I recently exported my contacts from an old phone and ended up with a single VCF file containing over 1000 contacts. Now, I want to split this large vCard file into individual VCF files for each contact (or at least smaller manageable batches). Is there a free or reliable method to do this without losing any data or formatting? I am looking for a safe way—manual or using a trusted tool—that can handle this kind of bulk vCard split.
