Can any one guide me through the process of sending a file from a pc to more than one mobile using bluetooth at a time(it may not be a parallel process)... is it possible?.. im doing a project over a secure data transfer using bluetooth.

C:\project\...\runmenu>runmenu /wait:window /exec:"Send To\Bluetooth device" c:\lines.txt

i used this code to send a file but it sends for only one mobile which is paired.. runmenu made for calling Explorer's context and Send to menu items from .BAT files.
