Browser file transfer versus a USB or external drive

For:All usersNo technical knowledge required.

WolfP2P streams selected files directly to the receiver's destination without first copying them onto removable storage. It requires no physical handoff, creates no transfer device that must later be returned or erased, and can recover verified progress on compatible browsers. A USB drive, external SSD, or external hard drive works offline but must be physically connected to each computer in turn.

The current connection configuration uses host candidates only, with no STUN traversal between separate private networks and no TURN relay. A shared or otherwise directly reachable network can work, subject to browser and network policy; remote reachability is not guaranteed.

Which approach fits?

Choose WolfP2P when

  • You want to avoid carrying, lending, and securely erasing removable media.
  • Verified recovery during a long live transfer matters.
  • The computers can remain online together.

Choose physical media when

  • The computers cannot be online together.
  • The destination is isolated or an offline physical handoff is required.

Important trade-off

USB introduces a deliberate middle copy: source computer → removable drive → destination computer. That is useful when the machines are not simultaneously available, but it needs enough drive capacity, compatible ports and filesystems, and physical access to both machines.

WolfP2P avoids that middle device, but both computers must remain online and able to establish a direct connection. For migration decisions, see Transfer Files to a New Computer.
