How Can I Remove Duplicate Contacts from Multiple vCard (VCF) Files at Once?

I have several VCF files exported from different devices, and many contacts are repeated across them. Manually checking each file is not possible. I need a simple way to remove duplicates in bulk and keep only unique contacts.

 

When you have multiple VCF files coming from different devices, duplicates usually show up because each export saves the same contacts again instead of syncing them. So you end up with repeated names, emails or numbers spread across files.

In case of smaller data, a manual solution can be found by opening the VCF files in a text editor or importing them into a contacts management application like Outlook or Google Contacts and merging the duplicates there. It works fine, but when the number of files grows, things get messy and tedious and there is always a risk of overlooking some duplicate records.

When dealing with larger number of files, I came across Softaken vCard Duplicate Remover being used for that purpose. It supports importing several VCF files simultaneously and can filter out duplicates in data such as names and telephone numbers, thereby exporting the file without duplicates. One must be cautious about always having backups while merging anything.
