Conversion of nbf files to vcf file format

It is unlikely that you can directly convert NBF backups from older Nokia phones to VCF files (contacts). However, you might be searching for a way to extract the contacts from NFB backups (NBF = / = NFB), something that is certainly doable. For this you will need Nokia NbuExplorter or similar utility and just extract the contacts, which are saved in a CSV file. To get the the vCard file (.vcf) you just have to use one of the existing csv to vcf conversion options.
