Esse script é uma modificação de um script do simple-talk apenas adicionar a opção de função para facilitar a vida

o importante para este script funcionar é:

1. criar um diretório com o nome Script-DBObjectsIntoFolders dentro do diretório C:\Windows\System32\WindowsPowerShell\v1.0\Modules\
2. Salvar este script com o nome Script-DBObjectsIntoFolders.psm1
3. Usando o powershell digitar import-module Script-DBObjectsIntoFolders

#https://www.simple-talk.com/sql/database-administration/automated-script-generation-with-powershell-and-smo/

function global:Script-DBObjectsIntoFolders([string]$server, [string]$dbname, [string]$DirectoryToSave){
