In an information-processing device, a controller operates according to setting information. The controller executes selective one of a swap mode and a copy mode. The swap mode is for moving the setting information from one device to another device. The copy mode is for copying the setting information from one device to one or more devices. While a removable medium is connected to the input-output interface: the controller performs; in a swap-mode case where the swap mode is executed, storing in the removable medium the setting information currently stored in the memory and overwriting the setting information in the memory to prescribed initial setting information; and in a copy-mode case where the copy mode is executed, storing in the removable medium the setting information currently stored in the memory while maintaining the current setting information in the memory.
