What is the function of the cookies folder in a web browser?

The cookies folder in a web browser is primarily used to save login credentials and session tokens. When a user logs into a website, cookies help the browser remember that session, so the user does not have to log in again every time they navigate to a different page on that site. This is achieved by storing small pieces of data, known as cookies, which can include user preferences, session information, and authentication details.

Moreover, cookies play a critical role in enhancing user experience by maintaining stateful information across different browsing sessions. For instance, if a user adds items to a shopping cart, cookies can remember those items even if the user leaves the site and returns later.

The other options either focus on different functionalities of a web browser or reference folders that serve other purposes. For instance, the history feature tracks all the web pages visited by the user, bookmarks allow users to save and retrieve specific websites easily, and temporary files are used for caching content during web page loading for speed optimization. However, none of these accurately describes the primary function of the cookies folder.
