Import multiple vcard contacts to gmail

To do this first of all you need to concatenate all the VCFs in to a single file...

If you're using windows: 
# open command prompt 
# change to the directory where all your VCFs are stored 
   eg : d: 
   cd my_vcfs 
# Run this command 
   copy   /B   *.vcf   contacts.vcf 

Then just upload the "contacts.vcf" file to google and it will grab all your contacts in one go.

If you're on Linux, OSX, etc., you can use

# change directory

   cd vcf_directory

# concatenate files into a single .vcf

   cat *.vcf > contacts.vcf

Then just upload the "contacts.vcf" file to google and it will grab all your contacts in one go.
