Share a folder in Windows Vista.

1.	Ensure that file sharing is enabled as described in the “Enabling File and Printer Sharing Options” section of this article.
2.	Click Start, and then click Computer.
3.	In the Computer window, navigate to the folder containing the folder that you want to share.
4.	Right-click the folder that you want to share, and then click Share. The File Sharing window is displayed.
5.	If you have password protected sharing enabled, use the File Sharing window to select which users can access the shared folder and their permission level. To allow all users, select Everyone in the list of users. By default, the permission level for a selected user is Reader. Users cannot change files or create new files in the share. To allow a user to change files or folders or create new files or folders, select Co-owner as the permission level. Figure 5 shows an example of configuring users and permission levels in the File Sharing window. If you have password protected sharing disabled, use the File Sharing window to select the Guest or Everyone account. This is equivalent to simple file sharing in Windows XP.
6.	When complete, click Share, and then click Done.
