An image file editing apparatus avoids duplicated display of image files when image files are being displayed from multiple recording medium that are removably insertable into the apparatus. A medium drive device writes and reads files stored in the removable recording medium. A list display device obtains or creates identification information of the image file in the recording medium and displays the image file in a list using identification information. A file selection device selects an image file displayed in the list corresponding to an external operation. An editing device executes an editing operation to one or a plurality of selected image files. The image file editing apparatus can also include a medium collating device that searches for identification information from a currently-installed recording medium, and that determines whether the recording medium has already been displayed in the list. The list display device displays the image files in a newly-installed recording medium in the list, when the list display device has determined by a collation result of the medium collating device that the recording medium is a newly-installed recording medium.
