当前，一些设备在多个设备之间分享文件时，用户点击发送文件的设备A的击桌面图标中的隔空投送(Airdrop)功能图标后，在设备A的桌面上显示与设备A通信连接比如蓝牙、WIFI连接的一系列设备的名称列表，用户可以从该名称列表中选择接收文件的设备B，即可完成一对一的文件传输。然而，使用该方法完成跨设备之间的文件传输时，用户需要操作的步骤较多，尤其是当与设备A通信连接的设备较多时，用户就需要从常常的名称列表中找到接收文件的设备B。
比如，在一个具体的应用场景中，用户需要将设备A当前屏幕上显示的文档分享给设备B时，首先需要点击设备A当前屏幕上显示的分享图标，再选择隔空投送功能图标。这时，在设备A的屏幕上将显示与设备A蓝牙连接或WIFI连接的一系列设备的名称列表，用户需要从该名称列表中查找并选择要分享的设备B。在用户选择要分享的设备B后，设备B将接收到设备A传输的文档，并可以选择打开该文档的方式。在用户将设备A的文件分享到设备B的过程中，用户需要进行多次操作才能实现将文件从设备A传输到设备B，效率较低，用户体验较差。尤其是，当设备A周边存在多个设备，该多个设备与设备A通信连接时，用户需要从一长串的名称列表中找到设备B的名称，需要花费更多的时间，大大降低了用户的使用体验。
