    I have been having problems downloading a file from a FTP site – it keeps on timing out. I am currently trying the following code:

    $downloadRequest = [Net.WebRequest]::Create($fileUrl)
    $downloadRequest.Method = [System.Net.WebRequestMethods+FTP]::DownloadFile
    $downloadRequest.Credentials = $credentials

    $downloadResponse = $downloadRequest.GetResponse()
    $sourceStream = $downloadResponse.GetResponseStream()
    $targetStream = [System.IO.File]::Create($localFilePath)
    $buffer = New-Object byte[] 10240
    while (($read = $sourceStream.Read($buffer, 0, $buffer.Length)) -gt 0)
    $targetStream.Write($buffer, 0, $read);


    I have changed both Timeout and ReadWriteTimeout values but this made no difference. Possibly a setting on the source server?

    Anyway – is there a way to resume the download once it has timed out?

    Not using that class, no. I'd –strongly– suggest you look at BITS, the Background Intelligent Transfer Service, and its associated PowerShell cmdlets. It's designed for this specific purpose.
