Save WSP from Sharepoint Central Admin

I was searching for the solution to download the WSP from Sharepoint Central Admin and i got a Poweshell script which saves the WSP on physical device from Sharepint CA.


$sharepointFarm = Get-SPFarm
$wspFile = $sharepointFarm .Solutions.Item("<WSP Name>").SolutionFile
$wspFile .SaveAs("<Your Physical Path>\<WSP Name>")
