.cue and .bin files

I just found out what these file types were. I thought I could use Stuffit Expander to open a .bin file thinking it was a MacBinary file type. I was so frustrated I nearly deleted the files when I found a post that said that they were PC files that could be burned (in conjunction) using Toast Platinum. I opened the files using Toast 6 and they burned like a dream. My next problem was that the files were for the PC and not Mac versions... duh.
