A folder on a computer’s operating system where installed software applications store their executable files, libraries, and related data necessary for the program to run. This folder is typically located on the primary drive (e.g., C:\Program Files in Windows) and is organized by subfolders, with each subfolder corresponding to a specific application.
Modern operating systems may include variants such as Program Files (x86) for 32-bit applications on a 64-bit system. The folder is designed to keep software organized and secure, often requiring administrative permissions for modifications.
