Transfer file while in cradle to PC folder share

I am looking to write an android app/service that when the TC51 is placed in its cradle it will transfer files from the sd card to a folder share on the PC the cradle is connected to.

It seems the only solutions I can find are have the PC expose a web service or install 3rd party CIFS software.

Seems there should be an easier way or is this not a common functionality of this device?  Any input would be appreciated.
