Conventionally, a user cannot give an instruction not to include predetermined information such as a date and time or a reception number in a file name of an image file. A method for controlling a document reading apparatus including a reading unit configured to read an image of a document to generate image data includes receiving an instruction not to set predetermined information as a file name of the image data generated by the reading unit, and, in a case where the instruction is received in the receiving, setting a file name not including the predetermined information.
