Outlook – Import .eml files in outook 2013

I bought a new laptop a few days ago and installed office 2013, using outlook 2013 as my email client. I have a folder saved on my hard drive that has all my emails in .eml file format. The folder contains all my emails from previous version of windows live mail and now I want this folder to be imported into outlook 2013. Though I like outlook 2013 very much but import function in outlook 2013 is a complicated one. In import function the option to import .eml files does not exists, so is there any other way to import that folder into outlook 2013.
