This isn't quite what you are after, but it's not far off, and I am sure you'll be able to modify it for your needs (such as add a for-each loop for each file in a folder. This is a modified version of the solution found here I use, which has logging, the ability to use SSL and (of course) be parametrised:

[CmdletBinding()]
param(
  [Parameter(Mandatory=$true)]
  [String]$Username,
  [Parameter(Mandatory=$true)]
  [String]$Password,
  [Parameter(Mandatory=$true)]
  [String]$LocalFile,
  [Parameter(Mandatory=$true)]
  [String]$RemoteFile,
  [Parameter(Mandatory=$false)]
  [System.Boolean]$EnableSSL = $false
)
# Taken from https://www.thomasmaurer.ch/2010/11/powershell-ftp-upload-and-download/
# Create a FTPWebRequest
Write-Host "Creating FTP Object"
$FTPRequest = [System.Net.FtpWebRequest]::Create($RemoteFile)
$FTPRequest = [System.Net.FtpWebRequest]$FTPRequest
$FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$FTPRequest.Credentials = New-Object System.Net.NetworkCredential($Username,$Password)
$FTPRequest.UseBinary = $true
$FTPRequest.KeepAlive = $false
$FTPRequest.EnableSsl = $EnableSSL
# Read the File for Upload
#$FileContent = gc -en byte $LocalFile
Write-Host "Reading File"
$FileContent = [System.IO.File]::ReadAllBytes("$LocalFile")
$FTPRequest.ContentLength = $FileContent.Length
# Get Stream Request by bytes
Write-Host "Sending File"
Add-Content -Path "C:\Powershell\Logs\upload.log" -Value "$(Get-Date) - Submission started of file $LocalFile"
try {
    $Run = $FTPRequest.GetRequestStream()
    $Run.Write($FileContent, 0, $FileContent.Length)
    Write-Host "Sending Complete"
} catch {
    Write-Host "Sending failed"
    Write-Error  $_
    Add-Content -Path "C:\Powershell\Logs\upload.log" -Value "$(Get-Date) - Submission failed of file $LocalFile"
    Add-Content -Path "C:\Powershell\Logs\upload.log" -Value "$(Get-Date) - Error: $_"
    Exit 1
}
#FtpWebResponse response = (FtpWebResponse) request.GetResponse();
#$response = [System.Net.FtpWebResponse]::request.GetResponse()
#Write-Host("Append status: " + $response.StatusDescription);
Add-Content -Path "C:\Powershell\Logs\upload.log" -Value "$(Get-Date) - Submission complete of file $LocalFile"

# Cleanup
$Run.Close()
$Run.Dispose()

After connecting to FTP site how do you do a change directory command, and can you just point to a folder to

deposit the files from local, not having to give them a name just inherent the local file name.

Thanks for reply.. I like the logging

There is a parameter for the destination: $RemoteFile. Again, you should be able to change that simply enough to accept and folder and concatenate the file's name to it in your For-Each loop.

I'm testing with remotefile but have something wrong

$RemoteFile = "ftp://ftp.xxx.com/filedrop/test.txt"

Exception calling "GetRequestStream" with "0" argument(s): "The requested URI is invalid for this FTP command."

At line:18 char:1

+ $Run = $FTPRequest.GetRequestStream()

Thx.

Without knowing more what you're going, or have changed, I can only guess. I know the above works; it is part of an automated process I have that occurs everyday.

I ran script as delivered, and seems like my remotefile something is wrong.

"ftp://ftp.xxx.com/filedrop/test.txt"

If I open a cmd window and feed param in just like script it works.

Thanks.

error:

Exception calling "GetRequestStream" with "0" argument(s): "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)."

Thanks for replies, the script is working there was a security error on ftp site causing issues. The question I have now is how do you

issue a Change Directory command?

When I first hit the site I need to be able to CD to a test or prod directory.

Thanks again..
