7. The method of claim 5, wherein content information and a time stamp that are recorded in the DB of the personal cloud device and lastly downloaded by the electronic device are determined to request updated content information from the personal cloud device.

8. The method of claim 5, further comprising:

if the second content is completely downloaded, transmitting a download result to the personal cloud device,

wherein the personal cloud device updates content information and a time stamp lastly updated by the electronic device based on the download result.

9. The method of claim 1, further comprising:

if the first content stored in the first folder is revised to generate a third content, determining an upload condition of the electronic device; and

if the upload condition satisfies a set condition, transmitting the third content to the personal cloud device,

wherein the personal cloud device stores the first and second contents together.

10. The method of claim 5, further comprising:

if a fourth content generated by revising the second content exists in the DB of the personal cloud device, downloading the fourth content from the personal cloud device; and

storing the downloaded fourth content and the second content together in the second folder.

11. The method of claim 5, wherein, if an external device is connected to the personal cloud device through a wire, and content stored in the external device is uploaded into the personal cloud device, the personal cloud device updates the DB of the personal cloud device, and the electronic device downloads the content stored in the external device from the personal cloud device.

12. The method of claim 5, wherein, if an external device is connected to the personal cloud device through a wire, and a new sixth content is overwritten on a fifth content stored in the personal cloud device through the external device, the personal cloud device stores the sixth content and a time stamp when the sixth content is overwritten, in the DB, and the electronic device determines the time stamp to download the sixth content in order to store the sixth content and the fifth content together.

13. An electronic device comprising:

a communicator configured to communicate with a personal cloud device configured to share contents with another device;

a storage unit configured to store the contents; and

a controller configured to control the communicator to determine an upload condition of the electronic device if a new first content is added to a set first folder of the storage unit, and to transmit the first content to the personal cloud device if the upload condition satisfies a set condition.

14. The electronic device of claim 13, wherein the upload condition comprises at least one of a status of a network connected between the electronic device and the personal cloud and battery information of the electronic device.

15. The electronic device of claim 14, wherein, if the electronic device and the personal cloud device are connected to each other through a set network interface, and a residual amount of a battery of the electronic device is higher than or equal to a set value, the controller controls the communicator to transmit the first content to the personal cloud device.
