📶

LAN discovery

Nearby FileFly devices announce themselves on your Wi‑Fi so you can tap and send — cross‑device file transfer without hunting IPs.

Streaming transfers

Large payloads stream with live speed, ETA, and shared progress on both phones — built for the fastest file transfer feel on LAN.

📦

Apps with splits

Send installed apps including split APKs, then install them together on the receiver — a practical USB alternative for app sharing.

📁

Folders & docs

Share whole folder trees and documents — not just media. True wireless data transfer for everyday files.

Trust & control

Bank-Level Security & Control

🏦

Bank-level E2E option

ChaCha20‑Poly1305 encryption when you want public‑Wi‑Fi peace of mind — bank‑grade stream protection without cloud servers.

🔑

PIN confirm

A 4‑digit PIN on the sender must be entered by the receiver before transfer starts — fewer surprise transfers.

🔔

Background continuity

Foreground service + notification keep transfers alive when the screen sleeps — reliable offline file transfer on your LAN.

🖼

Gallery + FileFly folder

Media can appear in Photos while everything also saves into FileFly — clear destinations after wireless file sharing.

Connect any way

Cross-Platform File Sharing Options

Phone‑to‑phone, QR Quick Connect, and desktop workflows — transfer files between devices on the same WiFi network.

Quick Connect QR

Show your code or scan a friend’s — skip hunting through long device lists when discovery is noisy.

📱

Android first

Native path for permissions, storage, install packages, and battery exclusions — built for fast Android nearby WiFi sharing.

💻

Desktop to mobile WiFi file sharing

Open Computer Hub in a browser on your PC and pull or push files over the local link — no cables required.

🗄

FTP mode

Classic FTP for tools and workflows that already speak the protocol — network file sharing on your terms.

Security

Optional bank‑grade encryption on every transfer

Leave E2E off on trusted home Wi‑Fi for max speed. Turn it on for cafés and guest networks. PIN confirm stays available either way. See bank‑level security details.
