The controller executes step S12 to determine whether a thumbnail of the file is recorded in the thumbnail list;

judging whether the thumbnail of the file is recorded in the thumbnail list or not;

for example, in one possible embodiment, a file and a thumbnail of the file may be configured with a corresponding identifier. The controller searches for a thumbnail matched with the identifier in the thumbnail list based on the identifier of the file;

for example, in a feasible embodiment, 4 thumbnails are recorded in the thumbnail list, which are respectively: thumbnail 1, thumbnail 2, thumbnail 3, thumbnail 4, and the specific thumbnail list can refer to table 2;

TABLE 2

Serial number	File name	Identification	Remarks for note
				1	Thumbnail 1	Identification 1
2	Thumbnail 2	Identification 2
				3	Thumbnail 3	Identification 3
4	Thumbnail 4	Sign 4

The controller passes through the table 2 based on the identifier (identifier 1) of the file 1, and determines that the thumbnail of the file 1 is recorded in the table 2; then, the controller traverses table 2 based on the identifier (identifier 2) of file 2 to determine that thumbnail images with file 2 are recorded in table 2 … … the controller traverses table 2 based on the identifier (identifier 5) of file 5 to determine that thumbnail images with file 2 are not recorded in table 2.

For another example, in order to reduce the amount of data stored in the thumbnail list, in a feasible embodiment, the file name may be used as an identifier, and the specific thumbnail list may refer to table 3;

TABLE 3

Serial number	File name	Remarks for note
			1	Document 1.png
2	Document 2.png
			3	File 3.png
4	Document 4.png

For another example, in some feasible embodiments, the thumbnail list and the file may be stored in the same folder, in which case the thumbnail and the file are not allowed to use the same name, and based on this application, a naming manner of the thumbnail is shown, where the particular naming manner is that the name of the thumbnail is the storage address of the file + the name of the file, and the particular thumbnail list may be referred to

Table 4;

serial number	File name	Remarks for note
			1	Photo _ person _ file 1.png. bmp
2	Photo _ person _ file 2.png. bmp
			3	Photo _ person _ file 3.png. bmp
4	Photo _ person _ file 4.png. bmp

The advantages brought by the above nomenclature are described in detail in the schemes hereinafter.

In the practical application process, the implementation manner of determining whether to record the thumbnail of the file in the thumbnail list may be, but is not limited to, the above several manners, and the applicant does not make much limitation herein.

If the thumbnail of the file is recorded in the thumbnail list, the controller performs the step S13 to control the display to show the thumbnail at the file display position, and the controller continues to perform the step S11.

The file display position is determined by the icon size set by the user and the size of the display interface. FIG. 9 is a schematic diagram of a display presentation interface according to one possible embodiment. In the embodiment shown in fig. 9, the user-set icon is displayed in the form of an oversized icon, at this time, 8 icons may be simultaneously displayed on the display interface of the display, and the display interface is divided into 4 × 2 areas, where each area is a display position of one file. Area a in fig. 9 is a display area of document 1.

If the thumbnail of the file is not recorded in the thumbnail list, the controller performs the step S14 to control the display to show the preset icon at the file display position, and the controller continues to perform the step S11.

The scheme shown in the embodiment of the present application does not limit the style of the preset icon.

The icons shown in the folders 4, 5, 7, and 8 in fig. 9 are merely exemplary styles for showing one preset icon, and the style of the preset icon in the process of practical application may be, but is not limited to, the style shown in fig. 9.

If the thumbnail list records thumbnails of the files, the controller is configured to perform step S104 of controlling the display to show the thumbnails at the file display positions;

if the thumbnail list does not record the thumbnail of the file, the controller is configured to perform step S105 of controlling the display to show a preset icon at the file display position;

the following describes in detail the operation process of the display device shown in this embodiment with reference to specific examples.

In a feasible embodiment, the user selects folder 1, where folder 1 contains 8 files, namely file 1, file 2, file 3, file 4, file 5, file 6, file 7, and file 8; the thumbnail list corresponding to the folder 1 is the thumbnail list 1. In response to the user selecting the folder 1, the controller traverses the thumbnail list 1 based on the name of the file 1, determines that the thumbnail of the file 1 is recorded in the thumbnail list 1, and controls the display to display the thumbnail of the file 1, at this time, the display interface of the display can refer to the interface 11 in fig. 10; then, the controller traverses the thumbnail list 1 based on the name of the file 2, determines that the thumbnail of the file 2 is recorded in the thumbnail list 1, and controls the display to display the thumbnail of the file 2, at this time, the display interface of the display can refer to the interface 12 in fig. 10; then, the controller traverses the thumbnail list 1 based on the name of the file 3, determines that the thumbnail of the file 3 is not recorded in the thumbnail list 1, the controller controls the display to display a preset icon, at this time, the display interface of the display may refer to an interface 13 … … in fig. 10, the controller traverses the thumbnail list 1 based on the name of the file 8, determines that the thumbnail of the file 8 is not recorded in the thumbnail list 1, and the controller controls the display to display the preset icon, at this time, the display interface of the display may refer to an interface 14 in fig. 10.

This completes the description of the present embodiment.

The original purpose of the technical scheme design that this implementation provided is when waiting to show the file for the media file, can show this file with the form of thumbnail to play the effect of suggestion to the user. If the type of the file is a non-media asset type, the controller continues to traverse the thumbnail list, which is definitely a waste of computing resources of the controller.
