Answer:
Quick Look is a feature of OS X that enables a user to preview the contents of a file without opening the file or starting its associated application. This allows the user to quickly preview a file's contents and determine if it's the file they're looking for without having to go through the process of opening multiple files. Quick Look supports a wide range of file types, including text, images, and videos, and can be accessed by selecting a file and pressing the space bar or by using a touchpad gesture.
