通常删除文件夹可以在UI界面操作比较方面，但是如果想快速的删除文件夹以及其child folder，该如何操作呢？

解决方案：本文将介绍如何使用PnP PowerShell脚本删除SharePoint文档库中的文件夹：第一步是通过运行cmdlet: Connect PnPOnline来完成连接到您的SharePoint Online网站；连接后，可以通过运行命令删除文件夹：Remove PnPFolder。

首先，将要删除的文件夹和子文件夹保存到csv文件中，如下所示：

执行PnP Powershell，删除上述文件夹和子文件夹，脚本如下所示：

$SiteURL = "https://byrondemo.sharepoint.com/sites/Project"
$CSVFilePath = "C:\Users\Byron\Desktop\BulkDeleteFolders.csv"
Connect-PnPOnline -Url $SiteURL -Interactive
$CSVFile = Import-CSV $CSVFilePath | Sort-Object ParentFolderSiteRelativeURL -Descending
ForEach($Row in $CSVFile)
{
    Try {
        $Folder  = Get-PnPFolderItem -FolderSiteRelativeUrl $Row.ParentFolderSiteRelativeURL -ItemName $Row.FolderName 
        If($Folder -ne $Null)
        {
            Write-Host -f Yellow "Deleting Folder '$($Row.FolderName)' from $($Row.ParentFolderSiteRelativeURL)..."
            Empty-PnPFolder $Folder
            Remove-PnPFolder -Name $Row.FolderName -Folder $Row.ParentFolderSiteRelativeURL -Recycle -Force
            Write-host -f Green "`tFolder '$($Row.FolderName)' Deleted Successfully!"
        }
        Else
        {
            Write-Host "Folder '$($Row.FolderName)' doesn't exists at $($Row.ParentFolderSiteRelativeURL)" -ForegroundColor Yellow
        }
    }
    Catch {
        write-host -f Red "`tError:" $_.Exception.Message
    }
}

如果预将文件和文件夹全部删除，那么命令为：

$SiteURL = "https://byrondemo.sharepoint.com/sites/Project"
$CSVFilePath = "C:\Users\Byron\Desktop\BulkDeleteFolders.csv"
Function Empty-PnPFolder($Folder)
{
    If($Folder.Context.Web.ServerRelativeUrl -eq "/")
    {
        $FolderSiteRelativeURL = $Folder.ServerRelativeUrl
    }
    Else
    {       
        $FolderSiteRelativeURL = $Folder.ServerRelativeUrl.Replace($Folder.Context.Web.ServerRelativeURL,[string]::Empty)
    }
    $Files = Get-PnPFolderItem -FolderSiteRelativeUrl $FolderSiteRelativeURL -ItemType File
    ForEach ($File in $Files)
    {
        Remove-PnPFile -ServerRelativeUrl $File.ServerRelativeURL -Force -Recycle
        Write-Host -f Green ("`tDeleted File: '{0}' at '{1}'" -f $File.Name, $File.ServerRelativeURL)       
    }
    $SubFolders = Get-PnPFolderItem -FolderSiteRelativeUrl $FolderSiteRelativeURL -ItemType Folder
    Foreach($SubFolder in $SubFolders)
    {
        If(($SubFolder.Name -ne "Forms") -and (-Not($SubFolder.Name.StartsWith("_"))))
        {
            Empty-PnPFolder -Folder $SubFolder
            Remove-PnPFolder -Name $SubFolder.Name -Folder $FolderSiteRelativeURL -Force -Recycle
            Write-Host -f Green ("`tDeleted Folder: '{0}' at '{1}'" -f $SubFolder.Name, $SubFolder.ServerRelativeURL)
        }
    }
}
