On Microsoft Windows, a special folder is a folder which is presented to the user through an interface as an abstract concept, instead of an absolute folder path. This makes it possible for an application to ask the operating system where an appropriate location for certain kinds of files can be found, regardless of what version or language of operating system is being used.

Windows uses the concept of special folders to present the contents of the storage devices connected to the computer in a fairly consistent way that frees the user from having to deal with absolute file paths, which can (and often do) change between operating system versions, and even individual installations. The idea has evolved over time, with new special folders being added in every version of Windows since their introduction in Windows 95.

Microsoft's "Compatible with Windows" software logo requires that an application make use of special folders locations to locate the appropriate folders in which documents and application settings should be stored.
