How to merge hundreds of VCF files into one without data loss?

If you want to merge hundreds of VCF files safely, go for a dedicated VCF merger tool instead of trying manual methods. WholeClear Merge vCard Software is one of the most reliable options I’ve used. It combines unlimited .vcf files into a single contact file without losing names, phone numbers, emails, photos, or any custom fields. It supports all vCard versions and platforms, so formatting stays intact. You just load your folder, preview the contacts, and export them as one unified VCF file. The free version even lets you test by merging 25 files first, so you can check accuracy before upgrading.
