{
    [long]$FolderSize = 0
 
    foreach ($File in $Folder.Files)
    {
   #Get File Size
        $FolderSize += $file.TotalLength;
   
  #Get the Versions Size
        foreach ($FileVersion in $File.Versions)
        {
            $FolderSize += $FileVersion.Size

    }
    return $FolderSize

$SiteURL = "http://sharepoint.company.com/"
$Site = new-object Microsoft.SharePoint.SPSite($SiteURL)
