Back folder attachment for accessing extended storage and system and method thereof

Abstract

The invention discloses a back folder attachment for accessing extended storage and a system and a method thereof. The system for accessing extended storage comprises a first terminal, a second terminal and a back folder attachment; when back folder attachment detects the access of the first terminal, the first terminal is set as the primary device, and the first terminal can then access the memory card inside the back folder attachment, in order to expand the storage space of the first terminal; when back folder attachment detects the accesses of both the first terminal and the second terminal, the first terminal is set as the secondary device, and the second terminal is set as the primary device, and the second terminal can then access the memory card inside the back folder attachment and the memory of the first terminal. In this way, the function of extending the external storage card of the first terminal can be achieved, and the user is provided the convenience to use the second terminal and to access the data in the first terminal and in the memory storage card of the back folder attachment at the same time. Thus the problems that the current back folder attachment cannot access two terminals at the same time, and one terminal cannot at the same time access the storage space of the back folder attachment and the storage space of another terminal are solved.

Description

technical field [0001] The invention relates to the technical field of back clip accessories, in particular to a back clip accessory for accessing extended storage, a system and a method thereof. Background technique [0002] At present, there are more and more types and functions of the back clip accessories of the second terminal.
