Yes, just put the card in the phone and connect to the computer via the cable. Then go to your my computer and you should see an icon for mobile device and then in the directories browse around until you find the storage card directory.

There it is. Also to save some memory, make sure and install most applications to the storage card instead of the main memory. When you install, the phone will ask you where to install to.

For me, I have about half a gig of music and work document on the card and the other half of the storage card is basically blank, but I use it to transfer files from one computer to another all the time.

Hope that helps
