Samsung SYNC SGH-A707

I can't figure out how to transfer files from my PC directly to the microSD card using bluetooth. No matter what configuration I set the phone to the files always are downloaded to the phone memory and not the microSD card. I've tried everything. For example, I turned "bluetooth visibility" on for the card and off for the phone memory. Files still transfer to the phone memory. Sure, I can move the files from the phone memory to the microSD card, as long as they're not too large, but this is a pita.

Any help, ideas, etc.?

TIA
