## Abstract

This application relates to a file opening method and a device. A first device displays a first interface, and projects the first interface onto a second interface of a second device, where the first interface includes at least one file icon, the second interface includes the first interface, and a file corresponding to the at least one file icon is stored in the first device. The first device detects an operation performed on the file icon. When the file icon is an icon displayed on the first interface, the first device invokes a first application to open the file; or when the file icon is an icon displayed on the second interface, the first device sends metadata of the file to the second device, where the metadata of the file is used to open the file on the second device.
