UNIX command to copy files from Windows to UNIX box

Hi Folks,

I have a file name abc.xml in my windows machine at the location c:\ytr\abc.xml
which I want to place at the unix box machine inside cde directory.. at the following location that is /opt/app/cde/
now the credentials of unix box are

abc345 -->(dummyid)
ftyiu88--->(dummy passwd)

please advise the unix command to achieve this which I can write when I login to putty, I have tried but it is not working..:confused:

you want to send the file to this directly using ftp, rcp or scp ?

Well with SCP is best , I will log in to putty and then want to execute command..!!

c:\> pscp "c:\ytr\abc.xml" user@linux_host:"/opt/app/cde"

and if you want to scp many files without entering the password everytime setup ssh keys for auto login and copy the file
