<#The example script looks for log files with the extension *.log inside the Windows folder and all of its subfolders. 
Any log file older than 14 days (defined as not being modified within the past 14 days) is moved to c:\archive. 
This folder is created if it does not yet exist.
You would need Administrator privileges to actually move files out of the Windows folder.#>
