PowerShell script to copy a SharePoint Document Library to a Local Path

I cannot take credit for this awesome script, it was done by JBMurphy.com

Function JBM-SharePoint-CopyDocumentLibraryLocal {

PARAM([Parameter(Mandatory=$true)]$SiteURL,

    [Parameter(Mandatory=$true)]$DocumentLibrary,

    [Parameter(Mandatory=$true)]$Destination)

$spWeb = Get-SPWeb -Identity http://$SiteURL

$list = $spWeb.Lists[$DocumentLibrary]

foreach ($listItem in $list.Items)

{

    $DestinationPath = $listItem.Url.replace("$DocumentLibrary","$Destination").Replace("/","\")

    write-host "Downloading $($listItem.Name) -> $DestinationPath"

    if (!(Test-Path -path $(Split-Path $DestinationPath -parent)))

    {

        write-host "Createing $(Split-Path $DestinationPath -parent)"

        $dest = New-Item $(Split-Path $DestinationPath -parent) -type directory

    }

    $binary=$spWeb.GetFile($listItem.Url).OpenBinary()

    $stream = New-Object System.IO.FileStream($DestinationPath), Create

    $writer = New-Object System.IO.BinaryWriter($stream)

    $writer.write($binary)

    $writer.Close()

}

$spWeb.Dispose()
