Share a Folder

You can share one of your folders on the network, enabling other network users to view and optionally edit the files you place in that folder. OS X automatically shares your user account’s Public folder, but you can share other folders. Sharing a folder enables you to work on a file with other people without having to send them a copy of the file. OS X gives you complete control over how people access your shared folder. For example, you can allow users to make changes to the folder, or you can prevent changes.
