in OX Lion the default FTP Server is hidden but it still exists. You just have to enable it. Use following command
sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist
I had to transfer a big (4GB) file over to windows system and i found this was the only QUICKEST way of doing it.
You can use any ftp client at windows system and connect to the ftp server from mac.
Host = IP Address of your mac (use ifconfig from termial)
User = Your Mac User name
Password = Your Mac Password
And Connect
It will list all mac user’s directories and you can transfer whatever you want…
Enjoy,
