how to import Windows Live exported messages that are ".fol" files ?

I exported my Windows Live messages to external drive as backup.  Each message is a “.fol” file.  Can I import these into em Mail?  I don’t see this as an option on Import menu.  Unfortunately my laptop hard drive crashed and I no longer have Windows Live client program to attempt to re-export email messages in a different format.  Alternatively, can I get Windows Essentials download somewhere (with Windows Live) to attempt to transition to em Mail?  Microsoft doesn’t support Essentials as download anymore.
