An image processing apparatus recognizes a character string included in image data generated by a reading unit, displays the recognized character string, receives a selection, performed by a user, of the displayed character string. The image processing apparatus thereafter determines, as a storage destination for the image data, a folder named with the character string that is based on the received selection and thereby stores the image data in the determined storage destination. Additionally, the image processing apparatus, in response to a reading instruction being issued once, reads images of a plurality of documents to generate image data, receives a plurality of times selection, performed by the user, of the displayed character string, and determines, as storage destinations, a plurality of folders named with the respective character strings that are based on the selection received a plurality of times.
