FTP Node: File Transfer Client

FTP Node is a high-performance, production-ready dual-role application that turns your Android device into a wireless FTP Server while providing an advanced Remote FTP Client. Built with modern Kotlin Coroutines, Jetpack Compose Material 3, and Scoped Storage compliance, FTP Node makes file transfers between your phone, PC, Mac, and remote servers instant, secure, and cable-free.

No USB cables, no slow Bluetooth pairing, no file size caps, and no cloud relays. Enjoy direct peer-to-peer speeds across your local Wi-Fi or portable hotspot!

🌟 DUAL-MODE FUNCTIONALITY:

📡 1. BUILT-IN EMBEDDED FTP SERVER (HOST NODE)

• Wi-Fi & Hotspot Ready: Share files anywhere—even outdoors or on flights—by broadcasting your phone’s hotspot without internet.
