I am trying to back up the Windows Live Mail client program folders - inbox, sent, drafts.  I have done this before, but cannot locate where these files are stored on my hard drive.  I tried going to "c: //users/(myname)/local/applications/microsoft/windows live mail" but was unable to find the email folders.  

Note - I am not trying to import these notes into another program.  I only want to back them up to an external hard drive.

Does anyone know how I can do this?  I am using Windows 8.1 and Windows Live Mail 2011 client program.
