FTP transfer script with user prompt for remote destination

I have a script I wrote to transfer files from a Windows 10 tablet to a remote for server working as intended. New wrinkle is that the user wants the ability to either select an existing directory on the remote server or enter the name of a new directory to be created. I’m really stuck. Can anyone point me in the right direction? My Google foo is failing me.

Thanks!

Are you sure you’re using ftp and not smb/cifs? What is your current script?

Yep, positive it’s FTP:

#Specify the directory where all files that we want to upload
$source="C:\Users$Env:username\Pictures\Camera Roll"
$destination = “ftp://phototransfer@10.24.0.90//media/data/photos/

$webclient = New-Object System.Net.WebClient

$files = Get-ChildItem $source

foreach ($file in $files)
{
Write-Host “Uploading $file…”
$webclient.UploadFile(“$destination/$file”, $file.FullName)
Remove-Item $source/$file
}

$webclient.Dispose()
