具体实施方式
以下结合附图对本申请的示范性实施例做出说明，其中包括本申请实施例的多种细节，应当将它们认为仅仅是示范性的。
本申请的执行主体可以是任一电子设备，例如，终端设备，包括但不限于用户设备(User Equipment，UE)、移动设备、蜂窝电话、无绳电话、个人数字助理(Personal Digital Assistant，PDA)、手持设备、计算设备、车载设备、可穿戴设备等。在一些可能的实现方式中，该方法还可以通过处理器调用存储器中存储的计算机可读指令的方式来实现。
本申请技术方案可以应用于第一电子设备，第一电子设备的操作系统可以是Android操作系统，涵盖Google发行的Android OS以及安卓开放源代码项目(Android Open Source Project，AOSP)和基于AOSP的多种衍生系统，如MIUI、EMUI、One UI等。
图1为本申请一实施例中扩容方法的示意图。如图1所示，该方法可以包括：
步骤S101，获取远程挂载信息，远程挂载信息包括远程文件系统所在的第二电子设备的属性信息、第二电子设备存储的源文件夹的存储路径和第一电子 设备存储的目标文件夹的存储路径。
第一电子设备可以接收用户输入的远程挂载信息。远程挂载信息包括安装了远程文件系统的第二电子设备的属性信息。属性信息可以包括但不限于第二电子设备的网际互联协议(Internet Protocol，IP)地址、端口号、用户账号和密码。远程挂载信息还包括了第二电子设备存储的源文件夹的存储路径和第一电子设备存储的目标文件夹的存储路径。其中，第二电子设备也可以是网络存储空间，相应的，属性信息可以是网络存储空间的存储地址等。
在一种可能的实现方式中，远程文件系统包括以下至少一项：用户空间文件系统(File system in Userspace，FUSE)或网络文件系统(Network File System，NFS)。
其中，使用FUSE可以像使用可执行二进制文件一样来开发文件系统。FUSE具有简单的应用程序接口(Application Programming Interface，API)库，可以被非特权用户访问，并可以安全的实施。NFS是一种分布式文件系统，可以实现客户端主机访问服务器端文件，并且客户端主机访问服务器端的过程与客户端主机访问本地存储的过程一样。NFS是基于用户数据报协议(User Datagram Protocol，UDP)/IP的应用，其采用远程过程调用(Remote Procedure Call，RPC)机制。RPC提供了一组与机器、操作系统以及低层传送协议无关的存取远程文件的操作。RPC支持外部数据表示法(External Data Representation，XDR)。XDR是一种与机器无关的数据描述编码的协议，他以独立于任意机器体系结构的格式对网上传送的数据进行编码和解码，支持在异构系统之间数据的传送。

预先生成并存储远程文件系统的传输协议可执行文件，在获取到远程挂载信息之后，通过接口调用传输协议可执行文件。
传输协议可执行文件可以是安全外壳协议文件系统(Secure Shell File System，SSHFS)可执行文件，也可以是NFS可执行文件。
步骤S103，基于传输协议可执行文件和远程挂载信息，将源文件夹和目标文件夹进行关联，以实现第一电子设备的扩容。
