Virtual folders reference currently existing folders on your computer's hard drive. A virtual folder name is only an alias for the real folder. When you create a virtual folder, you do not have to give it the same name as the folder it references.
In the Administrator, connect to the server, then click the VFS tab.
In the left pane, click the folder in which you want to add a virtual subfolder, then do one of the following:
Right-click the folder, then click New Virtual Folder.
On the toolbar, click the New Virtual Folder icon.
On the main menu, click Configuration, then click New Virtual Folder.
The New Virtual Folder dialog box appears.
In the Alias box, type a name for the folder.
In the Target
box, specify the target folder by typing the path or click the folder
icon and
browse to the target folder.
Click OK. The new virtual folder appears in the tree with the name that you typed in the Alias box, plus "Virtual" and the full path.
