According to an embodiment of the invention, the external storage device may be a USB storage device connected to a universal serial bus (USB) of the display system. In step S11, the USB port of the display system can be detected. When it is detected that the USB device is accessed, it is determined whether the USB device is a USB storage device. If it is not a USB storage device, the next detection is performed after waiting for a predetermined period; if it is a USB storage device, the list of files in each USB storage device is sequentially acquired in a predetermined order.

According to an embodiment of the invention, the predetermined period may be 3 to 6 seconds in order to acquire list information of files in the external storage device in time.

In order to facilitate different processing of the classified files, the display system may include an operation area and a play area. In step S3, the step of importing the classified file list into the display system may include: importing at least a part of the classified file list into a play area of the display system or importing the classified file list into an operation area of the display system.

The operation area can correspond to a specific folder in the display system. When the classified file list is imported into the operation area, the file can be moved, deleted, modified, and the like. The playing area may be a playing unit used by the display system to play files. When the classified file list is imported into the playing area, the file may be played and the like, for example, the content of the file is played by using the audio and video playing software.

It should be noted that the file list of the operation area of the import display system can be further imported into the play area for playback. That is to say, after the files in the external storage device are classified, the classified file list can be imported into the operation area to modify the file, etc. The operation is then imported into the play area for playback; or the classified file list can be directly imported into the play area for playback.

Fig. 4 shows a detailed flow chart of step S3 shown in Fig. 1. As shown in FIG. 4, step S3 may include:

Obtaining a user's instruction (S31);

When a first instruction corresponding to the play area is obtained, at least a portion of the classified file list is imported into the play area (S32);

When the second instruction corresponding to the operation area is obtained, the classified file list is imported into the operation area (S33).

The user can issue a first instruction to import the classified file list into the play area for playback; the user can also issue a second instruction to import the classified file list into the operation area to modify the file. The classified file list may be a file, an audio file, or the like that can be displayed (or played), and may also include files that cannot be used for presentation, such as application files. In the file management method according to the present invention, when the classified file list is imported into the play area, only files that can be displayed (or played) can be imported into the play area, and files that cannot be displayed (for example, application files) are not processed. , thereby reducing the number of files imported into the play area, so that the user can find the file to be processed.

Further, as shown in FIG. 4, after the classified file list is imported into the display system, the file management method according to the present invention may further include displaying a file list in the play area and/or the operation area (S34).

As described above, the list information of the file can be obtained first, and the files are classified according to the list information. According to an embodiment of the present invention, the list information may include a file name and a file format. In the above step S2, the files may be classified according to a file format, and the classified files may include a picture file and a non-picture file. When the file list in the play area is displayed, if the file is a picture file, the thumbnail of the picture file is displayed; if the file is a non-picture file, and the preset folder includes the same picture as the file name of the non-picture file The file displays a thumbnail of the image file having the same file name as the non-picture file; if the file is a non-picture file, and the preset folder does not include the same image file as the non-picture file, the display Corresponding to the non-image file Preset icon. Displaying a list of files as thumbnails visually shows the contents of an image file or a non-image file.

When the file management method according to the present invention is applied to management of a multimedia file, as shown in FIG. 5, files in the external storage device may include a picture file, an audio file, and a video file. When the user issues the second instruction, the classified file list may be imported into the corresponding position of the operation area; when the user issues the first instruction, the file type in the file list is determined by the file format, and the file list is performed as described above. display. That is, when the file is a picture file, a thumbnail of the picture file is displayed; when the file is an audio file or a video file, the preset folder may be searched for whether there is a picture with the same file name as the audio file or the video file. The file, if present, displays a thumbnail of the image file with the same file name as the audio file or video file, and if not, displays the preset icon.

The preset folder can be a folder that is preset in the display system. A plurality of image files can be included in the preset folder. The present invention is not limited to the setting of the preset icon, and the preset icon may be an icon set by the user, or may be a default icon of the system. The example of FIG. 6 shows an icon that can be displayed in the play area, for example, the preset icon corresponding to the audio file may be a headphone icon, and the preset icon corresponding to the video file may be a video icon.

In addition, the present invention has no limitation on the manner of displaying the file list in the operation area, and may be displayed in the same manner as the play area, or may be displayed in the manner of a text or a unified icon, as long as the file in the external storage device can be displayed according to the display. You can view, move, delete, etc.

When the file list in the external storage device is imported into the play area of the display system and the imported file list is displayed, the resources of the display system are occupied. As the list of displayed files increases, the more resources are occupied. In order to reduce the occupation of the resources of the display system, the above step S32 may include:

Storing the classified file list in the database (S32a);

A file list of the number of files corresponding to the third instruction is read in the database according to the third instruction of the user, and the file list read according to the third instruction is imported into the play area (S32b).

As described above, the user instructions may include a first instruction corresponding to the play area and a second instruction corresponding to the operation area. In addition, the user's instructions may further include a third instruction, which may include a page up instruction, a page down instruction, a pull up instruction, a pull down instruction, and the like.

The operation performed for the user's third instruction will be described below with an example.

First, the file list in the external storage device is stored in the database, assuming that M files are included in the file list. At this time, the page counter K=0, and it is assumed that each page includes N files.

When the user's third instruction is a page down instruction, the value of the page counter K is incremented by 1, but does not exceed M/N. When the user's third instruction is a page down instruction, the value of the page counter K is decremented by 1, but not less than zero.

When the user performs a page turning operation, the file list of the N*K+1th N*K+N files (total N files) is read and introduced into the play area for display. That is, the number of files in the file list of each time you import the playback area is N.

While the play area displays the file list of the N files, the file list of the n files after the N files being displayed and the file list of the n files before the N files are displayed are read. When the user's third instruction is a pull-down instruction, the playback area is imported for display by the following (Nn) files of the N files being displayed and the n files following the N files being displayed (total of N files) ) a list of files. When the user's third instruction is a pull-up instruction, the playback area is imported for display by the n files preceding the N files being displayed and the preceding (Nn) files among the N files being displayed (N total) File) a list of files.

For example, an external storage device includes M=300 picture files, assuming N=20, n=5. According to the above manner, the file list of 300 picture files is first stored in the database, and the file list of the 1st to 20th picture files is displayed in the play area (that is, the thumbnails of the 1st to 20th picture files are displayed). ). After several user operations, the file list of the 31st to 50th files (total N=20 files) is imported into the play area for display. At this time, when the third instruction of the user is the page up instruction, the file list of the 11th to 30th files (total N=20 files) is imported into the play area and displayed (ie, the 11th to the Thumbnail of 30 picture files); or, when the user's third finger When the page down command is commanded, the file list of the 51st to 70th files (total N=20 files) is imported into the play area and displayed (ie, thumbnails of the 51st to 70th picture files are displayed) Or; when the user's third instruction is a pull-up instruction, the file list of the 26th to 30th files (total n=5 files) is imported into the play area, and the 46th to 50th files are The file list is removed from the play area, and the file list of the 26th to 45th files (total N=20 files) is displayed (ie, the thumbnails of the 26th to 45th picture files are displayed); or, when When the third instruction of the user is a pull-down instruction, the file list of the 51st to 55th files (n=5 files) is imported into the play area, and the file list of the 31st to 35th files is moved from the play area. Except, and the file list of the 36th to 55th files (total N=20 files) is displayed (that is, the thumbnails of the 36th to 55th picture files are displayed).

In this way, the file list that is imported into the play area each time is only a part of the file list of all the files in the external storage device, and thus the occupied resources can be reduced.

In order to make the display of the file list more consistent, it is possible to read the file list of the n files before the N files being displayed and the n files after the N files are being displayed while displaying the file list of the N files. List of files.

According to the above example, while the file list of the 51st to 70th files is displayed, the file list of the 45th to 50th files and the file list of the 71st to 75th files can be read. Thus, when the user's third instruction is a pull-up instruction or a pull-down instruction, the file list of n=5 files has been read, thereby shortening the time for updating the display, making the display more coherent.

When the classified file list is imported into the play area of the display system, the classified file list may be first stored in the database, and the number of files of the file list imported into the play area may correspond to the user's instruction, and thus, Divide the file list into multiple playback areas for display, saving resources.
