I want to transfer files between two laptops without network cable using bluetooth. Is it possible? Any softwares needed?

Yes its possible.
But note that bluetooth device has its range,amount of data its can transfer at a time,speed
If data being transferred is large, man this can take a very long time.

All u have to do is configure the bluetooth on each laptop to see each other.

scan 1 bluetooth to detect the other.
enter the password.
and u done,happy transferring...

hope this helps...
