A network system includes a print server to which a printer is connected, a file server, and one or more client terminals, wherein the print server, the file server, and the one or more client terminals are connected together on a network. The client terminal includes a printer driver that controls the printer, a first setting file in which setting information of the printer driver arranged in a first folder, in which the printer driver is arranged, is stored, and a second setting file in which the setting information arranged in a second folder other than the first folder is stored. When the setting information is newly created or changed, a third file in which the setting information is written is arranged in the file server. In addition, address information of the third file that is arranged in the file server is stored in a memory area of the print server.
