Hello neetha,
I have not tried what you have said.
But I have a idea.File transferring can only be done using
an FTP protocol.
If your friend has an FTP server.
You can write an FTP client in java/C and then make a connetion to your friends machine and then download the file you want.
I have tried using java programming connecting to reddif.com and retrieved the file contents.
If you want I will give you a sample FTP code in 'C'/JAVA'
Nothing more at present.
bye,
ram.
