Transferring File through Infrared

Hi friends

I am developing an application which is transferring file from mobile to Laptop via Infrared. Already this facility is there in mobile. But I want to integrate this with our application. I am following SDK document which is transferring buffer via infrared.
Now my application is discovering the PC within range. But I am not able to transfer the buffer data to pc.
In my case instead of buffer I want to transfer file. I donÂ’t have any idea about it.

If you know any link or example, plz send it to me. Otherwise guide me how to do this.  

Thanks in advance
