BIN - Binary Disc Image is a format you can use to save data from a DVD or even a CD. This type of format can also be noticed by any device just as a disc itself. It is also similar to .ISO and only saved with other similar files that bring out the contents of the disc. You can always open up a BIN file if it will not open using other disk tools. You can easily change the extension from .bin to .iso. When you save this type of binary disc file, usually people save them with a .CUE file. It will give you information on the ordering of data.
