Set UID - how?

I need to restrict access to a folder on my website. In SmartFTP I set the permissions for users and check Set UID box.
Where do I actually set the User ID? Is it in the SmartFTP, or in some other program.

Hello ..

If you want to change the owner/group of a file/folder you have to do that with the chown command in your telnet/ssh session. If you want to restrict access to certain directories on the HTTP level you should use .htaccess files.
