## Overview

This is a Hono/Sequelize backend for a file-management product. The main user workflow enters through HTTP routes, passes authentication and validation, then reaches controllers that handle identity, file/folder operations, or uploads; repositories and services provide persistence and supporting behavior. The tree and excerpts also show token/session management, sharing, notifications, API tokens, scheduled work, and socket support. Several subsystems are represented by their exact directories because their source was not sampled; their internal call paths are therefore omitted or marked unverified.

Main entry points: [`src/middleware/auth.middleware.ts`](https://github.com/venu123143/fileflowbe/blob/main/src/middleware/auth.middleware.ts) (Auth Middleware), [`src/config/database.ts`](https://github.com/venu123143/fileflowbe/blob/main/src/config/database.ts) (Sequelize Database), [`src/server.ts`](https://github.com/venu123143/fileflowbe/blob/main/src/server.ts) (HTTP Server), [`src/global/routes.ts`](https://github.com/venu123143/fileflowbe/blob/main/src/global/routes.ts) (Route Registry)
