- Description
- The Microsoft Internet Shortcut format (URL file format) is built upon a plain text file and adopts an "INI" or configuration file style 'section + key-pair' format, to provide machine-readable structure to describe a method of accessing a web page or website. The format enables the encapsulation of the information needed to connect to a website in a file-based object, which can be distributed or saved elsewhere on the user's hard-disk, for example, in enabling bookmarking of web-sites as a user's favorites. The Microsoft Internet Shortcut format included features such as hotkey instructions, allowing users to make use of a combination of keys on a keyboard to launch a website. The association of the '*.url' file-format extension with a web-browser application enabled double-clicking of the file object to launch a website.
