I just downloaded a 600MB game from KaZaa and it's a .BIN file. How do I open it to install the game???

A .cue file tells burning software how to burn the .bin file. So basically, just load up your burning software of choice, burn an image, and select the .cue file. It's just like burning an .iso ...

To open and view the contents of a MacBinary file, you must have a program that is capable of uncompressing the binary file type. You can use Stuffit Expander to open compressed files.
