importing contacts

Help? Will someone please tell me how to import contacts from either my iTunes, or from the contacts folder on my PC. I have tried creating a VCF file from iTunes, as well as from an iPhone app called contact backup & transfer, but EM client will not recognise the VCF file. If I select the (not listed) specific file, by typing it’s name in the box, it says “the folder name is not valid” I hope someone can help!
