FILE TRANSMISSION METHOD AND RELATED DEVICE

Embodiments of the present invention disclose a file transmission method and a related device, which are applied to a first device in a multi-device collaboration system. The multi-device collaboration system includes N devices. Any device in the N devices establishes a collaboration with at least one another device in the N devices. The first device is any device in the N devices. N is an integer greater than 2. The method includes: The first device displays a first interface; the first device receives a first drag operation performed on the first interface for a target file; the first device notifies another device in the N devices to monitor a release position of the first drag operation; the first device detects the release position of the first drag operation; and the first device controls the target file to be sent to a device in the N devices that matches the release position. Multi-device file transmission can be implemented by using embodiments of the present invention, thereby improving file transmission efficiency in multi-device collaboration and simplifying user operations.
