Abstract: A method and a system for integrally managing at least one cloud storage in a system for managing cloud storage implemented by a computer may include: configuring a network drive for a first cloud storage on a first server related to the system for managing cloud storage which is assigned to a user of a first electronic device; linking a second cloud storage on a second server used by the user; and integrally managing the first cloud storage and the second cloud storage through the network drive.

Abstract: A method for sharing file of a first electronic device used by a user using a share message implemented by a computer may include: uploading a file to be shared with a second electronic device used by the user to a server according to the share message transmitted through a chat session set between an account of the user of the first electronic device and the server providing a cloud service; storing the share message including a link of a storage location of the server for the file uploaded to the server as an instance message of a private chat room corresponding to the chat session; and displaying the share message stored as the instance message through the private chat room on a screen of the first electronic device, wherein the second electronic device may be configured to access the private chat room with the account of the user.

Abstract: A method of connecting a digital device to a remote personal computer (PC) includes: requesting an access to the remote PC in response to executing a remote PC service through a user interface for changing a setting of the digital device; setting a network connection for providing the remote PC service in response to identifying request information associated with the request from the remote PC; encoding, by the remote PC, screen information displayed on the remote PC as a moving picture; receiving, by the digital device, the encoded moving picture from the remote PC; and decoding, by the digital device the encoded moving picture and playing the screen information of the remote PC on a display of the digital device.

Abstract: A mobile cloud system includes a plurality of mobile terminals having at least one functional module and a communicator; a cloud server to receive the information acquired from the at least one functional modules, the cloud server including a read-only file system to provide services applied to all of the plurality of connected mobile terminals, a read/write file system to provide independent services applies to each of the plurality of connected mobile terminals, and a controller to control operations of the both file systems; and a wireless communication network to provide a network between the plurality of mobile terminals and the cloud server.
