Does this work offline?
Yes! Once you've visited the app online, it's cached for offline use. Resources are cached as you view them. P2P sharing works without internet.
What file types are supported?

Is P2P sharing secure?
P2P connections are established directly between devices using WebRTC. No data passes through our servers. Executable files are blocked for security.
Connection failed - what to do?
Ensure both devices are on the same network or have internet access for the initial handshake. Check firewall settings and try again.
