I can envision a need to be able to rename files and images using a formula pulling data out of various fields in the record. For records that have more then one file or image in the fires and images field there could be a way to detect the original extension of the files so to adjust the file name based on the extension and when there are multiple files or images in one record there could be an prefix/postfix identifier such a (1), (2), (3) or (A), (B), (C). Having this ability would allow for exports of these files or images to have a filename that makes sense as per the data in the record.
