Download multiple SharePoint files using PNP Powershell

Question

I am looking to move all files from a SharePoint location to a folder on the C drive. I am able to move one specified file but not all of them. I can see how you can move files from one SharePoint location to another but it is possible to do what I require? Be aware that this script will be put on a scheduled task and the files will have new names each day so the filenames cannot be specified. Move all files from a SharePoint location to a folder on the C drive?

Hi Alexandra Smith,   You can download multiple files in SharePoint library using below code
$webUrl =  "https:// .sharepoint.com" ;   $listUrl =  "Shared%20Documents" ;   $destination =  "E:\Check"         Connect-PnPOnline -Url $webUrl   $web = Get-PnPWeb   $list = Get-PNPList -Identity $listUrl      function ProcessFolder($folderUrl, $destinationFolder) {          $folder = Get-PnPFolder -RelativeUrl $folderUrl       $tempfiles = Get-PnPProperty -ClientObject $folder -Property Files              if  (!(Test-Path -path $destinationfolder)) {           $dest = New-Item $destinationfolder -type directory        }          $total = $folder.Files.Count       For ($i = 0; $i -lt $total; $i++) {           $file = $folder.Files[$i]                      Get-PnPFile -ServerRelativeUrl $file.ServerRelativeUrl -Path $destinationfolder -FileName $file.Name -AsFile       }   }      function ProcessSubFolders($folders, $currentPath) {       foreach ($folder in $folders) {           $tempurls = Get-PnPProperty -ClientObject $folder -Property ServerRelativeUrl               #Avoid Forms folders             if  ($folder.Name -ne  "Forms" ) {               $targetFolder = $currentPath + "" + $folder.Name;               ProcessFolder $folder.ServerRelativeUrl.Substring($web.ServerRelativeUrl.Length) $targetFolder                $tempfolders = Get-PnPProperty -ClientObject $folder -Property Folders               ProcessSubFolders $tempfolders $targetFolder           }       }   }      #Download root files    ProcessFolder $listUrl $destination +  ""     #Download files in folders    $tempfolders = Get-PnPProperty -ClientObject $list.RootFolder -Property Folders   ProcessSubFolders $tempfolders $destination +  ""

Hi.. Thank you for getting back to me.  Unfortunately, when I run the script, I get the following error:   Get-PnPFile : The WriteObject and WriteError methods cannot be called from outside the overrides of the BeginProcessing, ProcessRecord, and EndProcessing methods, and they can only be called from within the same thread. Validate that the cmdlet makes these calls correctly, or contact Microsoft Customer Support Services.   Can you help with this please?  Do you now what it is?
