Nano Transfer File Exchange System

In the modern digital world, sharing data and working together online is a huge part of how students, professionals, and organizations communicate.However, the existing file transfer platforms we use today are seriously lacking.They hit us with restricted file upload sizes, limited storage options, they don't offer real-time chat, and they often force us into expensive, paid cloud services.This paper introduces Nano Transfer -File Exchange System, a new web application designed to solve these exact challenges by bringing hybrid storage and real-time communication together in one platform.The system uses a Hybrid Storage Model that lets you use both local and cloud-based storage options.We built the front-end with ReactJS and the back-end with Fast-API(Python).For security, it uses JWT-based authentication, and for efficiency, it features resumable file uploads and Web-socket-enabled real-time messaging.Nano Transfer allows users to share massive files (up to 5 TB using cloud storage), form groups, and instantly exchange data and messages.This hybrid design makes the system more flexible, cost-effective, and efficient for your daily collaboration and data sharing needs.
