PowerShell 重命名文件夹及删除空文件夹

数据来源 $urldata 中的倒数第2列（子文件夹名称列）包含 /、\ 等特殊字符

某个文件夹重命名脚本

 foreach ($i in 0..100) {
    # 提取路径部分
    $basePath = ($urldata[$i].split("`t")[-1]).trim()
    $subPath = ($urldata[$i].split("`t")[-2].replace('"', '')).trim()

    # 组合完整路径
    $fullPath = "$basePath/$subPath"

    # 替换字符以生成重命名路径
    $renamePath = $subPath -replace '/', '__' -replace '\\', '_、' -replace ':', '_：'
    $renamePath = "$basePath/$renamePath"
    if ($fullPath -eq $renamePath) {continue}
    if (Test-Path $fullPath) {
        # 创建文件夹
        New-Item -Path $renamePath -ItemType Directory -Force  # 确保目录存在

        # 移动文件
        Move-Item "$fullPath/*" -Destination $renamePath -Force  # 确保强制移动

        # 删除原文件夹
       Remove-Item -Path $fullPath -Recurse -Force  # 确保递归删除

        # 输出重命名路径以供检查
        Write-Host "Rename Path: $renamePath, del Path: $fullPath"
    } else {

	   $oldPath="Y:/$($renamePath.replace('__','_'))"
       $newPath="Y:/$renamePath"
	   if(Test-Path $oldPath){   rename-item  $oldPath $newPath }

       Write-Host "Path does not exist: $fullPath, 修改文件夹 $oldPath 为 $newPath"  # 如果路径不存在，输出提示
    }
}

递归查找当前文件夹下的子文件夹，

Get-ChildItem -Recurse | Where-Object { $_.psiscontainer -and ($_.GetFileSystemInfos().Count -eq 0) } | ForEach-Object { Remove-Item $_;Write-Host "文件夹 $_ 已删除" }

PS, 对 PowerShell 中的 Get-ChildItem 帮助的理解感到有些疑惑。

`Get-ChildItem` doesn't display empty directories. When a `Get-ChildItem` command includes the Depth or
     Recurse parameters, empty directories aren't included in the output.
