SHAREit v.5.1.0.7

Yes. SHAREit uses a local wireless connection between the participating devices, so an active Internet connection is not required. Make sure Wi-Fi is enabled on both devices and keep them within a reasonable wireless range.

Check that SHAREit is running on both devices and that they are connected to the same wireless network or transfer session. If the devices still cannot connect, temporarily check the Windows firewall settings, disable any active VPN connection, and restart SHAREit.

Yes. Select the required files before starting the transfer. In a standard Windows file dialog, hold Ctrl while clicking individual files to select multiple items, or select a complete folder when supported.

SHAREit normally creates copies on the receiving device. The original files remain on the sending computer unless you delete them separately.

Keep both devices awake and avoid changing the wireless network during the transfer. Reconnect the devices in SHAREit and start the operation again. Large transfers are more reliable when unnecessary network-intensive applications are closed.

Yes, provided that the compatible SHAREit application is installed on both devices. Open the application on the PC and smartphone, establish the connection, and then select the files or folders to send.

Routine file transfers do not generally require a separate online account. The devices must still be connected through SHAREit, and the receiving device may need to accept the incoming transfer.
