Which component allows developers to manage site assets and files in Sitecore?

The Media Library is the correct choice for managing site assets and files in Sitecore. This component functions as a centralized repository where developers and content authors can upload, organize, and manage media items such as images, videos, documents, and other file types used throughout the website. It provides a user-friendly interface that facilitates the classification of files into folders, making them easily accessible for both design and content management.

Being integral to the management of digital assets, the Media Library supports various formats and allows for metadata tagging and searching, which further enhances asset organization and retrieval. It's essential for ensuring that all media is efficiently stored and can be reused in a variety of contexts across different pages.

Other components, while important in their own right, do not serve the same function. The Content Tree is primarily focused on managing the site structure and content items, and Sitecore Experience Manager is the overarching interface for creating and managing the digital experience. Sitecore Analytics, on the other hand, is dedicated to tracking user interactions and gathering insights, not managing files or assets.
