Seeing What a .bin file is

[checkmate]

Second and probably nearer to what you want to know is use
winiso.

I would do a copy and paste of the original bin to another folder,
rename the bin file

eg c:\?????.bin to c:\?????.iso


right click and then open the file and all the contents will be revealed from within the winiso program.

The copy and paste is so you can leave the original bin file unchanged.
