The Network and Sharing Center applet in Control Panel provides the following links for monitoring shared folders:

• Show me all the files and folders I am sharing
• Show me all the shared network folders on this computer

The Shared Folders System Tool has three nodes for monitoring and managing shared folders:

• Shares: This node allows you to create new shares, configure existing shared folders, and optionally stop sharing them.
• Sessions: This node allows you to see which users are connected to this computer.
• Open Files: This node allows you to see which files and folders are opened through file shares on this computer.
