It is not clear who you are talking to here but in any case, you want to look at a program such as
WinSCP[
^] which will allow you to copy between systems. Don't get rid of PuTTY - it runs on top of it..
[update] Sorry I see you tagged linux, and the solution above is for Windows machines.
On linux, you want to use scp. Your friend google can help you find out how to run scp on your linux box.
