Dividing or splitting data (e.g., images) of a file may be performed by allowing a user to preview or otherwise view the intended division prior to the splitting of the images in the file into separate files. The division may be shown in a display by visually distinguishing between the designated groups. Visual distinctions may include color filtering, use of a division mark, use of grouping frames, labeling and the like and/or combinations thereof. By allowing a user to view the intended groupings, a user may further cancel designated groupings prior to splitting the images into the separate files.
