无法删除14天以前的zip文件夹

Question

我无法从目录中删除超过14天的zip文件夹。我的其余部分工作正常，但以下代码块失败：

它没有抛出任何错误，路径已经过检查，但是，我将旧文件放入其中以查看它们是否被清除无效。它打印文件夹路径存在的语句，但不删除文件夹中的任何内容。

if (!(Test-Path $folderpath)) {
    New-Item -ItemType Directory -Path $folderpath
    Write-Host "$folderpath created"
} else {
    Write-Host "$folderpath already exists, will remove old items"
    $HowOld = -14
    Get-ChildItem $Path -Recurse |
        where {$_.LastWriteTime -lt (Get-Date).AddDays($HowOld) -and -not $_.PSIsContainer} |
        % {Remove-Item $_.FullName -Force -WhatIf}
}

以下是完整性的完整脚本：
