Conversion of mbk files to vcf file format

We don't know about any .mbk files that could be converted to a contacts list (.vcf) or that have contacts data that could be exported and saved in separate file. You may want to re-check your search query so you are indeed looking for the right file types. Some .mbk files are databases, so perhaps try to import .mbk file to your database program (the one from which your .mbk files are) and export the data to CSV format which can be converted to VCF.
