If you have a lot of contacts inside a PST file, doing it manually becomes frustrating very fast. Either it exports contacts one at a time or some details get messed up during conversion. I needed to export a full contact list from a large PST and didn’t want to risk losing numbers or company info. A dedicated PST to vCard converter handled everything together and kept the contact details exactly the same after conversion. WholeClear PST to vCard Converter worked fine for bulk export because it converted the entire address book in one go and the VCF file was ready to import anywhere. Saved a lot of time compared to manual methods.
