Browser file transfer versus SMB network sharing

For:Advanced users and digital professionals

Assumes familiarity with files, browsers, and common computer workflows.

WolfP2P streams one supervised file set through a temporary browser tunnel without configuring share users, mapped drives, discovery, or a persistent shared folder. It can use a local path when the browsers establish one on the same network, or use the same browser workflow between remote computers. SMB exposes selected files or folders to permitted users, normally across a local or managed network, for repeated access.

WolfP2P uses Cloudflare connection discovery to help browsers connect directly across different networks. Some networks or browser restrictions still prevent a connection. Files travel directly between the browsers, with no TURN relay fallback. See connection discovery and privacy for the network information involved.

Temporary transfer or persistent network share

	WolfP2P	SMB network sharing
Setup	Open compatible browsers and create a temporary tunnel	Configure sharing, discovery, users or permissions, and applicable firewall policy
Persistent exposure	No shared folder remains after the one-file-set tunnel	The share remains available according to its configuration
Primary workflow	One supervised file set	Repeated filesystem access
Typical network scope	Remote or local when a direct path is available	Local or managed network
Users and permissions	Temporary two-participant tunnel	Administrator- or owner-managed share access
Encryption	WebRTC data channel	Depends on SMB version, policy, and deployment
Mapped drives and application access	No	Supported by the operating system and configuration

Which approach fits?

Choose WolfP2P when

Creating share users, mapped drives, or a persistent shared folder would be unnecessary.
The same temporary workflow should work locally or remotely.
The transfer is supervised and one-time.

Choose SMB when

Users or applications need repeated access to the same folder.
Administrators need persistent permissions within a managed network.

Important trade-off

SMB setup can involve selecting users, assigning permissions, enabling network discovery or file sharing, and ensuring firewall policy allows the required traffic. Those controls are valuable for a managed persistent share; weakening them merely to complete a one-time internet transfer is not advisable.

WolfP2P avoids creating a persistent share, but it is interactive, one tunnel carries one set, and both browsers must remain online. It is not a network filesystem and cannot replace SMB for repeated application access.

If you need continuing or managed access, see when configuration is the better choice. For one-time moves, continue with Move Your Folders to a New Computer or the Mac and Windows folder guide.
