Method and system for managing cloud storage

1. A method for integrally managing at least one cloud storage by a cloud storage management system of a first electronic device, comprising:

configuring, as a main drive, a network drive for a first cloud storage of a first server on the first electronic device, the first cloud storage assigned to a user of the first electronic device;

linking a second cloud storage of a second server used by the user to the first electronic device through the network drive, the second cloud storage being linked to the first electronic device as a sub drive to the main drive;

linking a second electronic device used by the user as an external storage to the first electronic device through the network drive, the second electronic device being linked to the first electronic device as a sub drive to the main drive;

integrally managing the first cloud storage of the first server, the second cloud storage of the second server, and the second electronic device used by the user as the external storage on the first electronic device through the network drive;

providing a function of classifying duplicate pictures based on similarity of pictures stored in the first cloud storage of the first server, the second cloud storage of the second server, and the second electronic device used by the user as the external storage; and

providing a user interface for selectively deleting at least one of the classified duplicate pictures in response to a selection from the user on the user interface,

wherein the integrally managing comprises collecting metadata of a file stored in the second cloud storage through the network drive to provide a meta service for the second cloud storage.

2. The method of claim 1 , wherein the method further comprising: providing a file tree of the second cloud storage.

3. The method of claim 2 , the method further comprising:

providing an editing function of the file stored in the second cloud storage through the network drive.

4. The method of claim 1 , the method further comprising:

generating a service folder of the first cloud storage and a service folder of the second cloud storage in a root folder of a file system of the first electronic device for integrated management.

5. The method of claim 1 , wherein integrally managing the cloud storage comprises integrally managing the first cloud storage, the second cloud storage, and the second electronic device through the network drive.

6. The method of claim 5 , the method further comprising:

collecting meta data of a file stored in the second electronic device through the network drive; and

providing file tree access and edit function to the second electronic device.

7. The method of claim 1 , the method further comprising:

collecting files stored in the first cloud storage and the second cloud storage by file types through the network drive; and

providing a file list.

8. The method of claim 1 , wherein the classifying of duplicate pictures further comprises:

classifying the duplicate pictures through filtering based on tag or meta information of the pictures stored in the first cloud storage, the second cloud storage, and the second electronic device as the external storage.

9. A non-transitory computer-readable recording medium storing a set of instructions that, when executed by a processor, causes the processor to perform a method for integrally managing at least one cloud storage by a cloud storage management system of a first electronic device, wherein the method comprises:

configuring, as a main drive, a network drive for a first cloud storage of a first server on the first electronic device, the first cloud storage assigned to a user of the first electronic device;

linking a second cloud storage of a second server used by the user to the first electronic device through the network drive, the second cloud storage being linked to the first electronic device as a sub drive to the main drive;

linking a second electronic device used by the user as an external storage to the first electronic device through the network drive, the second electronic device being linked to the first electronic device as a sub drive to the main drive;

integrally managing the first cloud storage of the first server, the second cloud storage of the second server, and the second electronic device used by the user as the external storage on the first electronic device through the network drive;

providing a function of classifying duplicate pictures based on similarity of pictures stored in the first cloud storage, the second cloud storage, and the second electronic device used by the user as the external storage; and

providing a user interface for selectively deleting at least one of the classified duplicate pictures in response to a selection from the user on the user interface,

wherein the integrally managing comprises collecting metadata of a file stored in the second cloud storage through the network drive to provide a meta service for the second cloud storage.

10. A system for integrally managing at least one cloud storage implemented by a computer, the system comprising at least one processor implemented to execute computer-readable instructions, wherein the at least one processor comprises:

a drive configuring unit to configure, on a first electronic device, a network drive for a first cloud storage of a first server as a main drive, the first cloud storage assigned to a user of the first electronic device;

a storage linking unit configured to link, through the network drive, a second cloud storage of a second server used by the user and a second electronic device used by the user as an external storage to the first electronic device, the second cloud storage being linked to the first electronic device as a sub drive to the main drive, the second electronic device being linked to the first electronic device as a sub drive to the main drive; and

a meta service providing unit configured to:

integrally manage the first cloud storage, the second cloud storage, and the second electronic device used by the user as the external storage through the network drive;

provide a function classifying duplicate pictures based on similarity of pictures stored in the first cloud storage, the second cloud storage, and the second electronic device used by the user as the external storage; and

providing a user interface for selectively deleting at least one of the classified duplicate pictures in response to a selection from the user on the user interface,

wherein the integrally managing comprises collecting metadata of a file stored in the second cloud storage through the network drive to provide a meta service for the second cloud storage.

11. The system of claim 10 , wherein the meta service providing unit is configured to: provide file tree access and edit functions to the second cloud storage.

12. The system of claim 10 , wherein the meta service providing unit is configured to:

generate a service folder of the first cloud storage and a service folder of the second storage in a root folder of a file system of the first electronic device for integrated management.

13. The system of claim 10 , wherein the meta service providing unit is configured to:

collect meta data of a file stored in the second electronic device through the network drive; and

provide file tree access and edit functions to the second electronic device.

14. The system of claim 10 , wherein the meta service providing unit is configured to collect files stored in the first cloud storage, the second cloud storage, and the second electronic device used by the user as the external storage by file types through the network drive and provide a file list.

15. The system of claim 10 , wherein the meta service providing unit is configured to classify the duplicate pictures through filtering based on tag or meta information of the pictures stored in the first cloud storage, the second cloud storage, and the second electronic device used by the user as the external storage.
