You can add new directories on the Files page, the Web Files page, the Components tab,
and the Features tab.

Program Files
Represents the Program Files directory on the destination
computer.
Windows
Represents the system directory (regardless of its actual
name) on the destination computer. Some standard
directories are already created under Windows, such as
System32 and Fonts. To create a subdirectory of the system
directory, create it under the Windows directory.
(64-bit installations only.) The Windows directory has an
additional subdirectory, SysWOW64, which stores 32-bit
applications and components.
Program Files (x86)
(64-bit installations only.) A 64-bit system has two
directories for program files: Program Files, in which 64-bit
applications and components are installed; and Program
Files (x86), in which 32-bit applications and components are
installed.
See
32-bit Applications on 64-bit Computers
on page 65.
Global Assembly
Cache
(.NET installation only.) This is used for assemblies that will
be shared by many applications on the destination
computer. It appears only if you select either .NET
Application or Mixed (.NET and Win32) as the
application type on the Product Details page.
wwwroot
Represents the root of the Web server on the destination
computer, which is typically C:\InetPub\wwwroot\

Default directory
If you specify the default directory on the Product Details
page, it appears on the Files page followed by
[INSTALLDIR]. This makes it easy to identify the installation
directory. To enable or disable this option, select Show
InstallDir from the right-click menu.
