CloudShare is a web-based file-sharing system with user authentication, file upload, and secure link generation. Users register or log in, validate credentials against the system, upload single or multiple files to a server folder, and store metadata in MySQL. The system generates unique shareable download links that receivers can use to view file details and download content. This architecture demonstrates a complete end-to-end workflow from user authentication through file delivery, ideal for developers designing secure file-transfer platforms.
