How to count files in FTP directory
Solution 1:
The $list contains:
file1`nfile2`nfile3`n
If you split the string by "`n", you (correctly) get four parts, with the last one being empty.
You can use an overload of String.Split that takes StringSplitOptions and use RemoveEmptyEntries:
$list.Split("`n", [System.StringSplitOptions]::RemoveEmptyEntries)
