receiving a request for executing a process corresponding to one or more files or folders in the list of information;

executing a process corresponding to the request for executing a process received based on the second authentication information when the one or more files or folders are to be managed by the other information processing device,

wherein the client device includes a second memory that stores second program, and a second processor;

wherein the second processor executes the second program so as to perform a method including the steps of;

sending a request for receiving a list of files to the information processing device;

displaying the list of the files or folders on a display of the client device based on the list of files that is send from the information processing device in response to the request for receiving the list of the files,

receiving an operation of the one or more files or folders in the list of the files or folders, and

sending the request for executing a process corresponding to the received operation.

2. The system according to claim 1, wherein the first processor receives the file or folder that is managed by the other information processing device accessible based on the second authentication information, and updates the file or folder that is managed by the other information processing device accessible based on the second authentication information, said second authentication information being associated with the each user when stored in the first memory.

3. The system according to claim 1, wherein the second processor distinguishes the file or folder that is managed by the information processing device accessible based on the first authentication information from the file or folder that is managed by the information processing device accessible based on the second authentication information when displayed on the display of the client device.

4. The system according to claim 1, wherein the second processor sends a search request to the information processing device along with a search condition, and wherein the second processor displays the list of the file or folder on the display of the client device based on information of the one or more files or folders that is sent from the information processing device in response to the search request, and

wherein the first processor, based on the search condition sent from the client device, searches one or more files or folders based on information of the file or folder that is managed by the information processing device that is accessible based on the first authentication information and information of the file or folder that is managed by the other information processing device that is accessible based on the second authentication information, and sends the client device the file or folder that is searched.

5. The system according to claim 1, wherein the second processor receives an instruction for uploading a file corresponding to the one or more folders among the list of the file or folder on the display of the client device, and sends the request for executing a process of downloading of the file corresponding to the one or more folders in response to the instruction, and

wherein the first processor uploads the file to a folder that is managed by the other information processing device based on the second authentication information when the one or more folders are to be managed by the other information processing device.

6. The system according to claim 1, wherein the second processor receives an instruction for downloading the one or more files among the list of the file or folder on the display of the client device, and sends the information processing device a request for executing a process of downloading of the one or more files in response to the instruction, and

wherein the first processor acquires a file to be managed by the other information processing device based on the second authentication information when the one or more files are to be managed by the other information processing device, and sends the acquired file to the client device.

7. The system according to claim 1, wherein the search condition includes search refinement and search order based on types of attribute information of index information of the one or more files or folders.

8. An information processing device, comprising:

a first memory that stores a first program, and
