Powershell 在保持文件夹结构的同时复制PDF

因此，我试图复制所有文件夹，并保留只包含pdf的结构。我不确定是否有办法做到这一点，我已经设法让一些脚本工作

但是，当我运行它时，它会复制所有文件夹，即使其中没有PDF。我还注意到，我的脚本无法检查文件夹并在下一个目录中创建。例如：

C:\temp复制一次显示C:\temp.
如果我再次运行脚本，它现在显示C:\temp\temp

下面是我的代码：

$Criteria = *.pdf
$Trial = c:\temp\folders.txt
$Server = \\file
$Path = homedrives\home
$des = $Path
$safe = Get-Content $Trial
$safe | ForEach-Object {
    #find drive-delimeter
    $first = $_.IndexOf("\\");
    if ($first -eq 1) {
        #stripe it
        $newdes = Join-Path -Path $des -ChildPath @($_.Substring(0,1)+$_.Substring(2))[0]    
    } else {
        $newdes = Join-Path -Path $des -ChildPath $_
    }
    $err = 0
    $fr = 0
    $folder = Split-Path -Path $newdes -Parent
    #check if folder exists"
    $void = Get-Item $folder -ErrorVariable err -ErrorAction SilentlyContinue
    if ($err.Count -ne 0) {
        #create when it doesn't
        $void = New-Item -Path $folder -ItemType Directory -Force
    }  
    #$void = Copy-Item -Path $_ -destination $newdes  -Force -Verbose
    $void = Copy-Item -Path $_ -destination $newdes -Filter $Criteria -Recurse -Force  -ErrorVariable fr -ErrorAction SilentlyContinue
    $CR = "`r`n"
    $RR = $fr[0].CategoryInfo.TargetName.ToString()
   "List of PDF's that Failed To Copy" + $CR + "--------------------------------------------------------------" + $CR + $RR | Out-file -Append $Er
    Write-Host $_
}
Write-Host $newdes

---

好的，看来我已经破解了它，为了将来的参考，我的代码实际上使用用户输入来确定位置，然后选择用户请求的标准，然后只复制定义了扩展名的文件。它在不复制的情况下复制文件夹结构，尽管windows的文件名限制仍然存在，但会生成一个错误日志，显示无法复制的文件。谢谢你在这件事上的帮助
