Conversion of bak files to vcf file format

Some mobile devices in the past used .bak files for backups of their contacts. There is no clear answer whenever a bak to vcf conversion is possible, as some .bak files may be simply renamed contacts files (.csv, .vcf) and others can be renamed special vendor specific formats that can only be handled by the original software.

Your best solution for attempts to convert bak to vcf  would be most likely to contact the support of your phone device or check user forums for more information. Of course you can always try to rename bak to vcf and hope for the best.
