The "Recently Used" feature is a function found in many software applications and operating systems. It displays a list of files, documents, or applications that a user has accessed recently. This feature helps users quickly locate and reopen items without having to search through folders or menus. Typically, the "Recently Used" list is found in the main menu or toolbar of an application, such as Microsoft Word or Adobe Photoshop. It enhances user efficiency by providing easy access to frequently used items, streamlining workflows, and saving time during tasks.
