath(ref Guid folderId, uint flags, IntPtr token, [MarshalAs(UnmanagedType.LPWStr)] string path);
'@
        $Type = Add-Type -MemberDefinition $Signature -Name 'KnownFolders' -Namespace 'SHSetKnownFolderPath' -PassThru
    }
    
    # Validate the path
    if (Test-Path $Path -PathType Container) {
        # Call SHSetKnownFolderPath
        return $Type::SHSetKnownFolderPath([ref]$KnownFolders[$KnownFolder], 0, 0, $Path)
    } else {
        throw New-Object System.IO.DirectoryNotFoundException "Could not find part of the path $Path."
    }
}

像这样使用它:

Set-KnownFolderPath -KnownFolder 'Desktop' -Path 'C:\'
