The present invention relates to a method for synchronizing folder information. More particularly, the present invention relates to folder information between a PC and a mobile device, which can be applied by matching a tree structure of a folder of files stored in a PC set according to user convenience in a mobile device. To synchronize.

Among mobile devices having a playback function, MP3 players store audio files, such as music compressed in a specific format, in a memory, unlike a player playing a cassette on a conventional cassette audio device, and then listen as needed. Finding and playing the corresponding music file has the advantage of simply listening to the music file.

In addition, in recent years, as a portable storage device as well as an MP3 player function, it can replace USB memory to store data in the memory of the PC without a separate application, and insert the data into the USB port of the PC in another place to read or play the data. There is a tendency to add various functions such as playing a file.

Such a portable media playback device cannot use the drag and drag method of importing folder information of a PC environment, and cannot import folder information of stored files.

Therefore, there is a problem that the user has to rearrange the files individually downloaded and stored in the PC.

MP3 files stored in the MP3 player have a header, and commercially available models have a function of storing information such as the artist, song title, album, training, and comment of the song file in the ID3Tag located in the file header. If the ID3Tag information does not exist in the file stored in the mobile device, there is a problem that the mobile device is automatically stored in an unintended location.

In addition, media files can be automatically classified according to the tag information, but other data formats (txt, ppt, doc, ...) are difficult to classify automatically because they do not have tag information. . In this case, if there are a lot of etc files, there is a problem that it is not easy to search for a file.

Therefore, there has been a demand for a method of easily finding a file on a mobile device by setting a tree structure of a folder stored in a PC familiar to a mobile device.

The technical problem of the present invention is to provide a method of synchronizing folder information between a PC and a mobile device to more easily find a desired file location by setting information of a familiar PC folder set up according to a user's preference in correspondence with a mobile device. There is.

Method for synchronizing folder information between a mobile device and a PC having a memory according to the present invention for achieving the above technical problem,

Selecting a file to be stored in the mobile device on the PC;

Acquiring upper folder information on the PC for the file;

Determining whether it is set to a database recording type;

If the database recording type is set, recording folder information of the file to the mobile device;

Downloading the file to a mobile device; And

And displaying the corresponding file on the screen of the mobile device by matching the file with the folder information on the PC by using the folder information according to the file user arrangement selection.

In addition, the process of acquiring folder information in the PC may be characterized in that acquiring corresponding file information using an application programming interface of the PC.

In addition, when not set to the database recording type, characterized in that it comprises the step of recording the folder information of the file in the header of the file.

In addition, the process of recording the folder information in the header of the file is characterized in that the recording in the header of the file.

In addition, the mobile device is characterized in that the portable media playback device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a file stored in a folder of a tree structure on a general PC window, Figure 2 shows an MP3 file header in which the folder information of the file according to the present invention is stored. 3 is a diagram illustrating a folder information table of a file stored in a database of a mobile device according to the present invention.

In the present invention, as shown in Fig. 1, the x.mp3 file and the w.txt file in the folder of the tree structure on the PC window are constituted as headers of the x.mp3 file and the w.txt file, for example, ID3v2, which is a header format of a typical media file. You can save the folder information of the file as Root: \ A \ B \ C \ x.mp3 and Root: \ A \ B \ C \ K \ w.txt, respectively. It may be.

 In addition, as shown in FIG. 3, folder information of an x.mp3 file and a w.txt file may be stored as a table in which a file type, a file name, a path, and the like are recorded in a database of the mobile device.

4 is a flowchart illustrating a method of synchronizing folder information according to the present invention.

When the user's PC is in the Windows environment, when the Windows file system composes the folder tree shown in FIG. 1, files to be downloaded to the portable playback device, such as W.txt and x.mp3, are selected from the folder tree (step 400). In step 402, each upper level file of the corresponding W.txt and x.mp3 files is read. At this time, parents of W.txt and x.mp3 files can be set up to a specific root that can be designated by the user, and the file information can be read using the application programming interface.

If the mobile device is set to the type of recording file information in the database, the folder information of the file is recorded in the database of the mobile device as shown in FIG. 3 (steps 404 and 406). Applications such as Samsung Media Stewardess, which is applied to Samsung MP3 players, can also write to the database even when the media files are stored on the mobile device.

On the other hand, if it is not set to the type of recording the file information in the database in step 404, each Root: \ A \ B \ C \ respectively in the padding portion constituting the ID3v2 header of the file, as shown in FIG. The folder information of the file is stored as x.mp3 and Root: \ A \ B \ C \ K \ w.txt (step 406). In this case, it may be stored in a place such as ID2Tag or Iyric3 that is configured as a header of the file.

In step 410, the file is downloaded from the PC to the mobile device. If the file is set as a user alignment option in the mobile device (step 412), the file is displayed on the screen of the mobile device using the folder information of the downloaded file, that is, the folder information stored in the database or the header of the file. In operation 416, the PC and the mobile device are displayed as a tree structure of the same folder based on the root selected by the user. In particular, when providing various screens through the user sorting option of a file, it is more efficient to display the screens logically rather than physically creating and showing the structure.

In operation 414, when the option of user alignment of the file is not set, the same screen as the prior art may be output as a default.

Here, the format of the data among the files synchronized in the PC includes TXT, MP3, WMA, WMV, PPT, etc., all data downloaded from the PC to the mobile device.

FIG. 5 illustrates screens of a PC and a mobile device displayed in correspondence with file information of the PC by the flowchart of FIG. 4.

Selecting a folder or file on the screens 512 to 516 of the portable media playback apparatus that is a mobile device corresponding to the folder structure displayed on the PC screen 510 facilitates the user's own folder structure. You can access the file and play it.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

According to the present invention, there is provided a method of synchronizing folder information between a PC and a mobile device that can easily find a desired file location by setting information of a familiar PC folder set up according to a user's preference in correspondence with a mobile device. .
