Click the switch to turn it on. Once enabled, the page will display your local device ID and the local file list, and you will be able to connect to remote devices.
Notes
-
If the switch cannot be turned on, please check your network connection and login status first.
-
Do not disable the P2P feature during transfers, as this may interrupt the connection.
4. View, Refresh, and Copy Device ID

Prerequisites
The P2P feature has been enabled.
Steps
-
Locate "My Device ID" at the top of the page.
-
Click "Copy" to copy the device ID to your clipboard. Share it with your partner.
-
To regenerate a new device ID, click "Update".
Notes
-
After refreshing the device ID, the old ID may no longer work. Please notify the other party of the new ID promptly.
-
Do not expose your device ID to unauthorized personnel to prevent connection requests from unknown devices.
5. P2P Permission Configuration

Prerequisites
-
The P2P feature has been enabled. When enabled, the permissions [Allow receive files from others] and [Allow others to view file list] are turned on by default. You can adjust these based on your actual usage needs.
Permission Descriptions
| Setting | Description | Recommendation |
|---|---|---|
| Allow receive files from others | Allows other devices to send files to this device. | Enable when you need to receive files. Enabled by default when P2P is turned on. Disable when not receiving external files. |
| Save path when receiving files | Sets the default location for saving received files. | Choose a directory with sufficient space and easy access, such as a dedicated receiving folder. |
| Allow others to view file list | Allows connected remote devices to view the file list under the open path on this device. | Grants permission to browse files, but does not allow others to fetch them. Enabled by default when P2P is turned on. |
| Allow others to fetch files | Allows connected remote devices to download files from this device. | Enable only for trusted devices. |
| Allow others to delete file | Allows connected remote devices to delete files on this device. | High‑risk permission — not recommended unless absolutely necessary. |
| Allow others to rename file | Allows connected remote devices to rename files on this device. | Enable when collaboration is needed for file organization; disable once complete. |
| Allow others to create folder | Allows connected remote devices to create folders on this device. | Enable when the other party needs to save files in an organized manner. |
Notes
-
Deleting and renaming files are high‑risk operations. It is recommended to enable them only temporarily for trusted devices.
-
If you only need to receive files without exposing your file list, simply enable “Allow receive files from others” and configure the save path.
-
Do not set the save path to system directories or important data folders to avoid accidental impact on local files.
-
After permission changes, connected remote devices must reconnect for the new permissions to take effect.
