convert emails from .eml and contacts from .contact files from a system backup drive

I need to convert emails from .eml and contacts from .contact files from a system backup drive. My previous PC was stolen so all I have are the files. How do I get these much needed files into eM Client?  Also, on the import window in eM Client does not have an option for .contact files.  These were created in Windows Mail so you’d think they would be included.

eml files you can import directly into eM Client using Menu > File > Import > Email (eml). 

Contacts can only be imported from csv or vcf files.

eM Client does not import from Windows Mail.
