On 64bit versions of operating systems Windows creates 2 folders: Program Files and Program Files (x86). The explanation is pretty simple:
- Program Files - contains applications that are created for 64bit versions of Windows. In this folder are placed all the 64bit compatible applications.
- Program Files (x86) - contains applications created for 32bit versions of Windows that run on 64bit versions as well.
Warning: Do not attempt to manually delete folders inside Program Files unless you're instructed to do so by an It technician.
