Which panel allows users to manage site files in Dreamweaver?

The Files panel is specifically designed for managing site files in Adobe Dreamweaver. It provides users with an organized view of their site's directory structure, allowing them to easily navigate through files and folders, upload or download files to and from a server, and manage local and remote versions of the site content. This panel is essential for file management tasks, helping users to keep track of all assets they may need while developing their websites.

The Styles panel, on the other hand, is primarily focused on managing CSS styles for the site, allowing users to apply and modify design elements. The Layers panel deals with the arrangement and management of layers on the page and is more relevant for visual layout tasks. The Properties panel provides contextual information and options related to the currently selected object in the document, making it useful for adjusting individual elements rather than overall file management. Hence, the Files panel stands out as the correct choice for site file management.
