In computing, a file shortcut is a handle in a user interface that allows the user to find a file or resource located in a different directory or folder from the place where the shortcut is located.

Shortcuts are typically implemented as a small file containing a target URI or GUID to an object, or the name of a target program file that the shortcut represents. The shortcut might additionally specify parameters to be passed to the target program when it is run. Each shortcut can have its own icon. Shortcuts are very commonly placed on a desktop, in an application launcher panel such as the Microsoft Windows Start menu, or in the main menu of a desktop environment. The functional equivalent in the Macintosh operating system is called an alias, and a symbolic link (or symlink) in UNIX-like systems.

File shortcuts (also known as shell links) were introduced in Windows 95.Microsoft Windows uses .lnk as the filename extension for shortcuts to local files, and .URL for shortcuts to remote files, like web pages. Commonly referred to as "shortcuts" or "link files", both are displayed with a curled arrow overlay icon by default, and no filename extension. (The extension remains hidden in Windows Explorer even when "Hide extensions for known file types" is unchecked in File Type options, because it is controlled by the NeverShowExt option in HKEY_CLASSES_ROOT\lnkfile in the Registry. The IsShortcut option causes the arrow to be displayed.) Shortcut files can be used to launch programs in minimized or maximized window states if the program supports it.
