What are the common issues when users try to merge vCard files manually?

I’ve seen people trying to merge vCard files using text editors or free scripts. What are the problems with these methods, and why should users choose a professional VCF Merger Tool instead?

When users try to merge vCard files manually, they often run into a few common issues. First, handling thousands of small VCF files is time-consuming because you need to open and copy contacts one by one. Second, manual merging can easily lead to data loss or formatting issues , especially with contact fields like phone numbers , emails or images. Third, duplicates become a big problem because there is no built-in way to detect and remove them. Lastly, different vCard versions (2.1, 3.0, 4.0) may not merge properly by hand , which causes compatibility errors. That is why many people prefer a dedicated VCF Merger Tool like WholeClear Merge vCard Software to save time and keep contacts safe.
