Some time ago, I was trying to convert my VCF contact file to Lotus Notes NSF format, for which I tried using the manual process, which proved to be quite complicated. However, I found out about WholeClear VCF to NSF Converter through the Internet; then I also tried it, which is easy to use and reliable. Moreover, it can easily save your VCF file to NSF format and is supported with all vCard versions: 2.1, 3.0, 4.0, etc., and can also transfer VCF files from any email application including Skype, Google Contacts, iCloud, and Outlook to any version of Lotus Notes. It can be easily downloaded in all versions of Windows OS: 11.0, 10.0, 8.0, 7.0, Vista, XP, etc. You can try the demo version, which is available free to all users and can transfer up to 25 vCard (.vcf) files in NSF format.
