1. A multi-function image forming apparatus comprising: an operational display to provide a graphical user interface (GUI) including a profile selection GUI portion that provides, for user selection, plural registered document processing profiles corresponding to respective specific scan image targets, each registered document processing profile indicating a specific pre-configured division size corresponding to a maximum file size limitation permitted by a respective specific scan image target; a document scanner to scan a hardcopy document and generate one or more scan document images, and submit the scan document images for further processing according to a selected document processing profile corresponding to a specified scan image target; and a file conversion module embodied in a non-transitory storage medium and executable by a processor to process the scan document images according to the selected document processing profile, wherein the file conversion module processes the scan document images in accordance with the specific pre-configured division size indicated in the selected document processing profile amongst the plural registered document processing profiles, and based on the selected document processing profile, assembles the scan document images sequentially into divided image files each having a file size no greater than the specific pre-configured division size specified by the document processing profile corresponding to the specified scan image target, and sends, to the specified scan image target corresponding to the selected document processing profile, the multiple divided image files as a grouping of the divided image files associated with the hardcopy document and assembled based on the document processing profile corresponding to the specified scan image target to ensure that the divided image files comport with file size requirements of the specified scan image target.
