For convenience of explanation, in the embodiment of the present application, the software application is referred to as a "file management application".

Fig. 8 is a schematic diagram illustrating an implementation scenario according to an exemplary embodiment of the present application. As shown in fig. 8, in this scenario, the display device 200 and the server 300 are included, the display device may communicate with the server to implement interaction, the display device has an external device interface, and may be connected to an external device 801, such as a usb disk, an SD card, a mobile hard disk, a user mobile phone, and the like, subject to the hardware function of the server, and the number of the servers may be one or multiple. The user can log in the cloud account through the display device, and then access the cloud server 802, upload local data to the cloud or download the cloud data to the local.

In some embodiments, the controller of the display device is configured to present a user interface on the display including a file icon for the at least one file; responding to a sharing operation for sharing at least one target file, and sending the target file and corresponding data information (such as a unique identifier) to a server, wherein the target file is a file selected from at least one file for sharing; receiving a page address returned by the server, and generating a sharing code according to the page address, wherein the sharing code is used for accessing the page address, and the page address points to a page including target file information; presenting the sharing code on a display.

Therefore, other optional terminal devices can access the page containing the target file information by scanning the sharing code, so that the target file is acquired or checked, the user operation is simple, a plurality of files can be shared for the plurality of terminal devices at the same time, and the method is convenient and fast.

An embodiment of the present application further provides a method for sharing a file, where a controller of a display device is configured to execute some or all of the steps of the method, and fig. 9 is a flowchart of a method for sharing a file according to an exemplary embodiment of the present application, and as shown in fig. 9, the method may include:

step 901, presenting a user interface on a display, wherein the user interface comprises a file icon of at least one file.

In one possible scenario, when the display device detects an operation of opening a "file management application" by a user, or when the user clicks a function icon in an interface of the "file management application", a presentation instruction is generated, and the presentation instruction is used for instructing to present a file available for sharing in the user interface.

The file management application receives the presentation instruction, and determines at least one file available for sharing in response to the presentation instruction, wherein the file available for sharing includes a local file and/or a cloud file, and the local file includes a display device local file and/or an external device local file. The file may be in a format of a picture type, a format of a document type, a format of a video type, a format of an audio type, and the like.

In specific implementation, in the first aspect, the "file management application" may traverse local data of the display device, specifically may traverse data of the display device under a locally specified storage path, and screen out a file that can be shared from the traversed data; in the second aspect, the file management application detects whether the external equipment is connected with the display equipment, and if so, traverses the local data of the external equipment and screens out the files which can be shared; in a third aspect, the file management application accesses the cloud server by using the specified cloud account, traverses the cloud data under the cloud account, and screens out the cloud files available for sharing.

It should be noted that the present application does not limit the rule for screening the files available for sharing. For example, a file in the format of a picture type may be screened out as a file to be shared according to the file format, and a file in the format of a picture type and a file in the format of a document type may be screened out as a file to be shared.

And after determining at least one file available for sharing, generating a user interface containing file icons of the file available for sharing. Finally, the user interface is presented on a display.

It should be noted that the file icon includes a thumbnail, specifically, if the file available for sharing is a picture file, a corresponding thumbnail may be displayed in the user interface, and if the file available for sharing is a video file, a thumbnail of a video cover may be displayed in the user interface.

It is further noted that the user interface further comprises function icons, such as icons pointing to batch selection functions.

Illustratively, FIG. 10a illustrates a user interface. As shown in fig. 10a, the user interface displays 10 file icons of the selectable files, and the user can scroll the user interface by moving the scroll bar on the right side to bring other views into the screen display area. The user interface also displays a function icon of 'batch operation', and when the user clicks the icon, the file icon in the user interface enters a selectable state.

And 902, when batch selection operation is detected, updating the user interface, wherein the file icon is in a selectable state in the updated user interface.

Continuing with the above example, the user may enter a batch selection operation by moving focus to "batch operation" and confirming via the remote control. When a batch selection operation is detected, the current user interface is updated, so that each file icon in the updated user interface is in a selectable state, as shown in fig. 10 a. In fig. 10b, the user can input the selected operation by moving the focus to the file icon of the target file and confirming it through the remote controller.

And step 903, recording the selected target file when the selection operation for selecting the target file is detected.

In particular, the file name, file type, storage path, etc. of the target file may be recorded.

Step 904, when a sharing operation for at least one target file is detected, sending the target file and corresponding data information to a server.

As can also be seen from fig. 10b, in the case that at least one file available for sharing is selected by the user to become the target file, the function icon of the user interface "generate sharing code" is activated. The user inputs a sharing operation for the selected target file by selecting and confirming the function icon.

In a specific implementation, step 904 may include the steps shown in fig. 11:

and step 111, acquiring the unique identifier of each target file.

In some exemplary embodiments, the data information may be a unique identifier, also referred to as a media asset ID, which is unique within the database of the server for distinguishing files in the server. The unique identifier is allocated to the file by the server, specifically, the display device sends the file name, the file type and the local storage path of the file to the server, and after the server receives the file, a string of unique characters, namely the unique identifier of the file, is generated and then returned to the server. Meanwhile, the server side and the display equipment side can correspondingly store the file name, the file type, the local storage path of the file and the assigned unique identifier of the file so as to be convenient for query.

In an embodiment scenario, for some files, the server has already allocated a unique identifier for the file and saved in the local data of the display device, and the target file may be any one of a local file of the display device, a local file of the external device, and a cloud file, and further, according to a specific situation of the target file, a manner of acquiring the unique identifier is different, specifically:

firstly, whether a unique identifier corresponding to the file name of the target file exists in local data is searched. During specific implementation, a data list is created in advance and stored in the local display device, and the data list is used for correspondingly storing the file name and the unique identifier of the file; when the unique identifier of the file returned by the server (including the cloud server) is received, correspondingly storing the file name and the unique identifier of the file in the data list.
