Title: How to Enable or Disable Simple File Sharing in Windows XP

Objective: The objective of this demo is to teach you how to enable or disable simple file sharing in Windows XP. If you turn off Simple File Sharing, you have more control over the permissions to individual users. However, you must have advanced knowledge of NTFS and share permissions to help keep your folders and files more secure. If you turn off Simple File Sharing, the Shared Documents feature is not turned off. Simple File Sharing is always turned on in Windows XP Home Edition-based computers. By default, the Simple File Sharing UI is turned on in Windows XP Professional-based computers that are joined to a workgroup. Windows XP Professional-based computers that are joined to a domain use only the classic file sharing and security interface.
