Basically, you have to buy a bluetooth adapter for your computer in order to be able to connect with the Razr.

Basically looks something like that. It looks like a flash drive with the Bluetooth logo on it.
When you plug that into one of the USB ports, follow the instructions and your computer will then be able to connect with your Razr.
If you don't want to do that, then you could always buy a USB cable compatible with your Razr and transfer files that way.
