Import multiple contacts from a vCard file (vcf-file)

I’ve got a vCard containing my contacts which I created by exporting my contacts from another application (Lotus Notes). However, Outlook seems to only support importing the first contacts from that file.

I then split this multi-contact vCard file into separate vcf-files, one for each contact, which all reside in a single folder. However, Outlook seems to only support importing 1 vCard at a time.

Is there any way I can import all these vcf-files at once or import this single multi-contact vCard in Outlook?
