WolfP2P help and troubleshooting

For:All usersNo technical knowledge required.

If WolfP2P shows a More info link, use it first: it opens the explanation for that exact condition. If no link appears, match what you saw to one of the questions below. Some browser restrictions happen inside the browser's own picker and do not produce a WolfP2P error code.

Find help by what happened

I have an error code. Where do I look?

Use the More info link beside the message when one is available. Otherwise, choose the page that matches the words around the code: tunnel and connection errors, file, folder, permission, and disk errors, or transfer and resume errors. Each page keeps the exact codes in its headings so browser search can take you directly to the explanation.

I cannot create a tunnel, join the other person, or keep the browsers connected. What should I check?

Keep both tabs open, confirm that the invitation is current, and avoid repeatedly creating new tunnels while a limit is active. Then use Tunnel and Connection Errors for expired or full tunnels, timeouts, direct-network failures, lost connections, and reconnection problems.

The browser will not let me choose or save a file or folder. What should I do?

Retry the action from WolfP2P and choose an ordinary user-controlled location. If Documents is refused with a system-files message, create a subfolder inside it and select that instead; see protected-folder guidance. Do not weaken browser or operating-system security to make a protected folder available. Start with Browser Folder Permissions; if WolfP2P shows a file, destination, disk, or path error, use File, Folder, Permission, and Disk Errors.

The transfer stopped, failed, or will not resume. Have I lost the completed work?

Not necessarily. Preserve the source and destination, keep both peers online, and follow the retry or resume action shown by WolfP2P. Transfer and Resume Errors explains the exact failure messages, while Transfer Recovery and Reliability explains what Safe mode, Quick mode, completed files, and checkpoints can preserve.

A computer slept, or somebody closed or reloaded a tab. What happens now?

Return to the original tabs first and allow WolfP2P to reconnect when possible. A reload or restored tab is different from genuinely closing it. Follow the dedicated guidance for a computer that slept or a tab that closed or reloaded.

Why can I send individual files but not a folder or choose a destination?

The browser may provide only the partial file-transfer experience. Check Browser and OS Compatibility to see which browsers support folder selection, direct destination writing, nested paths, and disk-backed recovery.

Do both computers need to stay online until the transfer finishes?

Yes. WolfP2P is a live browser-to-browser transfer, not a hosted upload that the receiver can collect later. Keep both computers awake, both tabs available, and the selected source and destination accessible while file bytes are moving.

Before changing files or permissions

Preserve the source and destination until WolfP2P confirms durable completion or identifies what can be reused. Do not delete partial files, bypass a browser warning, or weaken system security merely to make an error disappear.
