In order to work with a Unix remote server from my Windows machine, I had to use Putty in place of ssh. However, I had to move a file from this remote server to my client Windows machine, and Putty is not a parallel of scp (which I normally use on my Mac).
However, pscp seems to be that parallel. I downloaded it from the same place as Putty: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Here was the command to download:
username@remote-host:remote-file-to-download-name local-name-for-this-file
You can find a number of examples for using this at http://e-articles.info/e/a/title/Transfer-files-from-the-command-line-with-PSCP/
