This is a simple file management application that allows users to upload and download temporary files from any terminal using curl or wget. The backend is built using FastAPI with SQLAlchemy for database management, and the frontend is built using Streamlit. The application supports user authentication and each user has their own directory on the server.

• User registration and authentication
• File upload and download
• File space checking for each user
• Streamlit frontend for user interaction
• Backend API with FastAPI
• SQLite database with SQLAlchemy
• Dockerized using Docker Compose
