Welcome to LQ!
If you have network connections between the machines: rsync, ftp, scp, a small http server on the source & a browser or wget or curl on the destination...
If you don't have a network connection: usb keys / hard disks, floppies, burning CDs.
As you can see there are many methods. You didn't provide very much information, so it's hard to say what is best for your task.
P.S. Please use more meaningful subjects for your posts. I better one for this post then "Help me" would be "file transfer method"
