Description

How to search folders for MP3 playback {METHOD FOR FOLDER SEARCHING OF MP3 PLAY}

The present invention relates to a folder search method for MP3 playback. In particular, when an MP3 file folder to be played is selected, a subfolder is repeatedly searched to automatically generate a list of MP3 files to play all songs without searching for additional files or folders. The present invention relates to a folder search method for MP3 playback.

Recently, thanks to the development of digital signal processing and semiconductor integrated technology, new products based on digital signal processing are gradually being released. Existing audio products could not escape physical constraints. But MP3's new concept of audio algorithms has overcome existing constraints to make our lives easier.

MP3 is a technique used for audio only by extracting the digital audio data compression part which is a part of MPEG compression algorithm. This compressed MP3 data has a compression effect of up to 12 times that of the conventional CD data amount. In terms of sound quality, it has a sound quality similar to that of CD, and has a high sound quality indistinguishable from human hearing. The product is currently being released under the name MP3 Player, which is popular with many people, and the demand is expected to increase explosively. It takes a lot of work to decompress MP3 compressed data and listen to it with our ears.

In addition, it is also important for a user to easily search for and play a folder in which the MP3 file is compressed. Therefore, in the related art, in order to select a folder to be played by searching in a PC, a portable or car MP3 file folder, or to make a list, a desired folder is selected and listed in the MP3 file folder.

The method of making a list by selecting the desired MP3 files has the advantage that only the desired songs can be made and played back. However, in the case of a portable or car MP3 player, it is inconvenient and difficult to select the desired songs one by one. There is a hassle to choose.

In addition, the method of selecting a folder to be played by searching the folder and listing the MP3 files in the selected folder is easy to implement and does not need to select files one by one, but a module for selecting a folder is required because a folder must be selected. In addition, if MP3 files of multiple folders are stored separately, there is a disadvantage in that the user has to move around by searching for a desired folder.

In addition, if there is no MP3 file in the selected folder and the MP3 file of the selected folder has only a file name of MP3 and the actual content is not an MP3 file, all MP3 files in the folder need to be identified as correct MP3 files.

The present invention was created to solve the above problems, and when selecting an MP3 file folder to play, it searches for subfolders repeatedly and automatically generates a list of MP3 files to play all the songs without searching for additional files or folders. An object of the present invention is to provide a folder search method for MP3 playback.

1 is a flowchart of a folder searching method for MP3 playback according to the present invention;

2 is a view for explaining an embodiment of a folder search method for MP3 playback according to the present invention.

Folder search method for MP3 playback according to the present invention to achieve the above object,

Searching for an MP3 file in an upper root folder;

Storing the MP3 file in a list when the file is found in the searching step;

Determining whether a subfolder to be searched exists;

Searching for an MP3 file in the subfolder if the subfolder exists in the step of determining whether the subfolder exists;

It is characterized in that it comprises the step of storing the MP3 files found in the subfolder in a list.

Here, in particular, after the step of storing the MP3 files found in the subfolder in the list, it is characterized in that the list is made by repeatedly searching and storing the MP3 files in the other subfolder.

According to the present invention, when selecting an MP3 file folder to be played, it is possible to play all the songs without searching additional files or folders by automatically searching the subfolders and automatically generating the MP3 file list.

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

1 is a flowchart illustrating a folder searching method for MP3 playback according to the present invention. As shown in the figure, first, a step of searching for an MP3 file in a root folder which is a top-level folder is performed (S101).

When the MP3 file is searched in the search step in the top root folder (S102), the searched MP3 file is stored in a list (S103). Here, the list is for storing and managing separately searched MP3 files.

Subsequently, after storing the searched MP3 file in a list (S103), it is determined whether a subfolder to be searched exists (S104). This is to search for the MP3 file in the subfolder of the root folder which is the top-level folder. First, it is determined whether a subfolder exists (S105).

Then, if a subfolder exists in the step S105 of determining whether the subfolder exists, a step of searching for an MP3 file in the subfolder is performed (S106).

Then, the step of storing the MP3 files found in the subfolder in the list is performed. Here, the MP3 files searched in the subfolder are stored together in the list in which the MP3 files searched in the top root folder are stored.

Subsequently, as with searching and storing the above subfolders, the MP3 files are searched for in the other subfolders repeatedly and stored in the list. Here, all MP3 files are stored in a list created by searching in a subfolder repeatedly.

Therefore, the user can list and store MP3 files in all folders with one folder selection, and can move within the created list without moving to another folder or requiring another search.

2 is a view for explaining an embodiment of a folder search method for MP3 playback according to the present invention. As shown in the figure, the upper root folder is composed of a plurality of subfolders, and the plurality of subfolders are configured in a root form in which other subfolders exist.

In the method for searching a folder configured as described above, a search is first started in a root folder to search for MP3 files in the root folder. As shown in FIG. 2, the MP3 file called Song 01 found in the root folder is stored in a list.

Next, subfolders of the root folder are sequentially searched. There are three subfolders of DIR1, DIR2, and DIR3 in the root folder of FIG. 2, and the MP3 files are searched in each folder in the order of these subfolders DIR1, DI12, and DIR3.

As shown in FIG. 2, there are no other subfolders in the DIR1 subfolder, and there are three MP3 files of the searched song 02, song 03, and song 04, and the searched MP3 files are stored in the list.

In addition, two other subfolders, DIR21 and DIR22, are searched for in the DIR2 subfolder of FIG. 2, and only another subfolder exists in the DIR subfolder and no MP3 file exists.

Subsequently, the MP3 files are searched again in the subdirectories DIR21 and DIR22. There is no other subfolder in the DIR21 subfolder of FIG. 2, and there are two MP3 files of Song 05 and Song 06, and the retrieved MP3 files are stored in the list.

The DIR22 folder is searched to find the MP3 file of the song 07 and stored in the list, and the existence of a subfolder of the DIR221 is also known, and the subfolder DIR221 is searched again.

Accordingly, no subfolder exists in DIR221 of FIG. 2, and one MP3 file of song 08 is searched for and stored in the list.

Then, it is searched if there is an MP3 file in the subfolder of DIR3.

As above, all folders are searched and the MP3 files found are listed and finished.

That is, the list of the finally created MP3 file is as follows. Song 01, Song 02, Song 03, Song 04, Song 05, Song 06, Song 07, and Song 08.

As mentioned above, once a list of MP3 files is organized, all MP3 files under the selected folder are all organized in the list, so there is no need to create a list again. Can be.

Therefore, in case of portable or car MP3 or CD player that plays MP3 files stored in CD, all the MP3 files in the CD are searched and played just by searching the CD root folder. Has the effect of moving.
