A user, upon specifying a print control file as a file to be transmitted,
an image file to be printed listed in the control file is also specified
as a file to be transmitted, and the image file is listed into a
transmission control file. This enables the user to transmit the image
file without transmitting it separately. A file specifying apparatus
employs a memory storing the image file and image file information that
specifies the image file. The apparatus is used together with a
transmitter that transmits the image file to a destination device for
printing the image file. The apparatus includes a reading unit for
reading the image file information from the memory and a controller for
adding print control file information into the transmission control file.
The print control file information specifies the print control file
including the image file information read out.
