It is seen that Windowsx64 Edition Operating System has following two directories:-
1. Program Files
2. Program Files(x86)
Windows XP Professional x64 Edition redirects the \Program Files directory for all programs that are 32-bit during the installation to the \Program Files(x86) directory. Programs that are 64-bit compatible are installed into the \Program Files directory.
The \Windows\SysWOW64 directory is where 32-bit system files are installed. 64-bit system files are in the \Windows\system32 directory for compatibility reasons.
