Referring to FIG. 2, a file storage apparatus 100 according to an embodiment of the present invention may include a first storage unit 110 and a second storage unit 120.

The first storage unit 110 may store at least one file. The first storage unit 110 may have a directory structure as shown in FIG. The first storage unit 110 may store a local file in a subdirectory of the root directory. Also, the first storage unit 110 may not store any local file.

The first storage unit 110 may store information about files stored in the respective cloud storage units 300 in a subdirectory of the root directory. Referring to FIG. 3, the first storage unit 110 may include a directory corresponding to each of the cloud storages 300.

3, the first storage unit 110 is a subdirectory of a "cloud" directory that is a subdirectory of a root directory, and includes a "CSP1" directory corresponding to the first cloud storage 310, CSP2 "directory corresponding to the second cloud storage 300, and a" CSP3 "directory corresponding to the third cloud storage 300. [

Information about the files stored in each cloud storage 300 may be stored in the corresponding directory. For example, information about files stored in the first cloud storage 310 may be stored in the "CSP1" directory.

For example, a dummy file having a file name corresponding to the file name of each file stored in the first cloud storage 310 may be stored in the "CSP1" directory. The size of the dummy file may be zero. The dummy file may contain metadata.

The metadata may include information about the corresponding file. The metadata may include, for example, information about the kind of the corresponding file, the creation time, the modification time, or the access time. If the corresponding file is a music file, the metadata may include information on the artist name, the album name, the track number, the name of the song, the reproduction time, the bit rate, the codec information, or the genre. Depending on the type of the corresponding file, various pieces of information can be included in the meta data.

The second storage unit 120 may store at least one file. The second storage unit 120 may have a directory structure as shown in FIG. The second storage unit 120 may store a result of classifying the files stored in the first storage unit 110 according to at least one criterion in a subdirectory of the root directory.

For example, the second storage unit 120 may store a result of sorting at least one or more files stored in the first storage unit 110 according to file types. 3, the second storage unit 120 may include an "images" directory or a "videos" directory as subdirectories of a "contents-centric" directory which is a subdirectory of the root directory.

If any one of the files stored in the first storage unit 110 is a picture file, the link file indicating the file can be stored in the "images" directory of the second storage unit 120. [ Also, if any one of the files stored in the first storage unit 110 is a video file, the link file indicating the file can be stored in the "videos" directory of the second storage unit 120. [

Also, the second storage unit 120 may store the result of classifying at least one or more files stored in the first storage unit 110 using metadata included in the file. 3, the second storage unit 120 may include a "pop" directory or a "ballad" directory as a subdirectory of the "metadata-centric &

When the genre of the music file is "pop" as a result of referring to the metadata of one of the music files stored in the first storage unit 110, the link file indicating the music file is stored in the second storage unit 120, Quot; pop "directory of < / RTI > When the genre of the music file is "ballad " as a result of referring to the metadata of any one of the music files stored in the first storage unit 110, the link file indicating the file is stored in the second storage unit 120 Quot; ballad "directory of < / RTI >

In other words, the plurality of link files stored in the second storage unit 120 may point to the same dummy file.

In addition, any one of the files stored in the cloud storage 300, the dummy file corresponding to the file and stored in the first storage unit 110, or the link file indicating the dummy file and stored in the second storage unit 120 may be deleted , The file, the dummy file, and the link file may all be deleted in order to maintain the integrity.

4 is a flowchart illustrating a process of performing a file management method according to an embodiment of the present invention. Referring to FIG. 4, a file management method according to an embodiment of the present invention includes a step (S100) of receiving information about a file stored in the cloud storage 300 from each of at least one cloud storage 300 .

The information on the file may include, for example, a file name of the file, a file type, a file creation time, a modification time of the file, or an access time of the file. If the file is a music file, the information on the file may include information on the artist name, album name, track number, song name, play time, bit rate, codec information, or genre. Also, depending on the type of the file, various information may be included in the information on the file.

Next, a dummy file corresponding to the received file may be generated using the information about the received file, and the dummy file may be stored (S110). The dummy file may have a file name corresponding to the file name of the file stored in the cloud storage 300. The size of the dummy file may be zero. In addition, the dummy file may include metadata. The metadata may include at least a part of information on the received file.

Each dummy file can be stored in a file system having a directory structure. Each dummy file may be stored in the first storage unit 110 having a directory structure. For example, each dummy file may be stored in a directory of the first storage unit 110 corresponding to the cloud storage 300 in which the file corresponding to the dummy file is stored.

Next, a result of sorting the dummy file according to at least one criterion using information on the received file may be performed (S120). For example, the result of classifying each generated dummy file according to the type of the file may be stored in the second storage unit 120. The result of classifying each generated dummy file based on at least a part of the meta data included in the dummy file may be stored in the second storage unit 120. [

Specifically, in step S120 of storing a result of sorting the dummy file, a link file indicating the dummy file may be generated first. Next, each link file can be stored in the second storage unit 120 having a directory structure. For example, each link file may be stored in a directory corresponding to the metadata of the dummy file among the directories of the second storage unit 120 generated according to the criteria.
