How to Merge Multiple vCard Files Before Importing into Google Contacts?

[Jenson01]

I recently exported contacts from different devices and applications, and now I have multiple VCF (vCard) files. When I try to import them into Google Contacts, it only allows me to upload one file at a time. Importing each file separately would be very time-consuming since I have hundreds of them. Can anyone suggest an easy way to merge multiple vCard files into a single VCF file before importing into Google Contacts? I am looking for either a manual method or a reliable tool that can do this without losing any contact details.
