If your Web site contains files that are located on a different drive than the home directory, or on other computers, you must create virtual directories to include those files in your Web site. To use a directory on another computer, you must specify the directorys Universal Naming Convention (UNC) name and provide a user name and password to use for access permission.
To create a virtual directoryTip If you are using NTFS, you can also create a virtual directory by right-clicking a directory in Windows Explorer, clicking Sharing, and then selecting the Web Sharing property sheet.
To delete a virtual directoryNote In IIS 3.0, any virtual directory not associated with a specific IP address was accessible from all Web sites hosted on the server. In IIS 4.0 and 5.0 this behavior was changed in order to make a virtual directory accessible from multiple Web sites using multiple IP addresses. To make a virtual directory accessible from multiple Web sites that use multiple IP addresses, you must now add the virtual directory to each site.
