Two different versions of the Program Files folder and the Windows System folder
A 64-bit Windows has two different versions of the program files folder and the Windows system folder (system directory). One version is intended for 32-bit files and other version is intended for 64-bit files. The name of these folders, and the bit they are intended for, is shown in the table below:| Folder name | Bit | Description |
| System32 | 64 | Windows System folder (system directory) for 64-bit files |
| SysWOW64 | 32 | Windows System folder (system directory) for 32-bit files |
| Program Files | 64 | Folder for 64-bit program files |
| Program Files (x86) | 32 | Folder for 32-bit program files |
Below you can see the full path to the folders.
| Folder name | Folder path | Description |
| System32 | C:\Windows\System32 %windir%\System32 |
Windows System folder (system directory) for 64-bit files |
| SysWOW64 | C:\Windows\SysWOW64 %windir%\SysWOW64 |
Windows System folder (system directory) for 32-bit files |
| Program Files | C:\Program Files | Folder for 64-bit program files |
| Program Files (x86) | C:\Program Files (x86) | Folder for 32-bit program files |
| C:\Windows\Sysnative |
the following folder path is actually used:
| C:\Windows\System32 |
To provide support for allowing existing 32-bit applications to work on 64-bit versions of Windows, most 64-bit versions of Windows use 32-bit Windows-on-Windows (WOW64) emulation. This WOW64 emulation support isolates the 32-bit and 64-bit files from each other by storing their files in separate locations.
A 64-bit target system typically has two Program Files folders:
- Program Files, which is for 64-bit applications
- Program Files (x86), which is for 32-bit applications
A 64-bit target system typically has two Common Files folders (one in either Program Files folder):
- Program Files\Common Files, which is for 64-bit applications
- Program Files (x86)\Common Files, which is for 32-bit applications
A 64-bit target system also typically has two system folders:
- System32, which is for 64-bit libraries and executable files
- SysWOW64, which is for 32-bit libraries and executable files
