Unblock multiple files with PowerShell

Because I always forget to unblock files before I extract the zip files from Microsoft: Here is a PowerShell command to do it after the zip is extracted and a whole bunch of files are blocked

dir -Path .\FinanceAndOperations_10.0.136.10007_Application\ -Recurse | Unblock-File

this is definitely faster then deleting all the files and extracting again.
