Program files may refer to any of the following:

1. When used as a singular noun, an application file or program file is a description of a file that stores the code to run a program. This type of file is commonly referred to as an executable file. When referring to more than one file, program files are all of the different files that allow a software program to run on your computer. Most programs have different types of files (e.g., DLL files, data files, etc.) that are used in conjunction with the executable file.

What programs should be in the Program Files folder?

The Program Files folder and Program Files (x86) folders should contain the folders of the software programs that have been installed on the computer.

Can I delete Program Files or Program Files (x86)?

No. While it may be possible to delete these folders they are both part of Windows and default locations where Windows installs your program files. If you delete either of these folders, the programs that have been installed on your computer that are contained in this folder will also be deleted.


If you want to delete these folders to recover hard drive space, we suggest uninstalling programs and not deleting these folders.

What is the progra~1 directory?

With early versions of MS-DOS and Windows that only supported the 8.3 file naming format, the "Program Files" directory was too long. For backward compatibility, the "Programs Files" directory would appear as "progra~1" (a maximum of eight characters). Today, because all operating systems support long files this directory name is rarely seen.
