Who covers the relay?
We always try a direct connection first, and a direct one wasn't possible between these two networks this time. A relay is a secure server that passes your files between the two devices when your network blocks a direct connection. Running it uses paid bandwidth, so relay transfers need someone to cover them — direct device-to-device transfers are always free. Choose who covers this one.
Why did this happen?
Direct connections between two Wi-Fi networks usually work. Mobile data often blocks them, because carriers share one network address between many phones, and many use a newer address type that home networks often cannot reach directly. We looked for a direct path and none was possible between these two networks this time. A relay passes the encrypted transfer through a server, and that bandwidth costs money, so someone covers it.

Not enough relay quota
Your account doesn't have enough relay quota left for this transfer. Try again, choose a different payer, or cancel.

Direct file transfer, device to device
FileTransferX is the direct way to move files between two devices. Pick Send Files on the device that has what you want to share, and Receive Files on the other, then pair them with a QR code or a short transfer code. No email attachment, no cloud upload — direct peer-to-peer transfers need no account at all.
This is real device-to-device file transfer, not a file transfer online service that stores a copy on someone else's server while a recipient waits to download it. Once your devices are paired, files move directly between them. If your network blocks a direct connection, FileTransferX falls back to a secure relay — the relay uses paid bandwidth, so one person covers it with a free account and its one-time relay allowance. That is what makes large file transfer practical here: video files, RAW photo exports, and full folders move without hitting the size limits that email and many upload-based tools enforce.
The same Send and Receive flow works for every combination of devices. Use it for mobile to PC file transfer when you want your phone's photos on a laptop, for PC to PC file transfer between two computers on different networks, or for Android to iPhone file transfer, where AirDrop and Nearby Share don't apply. Nothing you send is stored after the transfer finishes, and closing the tab clears the session, so pick Send or Receive above whenever you're ready to start.
