The Preferences folder exists to store an application's settings. Preferences files, often shortened to "Prefs files", are often stored inside the folder.

Classic Mac OS[]

All preferences are often stored in a unified, centralized Preferences folder in the System Folder of classic Mac OS. Additional folders may be created inside the folder itself.

Mac OS X and macOS[]

With Mac OS X (now macOS), the situation got a whole lot more complicated. Generally, system-wide settings that apply for more than the current, logged-in folder are stored inside the Preferences folder inside the Library folder on the root level of the Mac OS X startup volume. Settings for applications on a user-per-user level are stored inside the Preferences folder located inside the Library folder in the user's Home folder.
