Can I use the USB-C cable for my charger to transfer large files between different OS X laptops? I have more than one Mac Book Pro, and need to transfer large files between them.

Can I repurpose the USBC cable for power to transfer between Mac Books? 

Is there a better/faster cable, or way to transfer files between MacBooks?
The charger included with the 2016 MacBook Pro is a standard USB Type C cable. It should achieve speeds of up to 10gbps. 
If you'd like speeds of up to 40gbps, I'd buy an official thunderbolt 3 cable from Apple. These should have the highest speeds. 

NOTE: My bad, I looked into it and the cable is a standard USB C cable, not thunderbolt. Answer has been changed to reflect that.
