这招对我很管用:

Remove-Item C:\folder_name -Force -Recurse

$LogPath = "E:\" # Your local of directories
$Folders = Get-Childitem $LogPath -dir -r | Where-Object {$_.name -like "*grav*"} # Your keyword name directories

foreach ($Folder in $Folders) 
{
    $Item =  $Folder.FullName
    Write-Output $Item
    Remove-Item $Item -Force -Recurse -ErrorAction SilentlyContinue
}

Remove-Item -LiteralPath "foldertodelete" -Force -Recurse

或者，用更短的版本

rm /path -r -force

简而言之，我们可以使用rm -r -fo {folderName}递归地删除文件夹(删除里面的所有文件和文件夹)并强制

下面是Michael Freidgeim答案的一个可复制粘贴的实现

function Delete-FolderAndContents {
    # http://stackoverflow.com/a/9012108

    param(
        [Parameter(Mandatory=$true, Position=1)] [string] $folder_path
    )

    process {
        $child_items = ([array] (Get-ChildItem -Path $folder_path -Recurse -Force))
        if ($child_items) {
            $null = $child_items | Remove-Item -Force -Recurse
        }
        $null = Remove-Item $folder_path -Force
    }
}

要删除没有文件夹的内容，您可以使用以下方法:

Remove-Item "foldertodelete\*" -Force -Recurse
