I use ImgBurn to backup all my software media (CDs and DVDs). I haven't put my finger on why it acts this way yet, but sometimes when I choose to create an image file it defaults to a BIN file and other times an ISO. I can change it of course, but I always want ISO files, never BIN files. I wondered why it changes back and forth (something with the original disc structure maybe?) and if I could force it to always use ISO files and never BIN files? Thanks in advance!
