Data about Internet cookies, including URL names and date/time stamps, is stored where?

The correct option is index.dat, which is a file commonly associated with Internet Explorer and other web browsers. This file serves as a repository for information about cookies, including URLs and date/time stamps. When a browser utilizes cookies to track user sessions or preferences, it stores that relevant information in index.dat.

The index.dat file facilitates the management of cookie data, enabling the browser to quickly reference this information when needed. It plays a significant role in maintaining browsing history and user preferences, reflecting the dynamic nature of web interactions.

In contrast, the other options focus on different aspects of system files or data storage. The INFO2 file is mainly related to the Windows NT file system and is not specifically designed for browser cookies. The EMF file is associated with enhanced metafiles, which are used for storing graphics and images and do not pertain to cookie data. Lastly, pagefile.sys is a system swap file used by Windows for virtual memory management, rather than for tracking browser history or cookies. This distinction clarifies why index.dat is the appropriate answer in this context.
