Information processing system and method of processing information

A method performed by an information processing system including an information processing apparatus and a plurality of terminal devices, the method comprising:

• storing, by a first memory unit of a first terminal device included in the plurality of terminal devices, information of the first user;
• acquiring, by a first acquisition unit of the first terminal device, a file name of one file included in at least one file stored in the information processing apparatus using the information of the first user stored by the storing by the first memory unit;
• receiving, by a first reception unit of the first terminal device, an instruction of sending the file name of one file acquired by the acquiring by the first acquisition unit;
• sending, by a first send unit of the first terminal device, when the instruction is received by the receiving by the first receiving unit, the message, which includes the information of the first user used to acquire one file in the first acquisition unit and access information for accessing one file and a destination of which is the second user, to another information processing apparatus connected to the first terminal device;
• receiving, by a receiving unit of a second terminal device included in the plurality of terminal devices, a message sent from the first terminal device from the another information processing apparatus based on information of the second user;
• receiving, by a second reception unit of the second terminal device, a selection of the message which includes the information of the first user and the access information among the message received by the receiving by the receiving unit;
• acquiring a second acquisition unit of the second terminal device, one file specified by the access information in the message using the information of the first user included in the message when the selection is received by the receiving by the second reception unit;
• storing, by a second memory unit of the information processing apparatus, the at least one file and the information of the user who can access each of the at least one file;
• determining, by a determination unit of the information processing apparatus, whether one file is sent to the second terminal device based on the information of the first user used to acquire one file by the second terminal device and information of the user who can access one file, the information of the user who can access one file being stored by storing by the second memory unit;
• and
• sending, by a second send unit of the information processing apparatus, one file to the second terminal device when the determining by the determination unit determines that one file is sent to the second terminal device.
