Abstract: In a file sharing method, a transmitting-end device receives a selection operation performed on identifiers of multiple receiving-end devices that include a first device, a second device, and a third device. Triggered by the selection operation, the transmitting-end device sends a to-be-shared file to the first device. Thereafter, the transmitting-end device sends the to-be-shared file to the third device. The transmitting-end device then indicates to the first device to send the to-be-shared file to the second device, or indicating to the second device to obtain the to-be-shared file from the first device.

Abstract: This application provides a mirroring method, an apparatus, and a system. In the method, in a process in which an electronic device such as a mobile phone or a tablet and a large-screen device share an image resource through mirroring, a color gamut of a collected image resource may be converted into a color gamut obtained through negotiation between the electronic device and the large-screen device, the converted image resource may be sent to the large-screen device, and the large-screen device displays the image resource in the negotiated color gamut. According to the technical solutions provided in this application, the large-screen device may use a dynamic adaptive optimal color gamut during mirroring, that is, a color difference between the image resource displayed on the electronic device and the large-screen device may be reduced in the mirroring process. This improves users' visual experience during mirroring.

Abstract: Embodiments of this application provide a multi-window display method, a first electronic device, and a second electronic device. The method is applied to the first electronic device and the second electronic device that communicate with each other. When a plurality of applications run on a mobile phone, a plurality of windows of the mobile phone can be displayed on a PC, and each window is correspondingly used to display a different application. A user can perform an operation on each mobile phone application by using a window that corresponds to the mobile phone application and that is displayed on the PC. In addition, the operation performed by the user on the mobile phone application on the PC does not affect use of another function of the user on the mobile phone. This improves office efficiency such as file sharing, and improves user experience.
