[0040] In addition, please refer to FIG. 6, a method for using the aforesaid movable storage device in an intelligent terminal is further provided, and the method comprises steps in the following:

[0041] Step 110, when a movable storage device is accessed, detecting whether the movable storage device has a unique identifier or not.

[0042] Specifically, only when the detected unique identifier is correct, the APP (Application) software operating on the intelligent terminal can be activated; otherwise, the APP software can't be activated. For example, only when a serial number of an inserted OTG movable storage device is included in a pre-designed serial number list, said serial number can be identified, and the APP software of the intelligent terminal can be used.

[0043] Step 120, scanning and classifying data stored in the movable storage device, and generating a plurality of external classified groups.

[0044] Furthermore, the method further comprises a step of scanning and classifying data stored in an internal storage device of the intelligent terminal, and generating a plurality of internal classified groups. That is, searching in the internal storage device and the external storage device, and performing unified management for corresponding documents, which includes a group comprising pictures, musics, videos, files, E-books, address books, or the like.

[0045] Step 130, generating icons matching with the plurality of external classified groups, and then mapping and linking the external classified groups with the icons corresponding to the external classified groups.

[0046] Furthermore, the method further comprises a step of generating a plurality of icons matching with the internal classified groups, and then mapping and linking the internal classified groups with the icons corresponding to the internal classified groups.

[0047] Even further, the method further comprises the following steps:

[0048] generating a first back-up icon; when an external instruction is received, generating a folder matching with the internal classified groups in the movable storage device, and synchronizing the internal classified groups in the internal storage device into a corresponding folder for back-up or replying;

[0049] generating a second back-up icon; when an external instruction is received, generating a folder matching with the external classified groups in the internal storage device, and synchronizing the external classified groups in the external storage device into corresponding folder for back-up or replying.

[0050] In this way, unified management for data in the internal storage device and the external storage device can be performed using the aforesaid generated icons.

[0051] As shown in FIG. 7, in a holistic architecture of the APP software (the aforesaid application method), a very intuitional icon hierarchical user interface is used. A first hierarchy is an icon of OTG Drive APP, after it is clicked, a second hierarchy is entered, wherein the second hierarchy includes two modules, that is, an internal storage area and an external storage area. The internal storage area directly manages some documents stored in the portable device itself, this is a third hierarchy which includes modules of pictures, musics, videos, documents, E-books, address books, or the like. Various documents are managed graphically and human-friendly using APP software, which is convenient and practical, and user experience can be improved. The external storage area is the one which corresponds to the internal storage area and lies in the third hierarchy too. The external storage area refers to an added storage area configured to connect the portable device to external, and a USB Type-C OTG storage device is one example of the external storage area. The external storage area is managed graphically and human-friendly using APP software too, when the internal storage space is not enough or the internal storage space cannot be used, pictures, musics, videos, and other application documents coming from the external can also be shared by the user. Of course, various sharing functions such as mutually sharing and mutual file transmission between the internal storage area and the external storage area can be totally supported, such that a sharing mode without any obstacles can be performed between pictures, musics, videos and various documents in the portable device and pictures, musics, videos, and various documents in the external storage area.

[0052] Charm of the APP software is that the APP software makes man and machine be combined as one, each application is decomposed by hierarchical icons, lots of complicated and repeated procedures are reduced, and an interactive experience can be brought to the user.

[0053] In contrast with an existing mobile device file manager, advantages of our APP software lies in:

[0054] 1. a visual graphic operation interface is provided. A corresponding document can be found by directly clicking an APP icon, documents are sorted automatically and managed according to preset categories, and copying, transmission and broadcast for the documents can be realized between the internal storage device and the external storage device. However, when a file manager of existing mobile device is opened, various documents are complicated, and it is really difficult for the user to find out a required documents.

[0055] 2. The operation is more convenient and simple, and both time and effort are saved. Category of APP software is clear, and the icons are concise. Document(s) needed by the user can be found very conveniently and quickly by clicking icon(s) corresponding to the document(s). However, the file manager of the existing mobile device needs to open many folders to find corresponding document(s).

[0056] 3. a specialized APP has much more value-added function software, such as the functions of one key recovery, back-up of address book, E-book, private cloud, or the like.

[0057] The aforementioned embodiments are only preferred embodiments of the present invention, and should not be regarded as being any limitation to the present invention. Any modification, equivalent replacement, improvement, and so on, which are made within the spirit and the principle of the present invention, should be included within the protection scope of the present invention.
