Merge all of your vCards into one .vcf file via the command prompt in Windows and then just import that file to Gmail, Hotmail or ICloud.
- Open Command Prompt
- Now type cd C:\MyContacts and hit Enter. This will make sure the directory is pointing to the root of the C :\Drive
- Now type copy /B *.vcf all_in_one.vcf and hit Enter.
- This will immediately start to merge the multiple .vcf files into one file called all_in_one.vcf
- Open your mail from the browser and under contact just select the import options
