What type of server primarily focuses on file storage and access for users?

A file server is designed specifically to store and manage files, enabling users to access and share files over a network. Its primary function is to provide a centralized location for file storage, making it easy for users to save, retrieve, and collaborate on documents. File servers typically handle file permissions and security, ensuring that only authorized users have access to sensitive information.

In contrast, a database server manages structured data and responds to queries from database clients, while a web server hosts websites and serves web content to users over the Internet. A mail server, on the other hand, handles the sending, receiving, and storage of email messages. Each of these servers serves a different purpose, making the file server the correct answer in this context, as it is specifically tailored to file storage and access for users.
