How do I transfer my complete address book from Windows live mail to Virgin's mail 2? Tried using export (to a flash drive with csv suffix) and seemed to work. Then when I went to import to Mail 2, it would only allow one address at a time & even this didn't work. Said it wasn't a valid file.
Have bought another computer using Windows 10, so need to have contacts in mail 2, so that the app shows them.
When exporting you choose a folder to export to, is this folder empty of any vCard files (.vcf)?
This video demonstrate concatenation of files, How to Combine Text (.txt) Files; a different command is used to achieve the same result so you may wish to change step (4) to copy *.vcf my_contacts-2017-01-18.vcf
