The format for pscp is straight forward:


pscp [options] source destination


To copy a Windows file to Linux system, at the DOS prompt, type


pscp c:/music.mp3  ubuntu@10.0.0.3:/home/ubuntu/Music


which will copy the file music.mp3 to my Music folder into Linux.  My Ubuntu EVK has an ip address as 10.0.0.3.  (Note that you can use either / or \ for the Windows files and directories, but you must use / when specifying the Linux files.)


The reverse works as well (copy Linux file to Windows)


            pscp ubuntu@10.0.0.3:/home/ubuntu/Music/music.mp3 c:/


This copies the music.mp3 file from Linux into my C root directory.
