Abstract

In response to a requirement of transferring a file from a personal computer PC to a projector 10 that is output by dragging and dropping a corresponding file icon onto a projector icon, a CPU 50 requires setting of a password. The CPU 50 maps the preset password to a file and transfers the file with the password to an external storage device of the projector 10. The projector 10 requires input of a password, which is expected to be assigned to the file, and allows reproduction of the file when the input password is coincident with the preset password.

Claims

1. A method of storing data to be displayed with a projector via a computer, said method comprising the steps of:

specifying data to be displayed;

determining whether or not a requirement of storing the specified data into a storage device is output;

when it is determined that the storing requirement is output, requiring setting of a password;

mapping the preset password to the specified data; and

transferring the data with the password to said storage device, wherein it is determined that the requirement of storing the specified data into said storage device is output, when an icon representing the specified data is dragged and dropped onto an icon representing said storage device on a display screen of said computer.
