How to copy files between unix based system machine and windows machine?

you can use SAMBA to do that samba server to share file from Linux to windows and samba client to connect from Linux to windows share see this link for configuration on Linux (centos ) http://www.centos.org/docs/4/html/rhel-sag-en-4/s1-samba-configuring.html

WinSCP the best

Easiest way is to FTP these files.
There are lots of FTP client software you can use and get from the internet for free but if you know how to use the command line, better :)

The most common and easiest way is "FTP" from unix to windows and vice-versa, by either command line or some ssh tool (provided ftp ports are enabled on the unix/linux machine)

 

Otherwise, there are various other use-cas es that can be met with by different approaches and/or tools. For example WinSCP is one tool for simple grahical file transfers where as Connect:Direct NDM is a enterprise mothod of securely exchanging files between2 systems (not just unix<->windows).

 

Hope this helps !

using samba client

This one can get and send files over SSH1/SSH2, can use pgp/gpg keys and so on.
The another alternative is freeSSHd for Windows, or other SSHD server.
