A README.md file with informations and examples with description on the differences between the functions would be appreciated.

This is not an issue but a request, first thanks for the amazing script. It's the only one that can really go through subdirectories and get files.

I was wondering if we can add validation to check if the file exists on the remote FTP server to skip it and carry on. I noticed if the script has been terminated and I retry to run it, it starts over and overwrite the existing data so it consume so much time if the script was terminated. Thanks again and hopefully you read my message.

I'm trying to use the get-ftpchilditem from the ftpmodule but is not working.

Below the commented lines in the file to use as an example.
Both of them seem to have the option -ftpfilepath wrong since the function is expecting $ftpfolderpath.

#Get-FtpChildItem -ftpFilePath "ftp://myHost.com/root/leaf/" -userName "User" -password "pw" -hidden $false -File
#Get-FtpChildItem -ftpFilePath "ftp://myHost.com/root/leaf/" -userName "User" -password "pw" -Directory
function Get-FtpChildItem($ftpFolderPath, $username, $password, [System.Management.Automation.SwitchParameter]$file, [System.Management.Automation.SwitchParameter]$directory, $hidden = $true) {

If I run
Get-FtpChildItem -ftpFilePath "ftp://192.168.1.1/DIR/" -userName "User" -password "pw" -hidden $false -File
I get the follwoing error

Exception calling "Create" with "1" argument(s): "Value cannot be null.

Your Example isn´t correct:

#Get-FtpChildItemHidden -ftpFilePath "ftp://myHost.com/root/leaf/" -userName "User" -password "pw" -File -Directory

should be:

#Get-FtpChildItemHidden -ftpFolderPath "ftp://myHost.com/root/leaf/" -userName "User" -password "pw" -File -Directory
