### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
    $watcher = New-Object System.IO.FileSystemWatcher
    $watcher.Path = "D:\INTERFACE"

### DEFINE ACTIONS AFTER A EVENT IS DETECTED

    }    
### DECIDE WHICH EVENTS SHOULD BE WATCHED + SET CHECK FREQUENCY  
    $created = Register-ObjectEvent $watcher "Created" -Action $action
