Adding filenames to an array? - powershell

Question

I'm trying to add filenames of certain txt files on a watched folder to an array for further analysis. The code is as following
$Array = New-Object System.Collections.ArrayList
$onCreated = Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$path = $Event.SourceEventArgs.FullPath
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
Write-Host "The file '$name' at '$path'was $changeType at $timeStamp" -fore white
$file=Get-Item $root\UNB\TMP\FACT_TEMPORAL.TXT | Rename-Item -NewName {("print-"+'{0:yyyy-MM-dd-hh_mm_ss}{1}' -f (Get-Date),".txt")} –PassThru
$archivo=$file.Name
Remove-Item $root\UNB\TMP\FACT_TEMPORAL.txt
comprobar_archivo($archivo)
}
The function to add it to the array is:
function comprobar_archivo($archivo) {
Write-Host "COMPROBANDO ARCHIVO $archivo" -fore white
$Array.Add($archivo)
write-host "CONTENIDO INICIAL ARRAY $Array"
foreach ($element in $Array) {
limpia($element)
leeyedita($element)
printpdf($element)
borrar($element)
borrar_array($element)
}
}
Seems that the write-host "CONTENIDO INICIAL ARRAY $Array" is not showing anything, further more the script gets frozen, it wont execute anymore. I don't know what I'm doing wrong, or how should I pass the filenames correctly in order to work.
How do I delete a specific name from the array? I was using:
$Array.Remove([String[]]$archivo)
But it wont work...
