You can download winscp and just connect to server and copy that file to your XP

Download winscp from below site

If i want do as sharing folder with unix and windows XP . how to perform. my IP address is 192.168.2.222 for XP and Unix is 221

Then you have to start a file sharing service on the unix system. Either nfs or samba (smb).
Which version of unix/linux are you using?

If still relevant: also ftp can be used. On windows install Filezilla and on Unix setup ftp if it is not configured yet.
