If you have several VCF files containing the same contacts, the main challenge is cleaning them together without having to open and edit every file separately. Windows itself does not provide a simple built-in option for comparing duplicate contacts across a group of VCF files.
Start by copying the original VCF files to a separate backup folder. Then load the copies into a VCF duplicate remover that supports batch processing. A practical option is WholeClear vCard Duplicate Remover, which lets you add multiple VCF files at once and remove duplicate contacts while retaining fields such as names, phone numbers, email addresses, addresses, images and URLs. It also works with different vCard versions and does not require Outlook or another third-party application.
Once the cleanup is finished, save the resulting files to a new location and check a few contacts before importing them back into Outlook, a phone or another contact service. Keeping the originals untouched is the safest way to handle a large contact collection.
