Answer 1

You can dig into the Regex library and extract it out using Regex

$test = "Name REGISTRATION_ELI_20221222_071008.csv, Length 0, User ID 1142, Group ID 1220, Accessed 12/21/2022 3:00:47 PM, Modified 12/21/2022 3:00:47 PM"
$matches = [regex]::Match($test,"REGISTRATION.+\.csv")
$Matches.Value

Answer 2

$FilePath | Select-String -Pattern 'Name\s(.*?),' -AllMatches| Foreach-Object {$ .Matches} | Foreach-Object {$ .Groups[1].Value}

Answer 3

Do not parse the name from the string dump of the file object.

The Posh-SSH Get-SFTPChildItem returns SSH.NET SftpFile , which has Name attribute:

$FilePath.Name

(though then the $FilePath is actually a confusing variable name, as it's an object, not a mere path string)

Answer 4

Done, I use substring to $FilePath
